Title: Experimental study and numerical simulation on the gas-solid two-phase flow field in the furnace of a 300 MW tangentially fired utility boiler

Abstract

To solve the high temperature corrosion and other fireside problems of a 300MW tangentially fired utility boiler burning meager coal, the experimental determination and numerical simulation of the gas-split two-phase flow field in the furnace were carried out by the authors. The experimental results and numerical simulation show that the use of large-angle same-direction deviating secondary air causes severe segregation of coal particles to the wall in and above the burner zone, and probably thereby forms reducing atmosphere in this region. And the use of counter-offsetting primary air, on the other hand, can form the general flow structure of air covering coal particles, thus reduce the chance of collision of coal particles to the water-wall, and therefore reduce the high temperature corrosion of the latter.
