PROBLEM TO BE SOLVED: To provide a pulverized coal production system in a composite coal gasfication and power generation equipment used in a power station, etc., wherewith high cost, heat radiation loss, etc., otherwise unavoidable because of long main ducts, etc., for hot air and cold air for a mill, are inhibited and hence high economical effects and heat efficiency are obtd. SOLUTION: In a composite coal gasification and power generation equipment having a gas turbine 1, a waste heat recovery boiler 2, and a coal gasification oven, a coal pulverizing apparatus for drying and pulverizing coal with the waste heat to the gas turbine 1 is installed at the vicinity of the waste heat recovery boiler 2 and dried and pulverized coal is transported with an air steam to the vicinity of the coal gasification oven. Since the coal pulverizing apparatus and the waste heat recovery boiler are installed close to each other, the main hot air duct, etc., for a mill, i.e., the piping systems accompanying them, can be made short, thus enabling the heat radiation loss and cost to be reduced. |
