| titleOfInvention | SNCR control system based on CFB boiler NOx emission concentration prediction |
| abstract | The utility model relates to a SNCR control system based on CFB boiler NOx emission concentration prediction, which belongs to the technical field of intelligent power generation and comprises an external hanging server, a DCS and a communication system; an intelligent prediction system is embedded in the plug-in server, and the plug-in server is connected with the DCS through a communication system; the intelligent prediction system inputs numerical values into a PID controller, the PID controller outputs action signals to an ammonia water pump manual operator, and the ammonia water pump manual operator controls a variable-frequency ammonia water pump to send ammonia water into an SNCR (selective non catalytic reduction) denitration device. The utility model controls the ammonia pump manual operator through the PID controller, and further controls the variable frequency ammonia pump to send ammonia water into the SNCR denitration device; the PID controller receives the numerical value of the NOx emission concentration predicted by the intelligent prediction system, so that the numerical value can be moved in advance, and the delay caused by the traditional dependence on field measurement is overcome; the intelligent prediction system is embedded into an LSTM neural network with memory and forgetting functions, so that the prediction precision is high, and prediction can be carried out 3 minutes in advance. |
