SOLID WASTE AS A FUEL FOR BOILERS OF THERMAL POWER PLANTS

This article investigates the combustion of solid waste in thermal power plants. The article describes the current use of gasification for waste processing and its use in thermal power plants. The review revealed the problem of waste accumulation and the complexity of developing a scheme for its processing. In this regard, the authors propose a technology for recycling waste at thermal power plants with the subsequent production of thermal and electrical energy. For the study, the types of raw materials (waste) were selected in accordance with the Rostov territorial waste management plan, which judges husk and sunflower meal waste to make the greatest energy contribution. The calculation of the thermal and the exergetic balance of the TPP-210A boiler for certain types of waste was also carried out. Graphs were constructed comparing the synthesis gas from the selected waste with natural gas and coal, as well as diagrams of exergy flows for the selected waste, natural gas, and coal. The authors showed that the gasification of solid household and agricultural waste can increase the thermal and exergetic efficiency of the boiler and replace coal and natural gas, reducing the environmental impact. Calculations of the energy and exergetic balances show the efficiency of using solid household and agricultural waste for incineration at thermal power plants, in particular, based on the thermal and exergetic efficiency of the boiler, depending on the fuel used.
