Patent ID: 7318316

Claim:
A thermal power plant (A) using a reheating-and-regenerating type Rankine cycle comprising: a superheat conduction pipe ( 3 a ) provided to produce a main steam ( 4 ) with high pressure and high temperature to transfer said main steam ( 4 ) to a high pressure turbine ( 5 ); a reheat conduction pipe ( 7 a ) is installed in a boiler ( 1 ) to reheat a steam produced by said high pressure turbine ( 5 ) to provide a reheat steam ( 8 ) which is to be supplied to a medium pressure turbine ( 9 ) and a low pressure turbine ( 10 ); an evaporation heat conduction pipe provided to be heated by burning a fossil fuel; an electric generator ( 11 ) driven by each of the turbines ( 5 , 9 , 10 ) to generate an electricity; a condenser unit ( 13 ) provided to form a condensed water from an exit steam which said low pressure turbine ( 10 ) exhausts; a feed water path (W) through which the condensed water passes to said evaporation heat conduction pipe of said boiler ( 1 ); said feed water path (W) providing a low pressure feed water heater ( 16 ), a medium pressure feed water heater ( 20 ) and a high pressure feed water heater ( 22 ) to which a low pressure bleed ( 17 ), a medium pressure bleed ( 21 ) and a high pressure bleed ( 23 ) are in turn supplied from the respective turbines ( 10 , 9 , 5 ); a feed water bypass (BW) provided independent of said feed water path (w) to join a condensed water ( 14 ) flowed out of the condenser unit ( 13 ) and feed waters ( 18 - 1 , 18 - 2 , 18 - 3 ) each flowed out of the respective feed water heaters ( 16 , 20 , 22 ) so as to form confluent feed waters (Wg), said confluent feed waters (Wg) being transferred to said evaporation heat conduction pipe through a heat exchanger conduction pipe ( 29 a ) which is provided with a heat exchanger ( 29 ); whereby a huge amount of combustible wastes incinerated in a large incineration plant ( 27 ) produces a high temperature fluid ( 28 ) which passes through said heat exchanger ( 29 ) to form an incineration plant drain ( 30 ) which is returned to said large incineration plant ( 27 ) by means of an incineration drain pump ( 31 ).
