Complex analysis of the efficiency of plants for the thermochemical conversion of solid fuel

The results of an analytical study of the thermodynamic and economic efficiency of power-engineering plants, which use the steam–oxygen gasification of coal as a head-end process, are presented. The target products of gasification are synthesis gas and electrical and thermal energy. The study was based on a systems test procedure in heat-power engineering, which makes it possible to determine the expediency and timeliness of this technology with consideration for the forward fuel–energy balance of the country and foreign-economic factors. The rational areas of the applicability of the proposed plant were determined.
