Increment of Furnance Exit Gas Temperature for Monitoring Ash Fouling in the Furnace of Coal-fired Boilers

XU Xiaohu,ZHOU Keyi,WEI Hongqi,XU Jianqun(School of Energy & Environment,Southeast University,Nanjing 210096,Jiangsu Province,China)  
By Applying nonlinear incremental analysis methods,the extent of ash fouling in furnace was represented by the increment of furnace exit gas temperature(I-FEGT) between two states: actual running state and designing state.And the mathematical model for I-FEGT was also established.For validating in respect of accuracy,some calculations were carried on in simulation mode.Using the real time data of a coal-fired utility boiler in 600 MW power plant,I-FEGT was calculated for on-line monitoring the varieties of ash fouling in furnace.The results indicate that,I-FEGT correctly reflects the extent and varieties of ash fouling in furnace,can be used for furnace ash fouling monitoring,real-time guidance or checking effect for soot-blowing.
