DEVELOPMENT OF COGENERATION ENERGY SYSTEMS USING THE TECHNOLOGY OF GASIFICATION OF SOLID MUNICIPAL WASTE
THE PURPOSE. Development of energy-efficient schemes for the use of municipal solid waste as fuel in energy systems and complexes using continuous thermal processing technology. METHODS. Analysis of heat energy consumption for heat supply purposes in the region. Analysis of the possibility of replacing fossil fuels with existing heat supply sources through the use of solid municipal waste as fuel, including an assessment of the elemental analysis of raw materials and products of thermal conversion of MSW. Development of energy-efficient schemes for using MSW as fuel to provide thermal energy to consumers in existing energy systems. Mathematical modeling of the plant operation using MSW as fuel. RESULTS. Energy-efficient schemes for using MSW as fuel in existing energy systems using MSW gasification technology have been developed, and the relevant schemes have been evaluated according to energy, environmental and economic indicators. The substantiation of the possibility of partial substitution of fossil fuels through the use of MSW in the production of thermal energy has been carried out. The comparison of existing and promising methods of energy utilization of MSW with the identification of advantages and disadvantages of each of the alternative solutions is carried out. In the course of experimental studies on heating a characteristic mixture of MSW in a furnace with the measurement of the mass of the image, data on the yield of volatile, ash content and the amount of bound carbon in the material were obtained. In the mode of computer simulation using the Aspen Plus software package, an assessment of the qualitative and quantitative composition of the gas obtained during thermal processing of MSW was carried out. Energy-efficient schemes based on MSW gasification using gas turbine equipment and their integration into existing energy systems have been developed. The construction of the material and thermal balance of the installation based on a gas turbine engine with an assessment of their energy efficiency was carried out. The selection of the main power equipment, which can be used for the implementation of the developed schemes based on the gasification of MSW, has been carried out. CONCLUSION. The results obtained allow us to evaluate the prospects for the introduction of a MSW gasification plant based on a city boiler house with subsequent generation of thermal and electric energy in a cogeneration scheme in terms of efficiency and payback.
