Denitration inlet smoke temperature control system and method

The invention discloses a denitration inlet flue gas temperature control system and method, relates to the technical field of flue gas denitration, and can solve the technical problem of how to control the temperature of denitration inlet flue gas to meet the denitration temperature requirement. The system comprises a main path flue gas opening degree adjusting module, a bypass flue gas opening degree adjusting module and a denitration inlet flue gas temperature monitoring module, the denitration inlet smoke temperature monitoring module is connected with the main path smoke opening degree adjusting module and the bypass smoke opening degree adjusting module and used for monitoring the actual smoke temperature of a denitration inlet in real time and sending the actual smoke temperature of the denitration inlet to the main path smoke opening degree adjusting module and the bypass smoke opening degree adjusting module in real time. When the actual smoke temperature of the denitration inlet is different from the
