NOxemission and boiler efficiency model is the foundation of boiler combustion optimization.The weighted least squares support vector machine(WLS-SVM)was employed to establish the NOx emission model.By combining the WLS-SVM with sequential forward selection(SFS)
the boiler efficiency model was built.Moreover
on the premise of not affecting the model accuracy
the redundancy compositions in the model was reduced
which simplifies the model structure and enhances the calculation speed.On the basis of the established models
an optimization method which can effectively balance the boiler efficiency and NOxemissions was put forward
by applying the genetic algorithm.The results show that this optimization program improved the boiler efficiency and NOxemission by 0.386%and 99.147mg/m3 on average
