Gas turbine power generation equipment

Abstract

The invention discloses gas turbine power generation equipment. The gas turbine power generation equipment comprises a gas turbine box arranged in a generator body, wherein a gas turbine cavity is arranged in the gas turbine box, and an air inlet with an opening facing left is formed in the left side of the gas turbine cavity. According to the gas turbine power generation equipment, the transmission connection between a main shaft and a generator shaft is realized through the meshing transmission between gears, so that a gas turbine and a generator are effectively connected; meanwhile, by utilizing the meshing between the gears and racks, the main shaft and the generator shaft are connected to drive the generator shaft to rotate to generate current while fuel oil enters into a combustion chamber of the gas turbine to combust to generate gas to drive the main shaft to rotate; and an air pump is started by part of electric energy generated through wires, so that air is circulated among components in a generator cavity, the purpose of cooling and temperature reduction is realized, and the condition that the mechanical performance of a machine is affected by working at high temperatureis effectively prevented.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a gas turbine power generation equipment. Background technique [0002] During the combustion process of the gas turbine, the main shaft of the gas turbine needs to idle for a period of time while the fuel is burning to connect the generator shaft to the main shaft to ensure that there is enough energy to drive the generator shaft to rotate, which increases the fuel consumption required for power generation , and the generator shaft and the main shaft are connected by a coupling. If the coupling is damaged, the power generation process will be stopped and the power generation efficiency will be reduced. The gas turbine and generator will emit a lot of heat during operation and need to be stopped irregularly The operation achieves the purpose of heat dissipation, thereby reducing the power generation efficiency. Contents of the invention [0003] The object of the pres...
