The fork pipe type pulverized coal distributor has been installed for the coal pulverizing system of boiler equipped for ultra-supercritical 1 000 MW unit in one power plant
the said distributor has to undertake the task of distributing the pulverized coal from one mill to eight primary air burners.The performance of said distributor is closely related with the installation mode of said distributor and its coordinated pipeline system.By using fluent software
a numerical simulation of air and pulverized coal distribution has been carried out under condition of inlet section being 3D and the fork pipe being installed parallel and vertical to the elbow pipe
and the results of simulation and calculation being analysed and evaluated
providing theoritical support for designing combustion system of boilers.
