Kuris Y. Тhe rise of heat engineering and ecology index of biogas burning in the heat generation equipment

The dissertation work is devoted to work out the technology of power usage of biogas, received as a result of anaerobic fermentation of biomass with the purpose of reducing fossils fuels consumption and greenhouse gazes emission. The analysis of power biomass usage tech-nologies in Ukraine has been made, the ways of solution of ecological problem greenhouse effect emergence and climate change connected with it have been formulated. The experimental testing grounds on base of water-heating boilers of 7 and 730 kWt are designed and manufactured in conditions of cattle-breeding complex of the Open Joint Company "Zaporizhstal". The power and ecological experimental researches of biogas burning both in pure and in different mixture proportions with the natural gas have been held. During the experiment and treatment of data received the experience of heat-engineering experiment was used, which secures the reliability of data received. It has been determined, that the heat calculations of industry boilers according to the normative method result in making heat ex-change in heating boiler less intensive, accordingly the necessary amendments have been suggested. The comparison of digital and physi-cal experiments results has revealed that the normative method for cal-culation of domestic water-heating boilers with low power on natural gas and biogas in inadequate. For steel water-heating horizontal two-runing heatpipe boilers with the power 350…750 kWt, which work on gas fuel with furnace working loat 0.58…1 MWt/m3, the amendments to norma-tive method have been suggested. There has been worked out the ecological criterium which al-lows the objective comparison between bioenergy technology irrespec-tive of the kind and the quality of fuel changed. The analysis of reduction of greenhouse gazes emission into the atmosphere at the complete or portial change of fossils fuels for biogas has been presented.
