Opis:
Endogenous fires are currently one of the most common threats in hard coal mines. They are very dangerous for the staff and can cause very large economical loses. Therefore, the scope of activities aimed at limiting the possibility of these fires and reduction of their consequences constantly broadens. The paper presents the results of research aimed at determining the efficiency of the ventilation system applied to reduce the risk of endogenous fires in the areas where inert gases are used. The calculations included carbon dioxide and nitrogen. Inertisation is one of the ways of combating endogenous fires. This method is included in the developed comprehensive method to reduce the possibility of these fires. The results obtained and the method developed and later applied, should have a significant impact on improving the safety of operations in the scope of occurrence and consequences of endogenous fires.

Opis:
In this research work the influence of an inert catalyst on toxic emission from a self-ignition engine has been investigated. In particular polycyclic aromatic hydrocarbons (pahs) emissions, which are known to have mutagenic and carcinogenic properties, have been studied. The experimental results show that implementation of catalytic coating on chosen elements of diesel engine causes decrease in pahs concentration, what is connected with toxicity decrease in exhaust gases. The inert catalyst application (active coating on research engine glow plugs) is very advantageous for decrease of total polycyclic aromatic hydrocarbons (pahs) concentration in engine exhaust gases, especially on idle running. The applied modification of engine combustion space causes significant decrease of exhaust toxicity. Because of high effectiveness in pahs concentration and toxicity decrease it is recommended to continue the researches and extend them by various physical-chemical modifications of catalytic layers. The paper research work stand containing engine test house, engine with a break, fuel reservoir, NO, CO and smoke level analyzers, filter, tube with active coal, exhaust gases uptake system and engine control system. The pahs concentration marked in idle running diesel engine in two states of engine work, pahs concentration marked in diesel engine and the total pahs concentration in engine exhaust gases and pahs toxicity in engine exhaust gases for two engine loads are presented in the paper.

Opis:
This study considers solid planets at about 300 K and an inert atmosphere having no interaction with associated radiation. Processes considered include transfer of energy from the surface skin to underlying layers depending on thermal properties. Temperatures of the surface depend on the rates of transfer of energy between soil layers. The atmosphere is warmed at base by contact with the surface, convection and turbulence distributing higher temperatures through the air. Comparisons between theoretical and measured temperatures show a close similarity. Mean planetary temperatures are calculated, depending on thermal parameters and the intensity of light/radiation from the particular solar system.

Opis:
The volatile organic compounds (VOC's) are significant group o air pollution emitted during fuel combustion in diesel engines. This research work is continuation of research where the influence of an inert catalyst on toxic emission from a self-ignition engine has been investigated. In particular volatile organic compounds VOC's emissions which are known to have mutagenic and carcinogenic properties, have been studied. The experimental results show that implementation of catalytic coating on chosen elements of diesel engine causes change of percentage participation of particular compounds in their sum and decrease of their concentration. The analysis of chosen compounds (benzene and formaldehyde) shows that the modification which was proposed causes increase of concentration of those substances when engine works in specific conditions, what is connected with change of engine exhaust toxicity and decrease in PAHs concentration, what is connected with toxicity decrease in exhaust gases. In particularly research work stand, the comparison of total VOC's concentration with and without catalytic coating, the comparison of benzene concentration, the comparison of formaldehyde concentration, the comparison of toxicity level with and without catalytic coating are presented in the paper.

Opis:
This paper deals with the possibilities of using physical modelling to study the degassing of metal melt during its treatment in the refining ladle. The method of inert gas blowing, so-called refining gas, presents the most common operational technology for the elimination of impurities from molten metal, e.g. for decreasing or removing the hydrogen content from liquid aluminium. This refining process presents the system of gas-liquid and its efficiency depends on the creation of fine bubbles with a high interphase surface, uniform distribution, long period of its effect in the melt, and mostly on the uniform arrangement of bubbles into the whole volume of the refining ladle. Physical modelling represents the basic method of modelling and it makes it possible to obtain information about the course of refining processes. On the basis of obtained results, it is possible to predict the behaviour of the real system during different changes in the process. The experimental part focuses on the evaluation of methodical laboratory experiments aimed at the proposal and testing of the developed methods of degassing during physical modelling. The results obtained on the basis of laboratory experiments realized on the specific physical model were discussed.

This paper presents studies carried out in a pilot-scale plant for recovery of waste heat from a flue gas which has been built in a lignite-fired power plant. The purpose of the studies was to check the operation of the heat recovery system in a pilot scale, while the purpose of the plant was recovery of waste heat from the flue gas in the form of hot water with a temperature of approx. 90 °C. The main part of the test rig was a condensing heat exchanger designed and built on the basis of laboratory tests conducted by the authors of this paper. Tests conducted on the pilot-scale plant concerned the thermal and flow parameters of the condensing heat exchanger as well as the impact of the volumetric flow rate of the flue gas and the cooling water on the heat flux recovered. Results show that the system with a condensing heat exchanger for recovery of low-temperature waste heat from the flue gas enables the recovery of much higher heat flux as compared with conventional systems without a condensing heat exchanger.

Opis:
The oil industry is characterized by an intense impact on the environment, which inevitably causes its change. In the production process, the existing state of the environment in the territories of industrial facilities is completely or partially disturbed. Today, the result of the negative environmental impact of the fuel and energy industry on the nature of the regions of northern Russia has resulted in millions of tons of drilling and oil production waste stored in sludge pits and causing colossal damage to the atmosphere, hydro- and lithosphere of the country’s oil-producing territories. The aim of this work is to improve the technological process of utilization of drilling waste in the fields with the receipt of an inert building material that does not have a negative impact on the components of the natural environment. In the course of work, based on the analysis of the proposed disposal methods, the most optimal option was selected and a technology for disposal of drilling waste at an oil field was developed, a situational map of the object was presented, and an estimate of the cost of the proposed disposal technology was carried out. Based on the results of the work carried out, a conclusion was made about the effectiveness of the utilization technology under consideration, since it was revealed a decrease in the amount of generated and accumulated waste, a decrease in the costs of maintaining and reclamation of waste accumulation / disposal facilities.

The effect of inert media and fertilization levels on nutrition status of green house tomato cv. ‘Maeva F₁’ was investigated. Mean microelement content was: 118.5 mg Fe, 51.7 mg Zn, 269.0 mg Mn and 11.43 mg Cu kg⁻¹ of dry mass of the index parts of the tomato (9–10 leaf form the top). No significant effect of rockwool, expanded clay and polyurethane foam on microelement contents was found in the index parts of the greenhouse tomato, except for zinc whose content was significantly higher in the leaves of the plants grown in rockwool and polyurethane foam than in expanded clay. Fertilization levels did not affect significantly the content of iron, manganese and copper in the index parts, except for zinc whose content lowered at higher fertilization level. High tolerance of the tomato plants to zinc and manganese content in feeding solutions was indicated. No phytotoxicity of zinc nor manganese was found at the content of 2.01 mg Zn and 1.78 mg Mn dm⁻³ of water or feeding solution.

Opis:
This work introduces dynamic mechanical thermal analysis (DMTA) as an efficient method for the assessment of the shelf life of solid composite solid propellants in air and nitrogen atmospheres. The samples were aged at three temperatures 323.15, 333.15, and 343.15 K for 60, 120, and 180 days. The two different methods of Arrhenius and Berthelot were used to compare the effects of air and nitrogen atmospheres on the ageing of composite solid propellants. Damping (Tan δ) of composite solid propellants was used to determine the shelf life of the samples based on the loss of half of the physical property Tan δ (50% drop in damping). For the air atmosphere, the calculated activation energy for the degradation reactions of the samples was 86.26 kJ·mol–1. Both models, Arrhenius and Berthelot, confirmed that the shelf lives of the samples under the nitrogen atmosphere are more than four times those in an air atmosphere.

This work focuses on the reprocessability of metallic 92Mo and ceramic MgO, which is under investigation for (Pu,MA)-oxide (MA = minor actinide) fuel within a metallic 92Mo matrix (CERMET) and a ceramic MgO matrix (CERCER). Magnesium oxide and molybdenum reference samples have been fabricated by powder metallurgy. The dissolution of the matrices was studied as a function of HNO3 concentration (1–7 mol/L) and temperature (25–90°C). The rate of dissolution of magnesium oxide and metallic molybdenum increased with temperature. While the MgO rate was independent of the acid concentration (1–7 mol/L), the rate of dissolution of Mo increased with acid concentration. However, the dissolution of Mo at high temperatures and nitric acid concentrations was accompanied by precipitation of MoO3. The extraction of uranium, americium, and europium in the presence of macro amounts of Mo and Mg was studied by three different extraction agents: tri-n-butylphosphate (TBP), N,N'-dimethyl-N,N'-dioctylhexylethoxymalonamide (DMDOHEMA), and N,N,N’,N’- -tetraoctyldiglycolamide (TODGA). With TBP no extraction of Mo and Mg occurred. Both matrix materials are partly extracted by DMDOHEMA. Magnesium is not extracted by TODGA (D < 0.1), but a weak extraction of Mo is observed at low Mo concentration.

W pracy przedstawiono analizę wpływu wielkości strumienia, składu i temperatury mieszaniny gazowej na efektywność cieplną skraplacza wężownicowego. Analizę przeprowadzono dla obszaru laminarnego przepływu gazu, w zakresie temperatur -30 do -10°C. Stwierdzono, że efektywność skraplacza wzrasta wraz ze wzrostem prędkości przepływu gazu oraz spadkiem temperatury. Sprawność ta jest większa, gdy mieszanina gazowa zawiera pary 2-propanolu i gdy w wężownicy zachodzi ich kondensacja.
The aim of this work was to investigate an influence of temperature, air flow rate and gas mixture composition on the effectiveness of coil heat exchanger. The studies were performed with air flow rate varying from 3 to 20 dm3/min (laminar flow range). Operating temperatures ranged from -30 to -10°C. The effectiveness increased with increasing air flow rate and decreasing operating temperature. This effectiveness was higher when gas mixture contained 2-propanol vapours condensing in the coil.

Opis:
In the world, inert materials are used to obtain high-strength concrete, the volume weight of which is quite large. We cannot get concrete with low thermal conductivity from such inert materials. Therefore, in order to obtain high-strength, environmentally friendly and energy- -efficient concrete, it was necessary to investigate local inert materials. The subject of research is natural zeolite and recycled ceramic waste, as well as polystyrene as an additive and micro-silica in cement mass to achieve penetrating waterproofing. The mentioned materials are obtained in Georgia in sufficient quantity, which allows us to produce energy-efficient concrete of high strength, low thermal conductivity, as well as sound and waterproofing. It is safe for both people and the environment. The correct mix will be provided by materials found in the local market, and the desired and low energy efficiency ensures the production of an environmentally friendly concrete.
