Description

Drainage system for 300MW grade F-grade heavy-duty gas turbine body
Technical Field
The utility model relates to the technical field of gas turbines, in particular to a drainage system for a 300MW grade F-grade heavy-duty gas turbine body.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
After the gas turbine is stopped for a long time, due to the fact that the moisture content of air or flue gas is large, condensate water can be generated; water accumulation may also occur when the gas turbine is water washed. The accumulated water of the gas turbine can cause serious threat to the safe operation of the gas turbine, and in order to solve the problems, the heavy gas turbine is required to be provided with a drainage system to drain the accumulated water in the air pipelines of the gas compressor, the combustion chamber, the turbine and the body.
