PURPOSE:To enable pulverized coal or the like to be used as fuel for a gas turbine, by melting the greater part of ashes in coal by means of a slagging combustor, and further by removing a small quantity of remaining ashes contained in combustion gas by means of a mist separator. CONSTITUTION:Air is introduced from an air intake port 8, and, after having been pressurized by an air compressor 9, is supplied from a compressed air takeout port 10 into a high-pressure air supply pipe 22. And a part of air is supplied from a swirling secondary air introducing port 13, a secondary air introducing port 14, and a ternary air introducing port 15 to a slagging combustor 1 and a mist separator outlet respectively. And the remaining air is used for transporting pulverized coal which is supplied via a pulverized coal bin 16 and a pulverized coal feeder 21, and is introduced into the slagging combustor 1 via a pulverized coal burner. Thus, the pulverized coal is burned by primary air and swirling secondary air, and the greater part thereof is exhausted into a slag reservoir 17. And the remaining ashes or the like are finally led to a mist-slag exhaust hopper 18.
