PURPOSE: To improve the power generating efficiency by working steam and oxygen to coal to manufacture combustible gas and using it for gas turbine generation, or reforming hydrocarbon by a reforming device by use of combustible gas and high temperature combustion gas to manufacture high purity hydrogen, and supplying it to a fuel cell to generate electricity. CONSTITUTION: Coal, steam and oxygen are supplied to a gas making furnace 1 to gasify the coal, the resulting combustible gas is passed to and treated by a reforming device 3 and a desulfurizing device 5 through a line 2, and then supplied to a combustor 7 constituting a gas turbine generating device by a line 6. The combustible gas is burnt under supply of compressed air, and the generated high temperature and high pressure combustion gas is introduced to a gas turbine 9, which is then rotated to drive a generator 23. The combustion waste gas leaving the gas turbine 9 is sent to a waste heat recovering boiler 11, a natural gas 16 is reformed by a reforming device 12 in the boiler 11, high purity hydrogen is generated by the action of a hydrogen separating penetrating film, and the resulting hydrogen is supplied to a fuel cell 19 to generate electricity. |
