Abstract
The power plant according to the present invention improves the efficiency of conversion from thermal energy to electrical energy, and is provided with a first thermoelectric conversion element that generates electric power by using a difference in temperature between a temperature inside a boiler combustion chamber and a temperature of water supplied to the boiler from a feed water heater, and a second thermoelectric conversion element installed on the feed water heater that generates electric power by using a difference in temperature between a temperature of steam supplied from a turbine and the temperature of water supplied from a condenser.
Claims12
A power plant for generating power using the thermal energy of combustion gas or steam, in which thermoelectric conversion elements are provided at at least two locations having different temperatures.
A power plant comprising:
- a boiler that heats pressurized water in a combustion chamber to produce steam;
- a turbine connected to said boiler that generates electricity by a work of said steam;
- a condenser connected to said turbine that cools and condenses the steam emitted from said turbine;
- a feed water heater that preheats water supplied to said boiler from said condenser by using a part of said steam put to work in said turbine;
- a first thermoelectric conversion element installed around said combustion chamber of the boiler and that generates electric power by using a difference in temperature between a temperature of an interior of the combustion chamber and a temperature of the water exhausted from either said feed water heater or said condenser;
- and
- a second thermoelectric conversion element installed on said feed water heater and that generates electric power by using a difference in temperature between a temperature of the part of said steam supplied from said turbine and a temperature of said water supplied from said condenser.
A power plant having a plurality of steam turbines with different operating pressure ranges, the power plant comprising:
- a boiler that heats pressurized water inside a combustion chamber to generate steam;
- and
- a first thermoelectric conversion element installed around said combustion chamber of said boiler and that generates electric power by using a difference in temperature between a temperature of an interior of said combustion chamber and a temperature of either water or steam exhausted from any one of said steam turbines.
