摘要
Abstract
In porous media body applied to boiler equipment in order to study the combustion characteristic,based on the theory of porous media combustion,methane/Carbon dioxide premixed gas (1 ∶ 4) was established in 2.8 MW hot water boiler combustion of single step reaction model,through the numerical simulation,comparison and analysis of the porous medium body materials,location,and the influence of porosity on the combustion characteristic,it is concluded that the combustion temperature distribution,combustion emissions cloud distribution change.Results show that the porous medium material is silicon carbide,choose 0.5 and porosity of porous media is installed on 800 mm,is more advantageous to the boiler combustion.关键词
