Coal-fired boiler combustion dynamic field rapid calculation and real-time display system and calculation method

The invention discloses a coal-fired boiler combustion dynamic field rapid calculation and real-time display system and a calculation method. The system comprises a DCS data processing module, a CFD (computational fluid mechanics) database module, a prediction calculation module and a combustion display module. Through combination of a neural network and CFD numerical value simulation, in-furnacethree-dimensional combustion power fields at continuous any working condition points are calculated rapidly from in-furnace three-dimensional combustion power field data at discrete limited working condition points, and the in-furnace combustion situations are displayed in various forms. By the coal-fired boiler combustion dynamic field rapid calculation and real-time display system and the calculation method, operators of a power plant can know the in-furnace combustion situations under the various working conditions intuitively and rapidly, influence on combustion by various factors is comprehensively evaluated and
