[57] [Abstract] [Problem] To provide high-efficiency power generation using boiler-only fuel such as inexpensive coal, heavy oil, plastic waste, and in some cases fuel for gas turbines. Is to generate power at low equipment costs with little adverse effect on the environment. SOLUTION: The boiler-specific combustion fuel is partially processed to be separated into a distillate and a residue, and a distillate is optionally added to the distillate with a fuel for a gas turbine and supplied to a gas turbine to generate power. The combustion exhaust gas is supplied to a boiler, and the remainder is burned by adding a boiler-specific fuel to the residue in some cases, and power is generated by the obtained steam. |
