Opis:
PIV technology was used to investigate the influence of the particles’ relevant parameters on the instantaneous movement characteristics in the sandblast cylinder under the circumstance of different particle sizes, different section heights and different stacking conditions. As the diameter increased, particles had a greater velocity and energy when approaching the wall, which would cause a serious abrasion. The influence of test selection factors on the particles’ radial velocity of particles was greater than that on axial velocity. The radial velocity and axial velocity on the surface of the cylindrical section were all reduced to a lower level when the particles approach the tank wall. When r > 0.3 R, the particle velocity maintained at a higher level, but then decreased slowly when r > 0.7 R. Therefore, the abrasion of the conical section of the sandblast cylinder when r > 0.3 R should be paid more attention to.

In the domain of the equipment and apparatus construction, a permanent preoccupation worldwide is ensuring technical performances and high fiability in exploitation. The users’ requirement growth in this field led to producing materials with high characteristics such as iron-nickel alloys having a high nickel content with special magnetic, thermal, or elastic properties. The theoretical and experimental researches had the aim of obtaining cold rolled strip, thin (2.6 mm) and narrow (86 mm) from iron-nickel alloys with 41% Ni (low content of C: 0.02-0.04%; Fe: 58%; other elements: Mn, Si, Cu, Cr, Al: under 1%). Our own experiments aimed to establish an optimal cold rolling technology of hot rolled strips of iron-nickel alloys, in order to obtain cold rolled strips with superior mechanical and technological characteristics, strip profile according to current standards, including a finished product characterization.

Opis:
General lighting is the most common way of illuminating interiors and the source of electricity consumption in buildings. This fact forces the search for lighting solutions effective both for people and the environment. In this study the impact of room and luminaire characteristics on general lighting conditions and energy efficiency in interiors is considered. In rooms of different sizes and reflectances, seventeen luminaire types with various light distributions were arranged in uniform layouts. The levels of average illuminance, uniformity and normalised power density related to two horizontal working planes were calculated. The impact of working plane reduction, room index and reflectances, lighting class and luminous intensity distribution of luminaire on the considered parameters was investigated. The use of the reduced working plane resulted in the increase in the average illuminance (7.7% on average), uniformity (33% on average) and normalised power density (23% on average). The impact of the room index and lighting class on the average illuminance and normalised power density was significant while the impact of the luminaire luminous intensity distribution and room reflectances was low. The normalised power density levels of the general electric lighting in interiors, with luminaire luminous efficacy of 100 lm/W, are in the following range: 1.08‒3.42 W/m2 per 100 lx. Based on these results a normalised power density level of 2 W/m2 per 100 lx is recommended for designing and assessing the new general electric lighting systems in buildings.

Opis:
The history of hybrid vehicles has started between the 19th and the 20th century because then the first project of a hybrid vehicle was constructed. The first man who manufactured a front hub mounted electric propulsion connected with a generator powered by a spark ignition engine was Ferdinand Porsche. This vehicle was called the Lohner- -Porsche Electromobile. The first mass-produced hybrid vehicle was the first generation Toyota Prius. The model premiere was in 1996 and the production started one year later. The vehicle was equipped with a 1.5 dcm 58 hp spark ignition engine and with the added electric propulsion. It generated 40 mechanical hp. Since 2000, a 72 hp spark ignition engine and a 44 hp electric generator were mounted. Fuel consumption of this model was 5 litres per 100 km. In the early 2000s, 95% hybrid vehicles were the Toyota Prius. The biggest competitor to the Toyota Prius was the Honda Insight. Lexus and Mercedes started manufacturing hybrid vehicles few years later. The most popular car brands that sell hybrid vehicles are Toyota and Lexus from Toyota Motor Corporation. This article describes an example of diagnostic possibilities for the hybrid vehicle system. The construction of vehicle models that use two propulsion systems (spark ignition engine and electric generator) results in the development and increase in control system devices. The measurements were made using various diagnostic devices, e.g. a diagnostic scanner, mustimeter, megohm-meter and oscilloscope. The reading of fault codes is not enough so it is necessary to use a mustimeter or a megohm-meter to examine the signal characteristics, which is presented in this article.

Opis:
The paper describes a combined cycle power plant with carbon capture installation in a post-combustion technology. Carbon dioxide is separated from flue gas by using a chemical absorption method with monoethanolamine (MEA) as a sorbent. Separated carbon dioxide is compressed in order to prepare for transportation to the storage place. This paper identifies the electric efficiencies and other characteristic parameters of power plants before and after implementation of CO2 capture installation, as well as the power plant efficiency drop, and the improvement of ecological characteristics related to the implementation of this installation. The implementation of the installation described herein is associated with the efficiency loss caused by the auxiliary power for additional installations. The CO2 separation installation is powered by heat energy required for reclaiming the sorbent. This energy is taken in the form of steam extracted from the steam cycle, thus reducing the steam turbine power output, while the CO2 compression installation is powered by electric energy.

The properties of barium titanate (BaTiO3, BT), such as high dielectric constant and resistivity, allow it to find numerous applications in the field of microelectronics. In this work silicon metal-insulator-semiconductor field effect transistor (MISFET) structures with BaTiO3 thin films (containing La2O3 admixture) acting as gate insulator were investigated. The films were produced by means of radio frequency plasma sputtering (RF PS) of sintered BaTiO3 + La2O3 (2% wt.) target. In the paper transfer and output I-V, transconductance and output conductance characteristics of the obtained transistors are presented and discussed. Basic parameters of these devices, such as threshold voltage (VTH) are determined and discussed.

The engine output characteristic offers very important information during the real application of the HCCI technology. This kind of combustion process significantly influences the wearing degree of the main engine components or even the engine damage. The principle of the HCCI combustion is basically beneficial, however, it can also be destructive. Described in this article are measurements of the engine output characteristics in the case of an experimental piston combustion engine. These measurements were performed by means of a data recording system, whereby the detonation combustion was evaluated using a quantitative method. The real values of atmospheric conditions and fuel mixture composition were added to the measured values. The resulting values were visually compared with a degree of the engine piston damage caused by the detonations. The final result is a limit value, which represents a maximal number of the detonation units that are permissible in order to ensure reliable operation of the HCCI engine.

Opis:
It should be noted that there is currently a problem with wood resources in the woodworking industry. A potential, unused wood reserve is post-consumer wood (PCW). The problem with the quality of this wood resource has not been fully resolved since there is no regulatory database. In fact, there is a lack of appropriate regulatory documents, which makes it impossible to describe to a full extent the physical and mechanical properties of PCW of common wood species of different ages as a source of additional raw materials for various woodworking technologies. Proceeding from the goal, the task of the study is to describe the physical and mechanical properties of postconsumer wood using the example of fir wood, which for a long period of time has been used to create furniture and joinery products. The task is also to identify patterns of change in the indicators of this resource with age – an expired service life or suitability. In order to use PCW in woodworking and to fill the scientific base with physical and mechanical indicators of fir wood of different ages with an expired product service life, the following characteristics were investigated: static hardness, swelling, coefficients of swelling, the value of transverse anisotropy, density, static bending strength, splitting strength along the fibers, modulus of elasticity in compression, and the modulus of elasticity in static bending. The characteristics of PCW of the widespread fir species in the range of use from 0 to 20 years were explored, with intermediate control over the properties every 5 years. The dynamics of the physical and mechanical indicators of fir PCW were revealed and it was found that in the course of operation time in various conditions they change, mainly decreasingly: static hardness by 9.2-9.6%; the value of transverse anisotropy by 30-32%; strength: static bending strength by 3.4-7.95%, splitting strength by 4.49-8.67%; modulus of elasticity: in compression by 3.89-4.08%, in bending by 2.75-6.64%. The main causes of changes in the properties of PCW with age: natural: weathering, partial internal rot, insect damage, other biological effects; mechanical: splitting, scratches, small holes from means of fastening and other defects due to use; operational: the influence of power and dynamic loads, the influence of surface finishing agents and other factors on the structural elements of wood products. A summary table was compiled for the selection of indicators of the physical and mechanical properties of fir PCW of different ages. When knowing the indicators and dynamics of the physical and mechanical properties of PCW with age, it can be recommended for manufacturing structural materials – blockboards and furniture panels.

Opis:
Today in woodworking, there are problems with the use of wood waste and the accumulation of involved wood as an additional and not fully used resource. The problem has not been completely solved, as there is no scientific basis and practical recommendations for efficient production processes with predicting the properties of products made from Post-Consumer Wood (PCW), in particular in the production of blockboards (BB). The objective of the studies is to substantiate and develop a scientific and technical basis for resource-saving and environmentally friendly technologies, to establish the influence patterns of PCW properties on the mechanical characteristics of the products obtained, to develop operating parameters and to formulate practical recommendations, confirmed by the results of experimental studies. The studies have proved the expediency of using PCW in technological processes of woodworking, in particular in the production of construction materials - blockboards with predicted characteristics. In order to rationally use raw materials for the manufacture of conventional blockboards made from Post-Consumer Wood (PCW-BB), new designs of a conventional PCW blockboard with a thickness of 22 mm and with a unified strip width of 16, 32, 48, and 64 mm, the strips are glued ones, 3 mm thick, and faced with plywood on both sides. The authors of the article found that in order to ensure improved operating characteristics of the blockboards, it is important to lay radial, semi-radial and tangential strips in structures with the ratio of width to thickness of the cross-sections of the strips - rationally and efficiently - 1:1, 2:1, 3:1. Substantiation on this basis of new designs of PCW blockboards makes it possible to reveal shortcomings of these products at the conceptual stage of the project and correct them before manufacturing taking into account the specified technical conditions and reducing costs at the development stage. Mathematical models for predicting the main characteristics of conventional PCW blockboards (PCW-BB) have been constructed, which made it possible to determine the indexes of the bending strength of the BB across the strips, σBB, and the shear strength of the BB along the glue line, τВВ. The coefficients of approximation of mathematical dependencies for predicting the strength of PCW-BBs, the strips of which were made of fir wood, were calculated, which would allow for the selection of rational designs of blockboards with appropriate characteristics. It has been established that the developed mathematical models make it possible to predict the characteristics of the PCW-BB depending on the cross-sectional dimensions of the strips, the angle of the annual rings slope to the blockboard face and the age of the PCW, and, on this basis, to propose improved designs of these blockboards for the technological processes of woodworking. The influence patterns of the properties of structural elements on the indicators of conventional PCW-BB (500 × 500 × 22 mm) were experimentally established. It was found that an increase in the width of the strips leads to a decrease in the strength indexes (by 29-37%); an increase in the angle of the annual rings slope to the BB face leads to an increase in static bending strength (by 31-33%) but to a decrease in shear strength (by 4-7%); an increase in the age of the PCW leads to a decrease in strength indexes (by 3-8%). It was found that the physical and mechanical parameters of the experimental PCW-BBs with a strip cross-sections of 1:1, 2:1, 3:1 meet the requirements of the standard (larger values: for static bending of a rate of 15 MPa and for shearing at a rate of 1 MPa), and for the 4:1 cross- -section, they partially had lower indexes by 2-3%. To ensure the strength of the developed structures of the PCW-BBs, it is recommended to use the 3:1 ratio of the sides in the cross-section of the strips, and the slope of the annual rings to the blockboard face must be at least 45o. It was found that the deviation of the values obtained by mathematical models in determining the strength in static bending and shearing in comparison with the experimental ones did not exceed 8% and 10%, respectively.

Opis:
Among the technologies which allow to reduce greenhouse gas emission, mainly carbon dioxide, special attention deserves the idea of 'zero-emission' technology based on boilers working in oxy-combustion technology. In the paper the results of analyses of the influence of changing two quantities, namely oxygen share in oxidant produced in the air separation unit, and oxygen share in oxidant supplied to the furnace chamber on the selected characteristics of a steam boiler including the degree of exhaust gas recirculation, boiler efficiency and adiabatic flame temperature, was examined. Due to the possibility of the integration of boiler model with carbon dioxide capture, separation and storage installation, the subject of the analysis was also to determine composition of the flue gas at the outlet of a moisture condensation installation. Required calculations were made using a model of a supercritical circulating fluidized bed boiler working in oxy-combustion technology, which was built in a commercial software and in-house codes.

The aim of this paper is to present the requirements for the passive standard based on the example of the RES TTC building. The requirements were divided into main energy demand and detailed recommendations for each indicator. The calculations and analyses have shown that to achieve the required energy demand, better solutions than the recommended ones need to be applied, such as air handling units with better heat recovery efficiency. The same applies to the U heat penetration coefficient of heat for the outer partitions. The use of ventilation units with a recommended efficiency of 75% does not guarantee achieving a passive standard.

Opis:
The ceramic tile manufacturing process uses a lot of energy, mainly thermal energy, and to a lesser extent electric energy. Total energy costs account for between 50% and 55% of average direct manufacturing costs. Fossil fuel combustion, such as natural gas combustion, produces carbon dioxide emissions. Therefore, energy consumption and emissions issues are vitally important for both environmental effects and process costs in ceramic tile manufacturing. The wet process of granule production systems including wet grinding and spray drying is widely used for the production of granules. Although there is high energy consumption for the water evaporation in the spray dryer, it ensures to produce high quality tile for many years. In this study, important granule properties were introduced for a novel dry granule production system. In the successful application of a dry granulation system, the conformity of produced granules is vitally important such as particle size distribution, bulk density, flow properties, and moisture of granules and conformity for the pressing process. This paper includes the comparative studies for properties of granules produced in spray dryer and new dry granule preparation systems and the full results of the industrial trials with these granules. The cost comparison of both granule production systems was also made for the same raw material usage. The natural gas consumption and water consumption were reduced respectively from 46 to 15 m3/ton and from 540 to 95 liters/ton in the new dry granulation system while electricity consumption and maintenance costs remain almost the same in both systems.
