| Abstract: | Heat absorption capacity of circulating fluidized bed(CFB) boiler was related to flame temperature and bed suspension density,while bed suspension density could be replaces by the flame emissivity.Based on the real-time and rapidity of image processing,an online prediction model of boiler heat absorption capacity was presented.The mathematical model of heat absorption capacity with flame temperature and emissivity was established.The flame temperature and emissivity could be calculated from the flame radiat... |
