The invention relates to a fuel gas and steam combined cycle unit structure and an arranging method. The fuel gas steam combined cycle unit structure comprises an upper layer workshop and a lower layer workshop, a gas turbine and a gas turbine generator are mounted in the lower layer workshop, the upper layer workshop comprises a left workshop and a right workshop, a steam turbine, a steam turbinegenerator and a waste heat boiler equipment auxiliary room are mounted in the left workshop, and a waste heat boiler is mounted in the right workshop. According to the fuel gas and steam combined cycle unit structure, the total volume of the workshops can be reduced, the distance between the steam turbine and the waste heat boiler can be shortened, the length of a steam and water pipeline connected with the steam turbine and the waste heat boiler can be effectively reduced, particularly, the length of an expensive high-temperature high-pressure steam pipeline in a steam pipeline system can bereduced, and initial investment can be reduced. According to the fuel gas and steam combined cycle unit structure and the arranging method, the pipeline length is reduced, therefore, the pressure drop and cooling losses of the pipeline system can be effectively reduced, and unit hot economy can be improved.
Description
technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a structure and arrangement method of a gas-steam combined cycle unit. Background technique [0002] The operation mode of the gas-steam combined cycle unit is that the gas turbine drives the steam turbine to run, and the exhaust gas of the gas turbine is discharged into the waste heat boiler, and the high-temperature and high-pressure steam generated drives the steam turbine, which drives the steam turbine to generate electricity. [0003] At present, the domestic gas-steam combined cycle unit main plant layout plan is generally arranged in several modules: gas turbine generator unit module, steam turbine generator unit module, and waste heat boiler island module. According to the current requirements for environmental protection and noise reduction, the waste heat boiler feed water pump is equipped with an independent factory building, which is generally arra...
