To provide garbage burning power generation equipment wherein quantity by incinerating waste is largely reduced, generation and re-synthesis of dioxin is effectively restrained by effectively decomposing an organic chlorine compound in combustion exhaust gas, even dioxin remaining in incineration ash is decomposed, there is no possibility of re-elution, an energy loss is reduced, and heat efficiency and energy saving are enhanced.

This garbage burning generation equipment has a kiln furnace 11 for heating the incineration ash to a melting point or more by incinerating the waste, a kiln secondary furnace 12 for reheating the exhaust gas to a high temperature, an exhaust heat recovering boiler 16 for generating steam by quickly cooling the exhaust gas, a bag filter 14 for collecting and removing a reaction product by blowing alkali powder in the gas, and a gas turbine generation set 18. The combustion exhaust gas of a gas turbine is supplied to the kiln furnace 11 and the kiln secondary furnace 12 as combustion air, and generating steam of the exhaust heat recovering boiler is injected as steam into a combustor of the gas turbine.
