PURPOSE:To improve the efficiency of waste heat recovery by connecting the high pressure vapor feed pipe of a waste heat recovery boiler to the high pressure portion of a turbine, the hot water feed pipe of a hot water generator by low temperature waste heat to a low pressure flusher, and the vapor feed pipe of the flusher to the intermediate stage of the turbine. CONSTITUTION:High temperature waste heat is recovered by a waste heat recovery boiler 11 to generate high pressure vapor, which is introduced into the high pressure portion H of a steam turbine 15. Low temperature waste heat 19 is recovered by a hot water generator 12 to generate pressure hot water, which is decompressed by a control valve 13 to generate low pressure vapor at a flusher 14, then the low pressure vapor is introduced into the intermediate stage M of the steam turbine 15. The high pressure vapor works at the high pressure portion H of the steam turbine 15, and this vapor is combined with the low pressure vapor from the flusher 14 to drive the low pressure portion of the steam turbine 15 and generate electricity. That is, waste heat can be efficiently recovered for a plurality of waste heat sources with different temperature levels. |
