ABSTRACT:
An improved coal fired gas turbine having an enhanced working efficiency and a relatively low manufacturing cost is disclosed, in which a coal-fired furnace, a mist separator, a gas turbine section and an air compressor are sequentially disposed. The gas turbine section and the air compressor are connected by a common shaft with a partition interposed therebetween so that direct communication of gas and air therebetween is prevented. The coal-fired furnace is constructed as a slagging combustor having a heavy thermal load. A molten slag extraction device is provided at the middle portion of the combustor. Air introducing holes communicate with an outlet of the air compressor for controlling the combustion gas. Furthermore, a mist separator for removing ash mist in the combustion gas is provided on the downstream side of the coal-fired furnace, and a combustion gas introducing section of the gas turbine is provided on the downstream side of the mist separator.
