Problems solved by technology

[0018] The HAT cycle can make full use of medium and low temperature waste heat, which greatly improves the efficiency of the system. However, because the conventional HAT cycle adopts the internal combustion method, it needs to burn oil and gas fuel instead of coal, and the combustion products are polluting emissions. The water vapor in it Difficult to recycle

Description

technical field [0001] The invention relates to a novel external combustion and recyclable water wet air gas turbine circulation system and a method thereof which combine the external combustion gas turbine technology and the wet air turbine technology. technical background [0002] At present, technologies related to the present invention mainly include external combustion gas turbine combined cycle technology (EFCC) and humid air turbine (HAT) power generation technology, and the development status and system characteristics of their respective technologies are as follows. 1. External combustion gas turbine combined cycle technology (EFCC) [0003] Indirect combustion gas turbine power plants have been proposed since the 1930s. In 1945, Keller made a summary; in the cycle discussed by Mordell in 1950, the exhaust gas of the air turbine was used as combustion air, and the heat supplied to the gas turbine was obtained through solid fuel combustion; The operation of six coa...
