TASCFLOW-CFX/COALFIRE software is a technical cooperation project between China and the Government of Canada , the joint development of large-scale pulverized coal boiler furnace numerical simulation software . This is the first application of the software is calculated based on a 300MW four corners tangentially fired boiler the ten operating conditions the exact numerical results . The analysis run adjustment of boiler combustion coal-fired qualitative changes , changes in coal fineness , boiler load changes , changes in the way of the secondary air with the wind , put into operation of the burner change the impact of the law on the simulation results . While a the Coal Ignition stable ignition and burnout characteristics furnace exit gas temperature deviation and Slagging distribution . And to find out the optimal conditions , so as to guide the adjustment and optimization of the combustion conditions . Provide a model training sample pulverized coal power plant boiler combustion conditions online monitoring and optimization systems , and system modeling have been tested.
