Power generation device of coal firing turbine

The invention provides a combined cycle power generation system of a coal firing turbine; the system is suitable for the current energy situation of being rich in coal and insufficient in natural gas in our country; a power generation device of the coal firing turbine taking raw coal as fuel is developed by applying multiple new technologies such as pressurized pulverized coal spray combustion, plasma gasification ignition, classification type low-NOx combustion, and liquid dust melting separation slagging. The coal firing turbine is different from a conventional gas turbine, is an internal combustion type power machine which uses the fire coal to replace gas and enables energy of the fuel (the coal) to be converted into useful work, and can be used for generating electricity. The power generation device of the coal firing turbine is superior to an existing steam turbine generator unit, the utilization rate of the coal is increased, and the power generation cost is greatly reduced.
