Abstract
In this article, we address an urgent problem of solid waste management. We consider the possibility of applying gasification technology for municipal solid waste disposal at existing TPPs in St. Petersburg in order to produce thermal and electric energy. St. Petersburg Northern TPP-21, facing the problem of undercooling of the circulating water in the cooling towers, is proposed as a possible placement site. Using this water as a source of low-grade heat of a heat pump installation is considered as the possible solution to the problem. The study was carried out by calculating the thermal circuits in the Boiler Designer program, and calculating the heat pump in the Cool Pack program. The efficiency of the installation is achieved by increasing the supply of thermal energy and increasing the environmental friendliness of the installation by reducing thermal pollution. We have also calculated the limits of cost-effective heat pump application.
Highlights
According to the Federal State Statistics Service, in 2005, about 3 billion tons of waste was recorded on the territory of the Russian Federation, in 2015 the figure reached 5.06 billion tons, reaching 69% increase of waste in 10 years.The average volume of waste disposal in our country is only 35%, which leads to an increase in the volume of accumulated waste, and to a loss of up to 90% of useful products that are in demand on the market.Currently, 1.7 million tons of municipal solid waste (MSW) per year is generated as a result of the activities of the population, organizations and enterprises in St
Petersburg is processed at two specialized waste recycling plants (WRP), while the bulk of the solid waste is disposed at landfills without processing
With the transition to a closed heat supply scheme, the amount of make-up water will decrease by an order of magnitude, which significantly reduces the efficiency of using a heat pump

A small part of the solid waste generated in St. Petersburg is processed at two specialized waste recycling plants (WRP), while the bulk of the solid waste is disposed at landfills without processing
