Opis:
Nitrogen oxide conversion to nitrogen over Pt/Al2O3, Pd/Al2O3, Rh/Al2O3 catalysts was investigated. The results of the catalytic activity investigations, with the iso-x method, showed that NO reduction by methane occurs at a reasonable rate at the temperature range 200-500°C. Alumina-supported Pd, Pt and Rh catalysts have been compared for the selective reduction of NO to N2. All the catalysts showed good activity in NO reduction by methane, giving around 80 - 90% N2 production. At moderate temperatures Pt is the most active catalyst for the removal of NO.

Opis:
Spectral remote sensing is a very popular method in atmospheric monitoring. The paper presents an approach that involves mid-infrared spectral measurements of combustion processes. The dominant feature in this spectral range is CO2 radiation, which is used to determine the maximum temperature of nonluminous flames. Efforts are also made to determine the temperature profile of hot CO2, but they are limited to the laboratory conditions. The paper presents an analysis of the radiation spectrum of a non-uniform-temperature gas environment using a radiative transfer equation. Particularly important are the presented experimental measurements of various stages of the combustion process. They allow for a qualitative description of the physical phenomena involved in the process and therefore permit diagnostics. The next step is determination of a non-uniform-temperature profile based on the spectral radiation intensity with the 8 m optical path length.

Opis:
Experimental results of combusting three different syngases in an internal combustion (IC) spark ignition engine are presented in this paper. The syngases used for tests varied each from the other with hydrogen content, which was of 10,15 and 60%. Other combustible gases as CO and CH4 were also changed. Thus, the lower heating value of the syngases was of 2.7, 4.6 and 17.2 MJ/nm3, respectively. Combustion tests were performed at stoichiometric ratio of syngas-air mixture, with variable spark timing and constant compression ratio of 10. On the basis of in-cylinder combustion pressure histories the indicated mean effective pressure (IMEP) was computed and presented versus spark timing and vs location of the middle combustion phase expressed by the 50% of mass fraction burned (MFB). Additionally, the 0-10% MFB and 10-90% MFB were also determined. Furthermore, the paper contains theoretical determination of the three fuel quantities, which can affect combustion duration and heat release rate during burning the syngases in the IC engine. They are as follows: laminar flame speed, ignition delay and adiabatic flame temperature. Final results does not show satisfactory correlation between LFS computed at NTP and real combustion phasing. Furthermore, both long combustion duration and long 0-10% MFB leading to unstable combustion were observed for the syngas with the lowest LHV of 2.7 MJ/nm3.

Opis:
Bag-house dust collectors are commonly used in the industry for removing solid particles from dust laden gas. Bag house filter media need to be periodically cleaned in order to remove accumulated particles from the filter surface. Pulse jet cleaning is the most common cleaning method but produces noise increment of about 30-40 dB, which is its major disadvantage. The present study reports on a new type of combined wet scrubber-Venturi scrubber in the shape of a cyclone. The proposed design eliminates the noise associated with the pulse jet filter-cleaning process and filter bag replacement costs. The experimental results were demonstrated with high efficiency in the design.

Opis:
An important issue in construction of combustion chamber in compression-ignition engines is proper selection of its shape and size. Both features are dependent on several factors such as fuel injector location and angle, spray atomizer selection (amount of holes, their diameter and angular position), location of inlet valve and air turbulence. By doing research on prototype engine T370, an analysis of influence of combustion chamber size and its modifications going towards lip construction on flue gas toxicity was done. The diameter and depth of combustion chamber was being changed while maintaining the same compression ratio. After that, a modification of tested combustion chambers was made by creating so called “lip”, which aim was to create a swirl of injected fuel in the vertical plane. To visualize the changes in swirl, a numerical analysis of fuel injection into combustion chamber was made. In discussed study, emission tests were performed according to ECE-R49. During the research six combustion chambers with diameters 60, 63 and 66 mm (and their modification) were investigated. Tests were performed for several types of injectors and different injection timing. However, for analysis of combustion chamber size the results are presented for the same injectors but with optimized injection timing.

Opis:
In this work non-combustible gases impact on combustion processes studies is performed. Research was performed in a optically accessible rapid compression machine (RCM) under spark ignition engine conditions. The distribution of the swirl charge in the relation to adopted for analysis sequence of gas delivery to the chamber was varied with regard to the main injection. Authors investigate the influence of these sequence on the combustion and the ignition delay of the main injection and the overall combustion characteristics. The aim of this work is the experimental recognition of possibilities of creating combustible mixtures of light hydrocarbon fuels surrounded by non-combustible gases affecting the function of the inhibitor. Specifying the ability of preparation and combustion of mixtures in such systems enables the scientifl analysis of adiabatization of the combustion process of fuel-air mixtures in the operating chambers. Theoretical analysis of the issues indicates possibility of obtaining such a stratification of the charge, that the inactive exhaust gases creating the outer ring surround the combustible mixture inside in such a way as to reduce the amount of heat exchanged between the working medium and the walls of the cylinder.

Opis:
Internal combustion engines have seen a reduction of the dynamics of their efficiency growth in recent years. All kinds of new modifications and changes introduced in this field can only manage changes of engine efficiency at the level of a fraction of a percent. Considering the concept of unification of SI and CI internal combustion engine structures, one can expect to see their efficiency increase by the reduction of losses, whose causes and occurrence is commonly known. The improvement of the combustion system is mainly related to the reduction of thermal losses generated in this process. Therefore, the current issue is the advanced analysis of any possibilities of improving the combustion conditions and more fully understanding the processes that accompany them. The authors of the article see such a possibility in the conceptual control of the combustion process, which aims to obtain a combustible mixture surrounded by nonflammable gases. This way the flame contact with the cylinder walls is limited, which should in turn contribute to reducing the heat exchange with the walls. This research is a continuation of previous research work; current work focuses on determining the actual distribution of gases in the combustion chamber using the advanced shadow photography method. The article specifies the effect of nonflammable gas injection pressure increase on the area of the boundary layer formed between the non-flammable gases and cylinder walls.

Opis:
The subject of this work was the investigation of zeolite as a sorbent of toxic gases. In Nizny Hrabovec in the Slovak republic, two layers of zeolite with the active component clinoptilolite can be found. The study presented here investigated the ability of this natural zeolite to reduce polycyclic aromatic hydrocarbons (PAH) and NO emissions from engine exhaust. Exhaust gases from combustion engines include toxic components such as carbon monoxide, nitrogen oxides and hydrocarbons. Polycyclic aromatic hydrocarbons (PAH) are a component of hydrocarbons causing harmful influence on life forms. The experiments focused on the potential reduction of these toxic gases based on the sorption and catalytic properties of natural zeolite. Also observed was the influence of chemical adjustment including incorporation of certain metal elements. Chemical analysis by mutually independent technologies served to observe the sorption of PAH with carcinogenic properties on the natural zeolite tested. The experiments showed that chemical modification improved the sorption and catalytic properties of natural zeolite. The PAH were analysed in an extract of the contaminated, thermally-activated natural zeolite and modified zeolite after washing with ammonium chloride, cobalt chloride and copper sulphate. The study also presents results of NO measurements obtained by testing the filter-sorptive automobile system.
Przedmiotem niniejszej pracy było zbadanie zeolitu jako sorbentu toksycznych gazów. Wystąpienia dwóch warstw zeolitu zawierających wtrącenia aktywnego klinoptylitu można spotkać w okolicach Nižnego Hrabovca w Republice Słowackiej. Przedstawione badania dotyczą zdolności tego naturalnego zeolitu do redukcji wielopierścieniowych węglowodorów aromatycznych (WWA) i redukcji emisji tlenków azotu z układu wydechowego silnika. Gazy wydechowe z silników spalinowych zawierają toksyczne składniki, takie jak tlenek węgla, tlenki azotu i węglowodory. Wielopierścieniowe węglowodory aromatyczne (WWA) wywierają szkodliwy wpływ na zdrowie istot żywych. Wykonane eksperymenty koncentrowały się na ocenie potencjalnej redukcji tych toksycznych gazów poprzez sorpcję i właściwości katalityczne naturalnego zeolitu. Obserwowano także możliwości korekty procesu chemicznego, w tym poprzez zastosowanie niektórych związków pierwiastków metalicznych. Prowadzone analizy chemiczne z wykorzystaniem niezależnych technologii miały na celu obserwację sorpcji WWA o kancerogennych właściwościach na testowanym naturalnym zeolicie. Doświadczenia wykazały, że chemiczna modyfikacja poprawia właściwości sorpcyjne i katalityczne natualnego zeolitu. Analizowano WWA w zanieczyszczonym, termicznie aktywowanym naturalnym zeolicie oraz w modyfikowanym zeolicie powstałym po jego przepłukaniu w chlorku amonu, chlorku kobaltu i siarczanie miedzi. W pracy przedstawiono również wyniki pomiarów NO uzyskanych z badań filtra sorpcyjnego samochodu.

The primary methods of reducing nitrogen oxides, despite the development of more advanced technologies, will continue to be the basis for NOx reduction. This paper presents the results of multivariate numerical studies on the impact of air staging on the flue gas temperature and composition, as well as on NOx emissions in a OP 230 boiler furnace. A numerical model of the furnace and the platen superheater was validated based on measurements using a 0-dimensional model of the boiler. Numerical simulations were performed using the ANSYS Workbench package. It is shown that changes in the distribution of air to OFA nozzles, the angle of the air outflow from the nozzles and the nozzle location involve a change in the flue gas temperature and in the volume of NOx and CO emissions at the furnace outlet.

The aim of the present study was a numerical investigation of the efficiency of the combustion process of a novel concept burner under different operating conditions. The design of the burner was a part of the development process of a complete SOFC based system and a challenging combination of technical requirements to be fulfilled. A Computational Fluid Dynamics model of a non-premixed burner was used to simulate combustion of exhaust gases from the anode region of Solid Oxide Fuel Cell stacks. The species concentrations of the exhaust gases were compared with experimental data and a satisfactory agreement of the conversion of hydrocarbons was obtained. This validates the numerical methodology and also proves applicability of the developed approach that quantitatively characterized the interaction between the exhaust gases and burner geometry for proper combustion modelling. Thus, the proposed CFD approach can be safely used for further numerical optimisation of the burner design.

Natural and synthetic zeolites have been the subject of worldwide scientific research for several decades. Increased attention is paid to utilization of zeolites in environmental protection. The interest in zeolites is related to their unique structure and the related chemical and physical properties which form the basis of their potential ecological, industrial and agricultural applications. The paper presents partial results of research focused on the use of natural zeolite clinoptilolite for reduction of nitrogen monoxide, the component of combustion engines exhaust gases. Experiments were carried out with natural zeolite and also its modified forms. The results obtained allowed us to state that clinoptilolite is a prospective material for application in the treatment of exhaust gasses from combustion engines.

The fuel injection phenomena belongs to the most essential processes, which are object of many experimental and theoretical works, indispensable for development of contemporary internal-combustion engines, both the spark and compression ignition. The direct injection of fotel to the engine combustion chamber belongs to most advanced solutions and must realize at least two or even more different strategies of engine performance. Article presents the various research methods of the fuel atomization processes, being concentrated on laser methods, from which deserves on the emphasis the Particle Image Velocimetry (PIV) system, the Laser Doppler Velocimeter (LDV) system and Phase Doppler Particle Analyzer (PDPA) system. Article presents theoretical analysis relating the atomized fuel stream. The results of research based on the laser research equipment are also submitted in the article. Moreover presented are the results ofresearch of the combustion process in the fixed volume chamber, where essentially two different strategies of the combustion process of homogenous and heterogeneous load were realized. The properly shaped fuel stream permits on obtainment of repeatable ignition and combustion in the wide range of the mixture variance. The essential meaning has the fuel stream disintegration, which influences advantageously on the level of the toxic exhaust elements emission, particularly on the hydrocarbon emission level because of the ignition dropout elimination and on the level of the nitrogen oxides emission because of short sojourn time of the fuel droplets in the combustion zone.

Opis:
This work is the third part of the articles published on the effects of the shape and position of the combustion chamber in piston compression diesel engines on the toxicity of exhaust gases. In two previous articles presented at the KONES 2015 conference, the impact of position of the combustion chamber in relation to position of the injector, and the influence of the shape of the chamber (diameter, depth, lip on the CO, HC and NOx emissions was analysed. In the current article, the shape of the “central body” in a combustion chamber is analysed. “Central body” is the protrusion located in the central part of a toroidal combustion chamber. Subsequent modifications to the basic combustion chamber consisted of reducing the size of this protrusion. The study involved four versions of combustion chambers. Modifications caused a slight decrease in the compression ratio, which could have an impact on the unambiguousness of the results, as the effect of changes in shape of the “central body”. However, to maintain a constant compression ratio would require a change in diameter or depth of the chamber cavity, which would obscure the obtained results with even greater impact. Emission tests in discussed study were performed according to ECE-R4. During the tests, the completion of the engine and the engine settings were not changed.
