Description

technical field

[0001] The invention relates to the technical field of thermal power generation, in particular to an optimization method for an overall rubber ball system and a flow field structure of a rubber ball collecting net. Background technique

[0002] In modern thermal power plants, the energy loss of the cold-end system is a very prominent problem. To accelerate the energy saving and emission reduction of existing units, we can start from the cold-end system. As the core of the cold end system of the thermal power station, the condenser is the hub connecting the exhaust port of the steam turbine and the circulating water system. The task of the cold end system is to discharge the waste heat of the system in a timely manner. If there is a problem in the heat release process, the exhaust pressure of the steam turbine will increase, the work will decrease, and the thermal efficiency of the cycle will decrease. In the wet season, because the water contains a lot of si...
