Experimental Study on Performance of Undergroud Coal Gasification and Power Generation System

摘要

With the development of underground coal gasification technology, the field experiments of underground coal gasification are undertaken successfully in two coalmines of Xinwen mines group as well as underground coal gasification and power generation using internal combustion engine units with rated capacity of 400kW. In the paper, the underground coal gasification and power generation system including the gas cleaning system is analysed, and on the basis of field operation, the system and operation parameters are optimised to guarantee the stable and economical operation, which provides reference for the propagation of this kind of energy utilizing system.
