Abstract

The paper presents the method and results for technical and economical study of a cogeneration plant with exhauster gas turbines fueled by solid fuel. The search of fundamental regularities of the processes allowed us to recommend optimal parameters for different variants of power plant operation and formulate recommendations for optimal configuration of a cogeneration plant with EGT.
