Turbine room capable of automatically adjusting opening and closing conditions of air ports and control method thereof

Abstract

The invention discloses a turbine room capable of automatically adjusting opening and closing conditions of air ports and a control method thereof. The turbine room comprises a turbine room body, theturbine room body is provided with at least one air port and air port baffles, and further comprises a detection control module and a driving module. The air port baffles are correspondingly arrangedat the air ports, and the air port baffles can open or close the air ports. The detection control module is used for detecting operation data of the turbine room, and the driving module is electrically connected with the detection control module. The driving module is connected with the air port baffles, and the detection control module controls the driving module to drive the air port baffles tooperate so as to adjust the opening and closing conditions of the air ports. By controlling the air port baffles to adjust the opening and closing conditions of the air ports, the air inlet volume ofthe turbine room is controlled, heat loss of the turbine room is finally controlled, so that the purpose of maintaining the temperature stability in the turbine room is achieved, and a gas turbine isenabled to operate safely; and the turbine room capable of automatically adjusting opening and closing conditions of the air ports and the control method thereof have the advantages of simple design,easy implementation and small investment.

Description

technical field [0001] The invention relates to the field of gas turbines, in particular to a turbine room capable of automatically adjusting the opening and closing of tuyeres and a control method thereof. Background technique [0002] In the prior art, the turbine room in the gas turbine includes a turbine room body, a tuyere provided on the turbine room body, a corresponding tuyere baffle provided at the tuyere, an exhaust duct, and an exhaust fan arranged on the exhaust duct. The exhaust pipes communicate with the interior of the turbine room body and the outside respectively. The air pressure in the turbine room is lower than the atmospheric pressure by running the exhaust fan, and the external air enters the turbine room through the baffle, and then is drawn out of the turbine room by the exhaust fan, so that the air duct formed by the circulation can discharge the turbine room. The room heat is taken out of the plant to achieve the purpose of cooling the turbine room...

AI Technical Summary

Problems solved by technology

[0003] However, during the working process of the turbine room, the opening and closing of the tuyere baffle is fixed or manually adjusted, and cannot be adjusted in real time

After the turbine room works stably for a period of time, changes in the ambient temperature and gas turbine load will affect the temperature of the turbine room. When the ambient temperature is high and the gas turbine load is heavy, the temperature of the turbine room will rise to a higher value, or when the ambient temperature When the temperature is low and the load of the gas turbine is light, the temperature in the turbine room drops to a lower value. In both cases, the temperature in the turbine room cannot be kept stable under the condition that the air intake in the turbine room is the same.

Operation experience shows that: the temperature in the turbine room will affect the elevation of the bearing support of the gas turbine, thereby affecting the vibration change of the bearing during the operation of the gas turbine. If the temperature in the turbine room changes greatly, the vibration of the gas turbine bearing will become larger, and even affect the risk to safe operation
