Abstract
Taking a 300 MW oxy-coal fired boiler unit as the research object,the integrated modular modeling system (IMMS) was applied to establish the dynamic simulation model for the whole unit.Under the BMCR condition,the effects of coal feeder speed and primary recirculation fan damper opening degree on the combustion and flue gas systems of the boiler were analyzed.The results show that,the coal feeder speed disturbance has great direct influence on flue gas flow and heat transfer in the combustion and flue gas system,it also has a certain effect on the parameters of the flue gas and steam.Factors such as the primary recirculation fan damper opening disturbance,the secondary recirculation fan speed disturbance and the compressor speed disturbance mainly affect the flue gas flow,and then affect the heat transfer of the unit,while they have relatively weak influence on the steam parameters.关键词
