【Abstract】 For six corners tangentially fired boiler, gas flow tangential circle characteristics in furnace were studied by numerical simulation with k ε two equation turbulence model and stochastic particle trajectory model. And majoring in the slag problem of heat transfer surface of study prototype, adopting the arrangement form of homocentric two tangential circles of primary air and secondary air (CFSI), these results were compared with that of initial case, to seek practical and effective solving method in engineering practice.更多还原
