Abstract
The utility model relates to a gas turbine facilities equipped reheat cycle power plant waste heat recovery unit. The field of technology is an electric power plant used reheat cycle power plant waste heat recovery unit. The outlet steam temperature of an over heater and a reheater is balanced, because the utility model employs the form that the over heater and the reheater are alternately set stone out. The utility model can operate even if the exhaust temperature of gas turbine is reduced or the gas turbine is operated under the under load level. The thermal efficiency is improvedm, and the rusty to steam turbine last stage, which is caused by wet steam, is avoided.
Description
Technical field
The utility model relates to a kind of power plant waste heat recovering device, the particularly a kind of residual heat of electric power plant of thermal cycle again recovering device that gas-turbine plant is housed.
Technical background
At present, heat recovery boiler is used in the heat recovery of power plant usually, this boiler is using existence can not change the problem of the Load Distribution difference in each superheater and reheater in the thermal cycle power plant again, and the temperature and pressure with steam maintains relatively difficulty of corresponding horizontal simultaneously.Goal of the invention
The purpose of this utility model is: a kind of residual heat of electric power plant of thermal cycle again recovering device that gas-turbine plant is housed is provided, the steam that produces in the superheater can be introduced high-pressure cylinder, the steam that produces in the reheater is introduced steam turbine, the thermal efficiency of gas turbine is improved.
Summary of the invention
The utility model is achieved in that a kind of residual heat of electric power plant of thermal cycle again recovering device that gas-turbine plant is housed, comprise by near to the secondary reheater that far is sequentially arranged on the combustion turbine exhaustion pipe, secondary superheater, the single reheat device, a superheater, economizer and be arranged on superheater and economizer between vaporizer, a described superheater links to each other with the admission end of secondary superheater with the high-pressure cylinder of steam turbine, single reheat device and secondary reheater are connected between the admission end of the steam output end of high-pressure cylinder and intermediate pressure cylinder, the steam output end of intermediate pressure cylinder links to each other with the admission end of low pressure (LP) cylinder, and the steam output end of low pressure (LP) cylinder is connected with condenser.
The utility model is owing to adopt the alternate form that is arranged in order with reheater of superheater, make the steam exit temperature balance in superheater and the reheater, even be lowered or gas turbine operation still can move during in low load levels in the delivery temperature of gas turbine, improved the thermal efficiency, avoided owing to of the corrosion of wet vapor cause to steam turbine last stage.
Embodiment
Below in conjunction with embodiment of the present utility model the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, compressor A links to each other with gas turbine C, from combustion chamber B gas driven combustion Gas-turbine and to load D work done, exhaust is E. The secondary reheater 2 that combustion turbine exhaustion pipe 1 is provided with, Secondary superheater 3, single reheat device 4, superheater 5, an economizer 6 and be arranged on superheater 5 No. one time And the vaporizer between the economizer 67. When gas turbine C load carrying, produce in the vaporizer 7 Steam flows to the high pressure cylinder F of steam turbine through superheater 5 and secondary superheater 3, after the steam work done Flow into intermediate pressure cylinder G and work done through single reheat device 4 and secondary reheater 2, steam enters low pressure (LP) cylinder at last H enters condenser and is condensed into liquid after the work done.
Claims (1)
1. the residual heat of electric power plant of thermal cycle again recovering device that gas-turbine plant is housed, it is characterized in that: comprise by near to the secondary reheater that far is sequentially arranged on the combustion turbine exhaustion pipe, secondary superheater, the single reheat device, a superheater, economizer and be arranged on superheater and economizer between vaporizer, a described superheater links to each other with the admission end of secondary superheater with the high-pressure cylinder of steam turbine, single reheat device and secondary reheater are connected between the admission end of the steam output end of high-pressure cylinder and intermediate pressure cylinder, the steam output end of intermediate pressure cylinder links to each other with the admission end of low pressure (LP) cylinder, and the steam output end of low pressure (LP) cylinder is connected with condenser.
