Combustion simulation and arch optimization of biomass chain boiler
Energy issues have always been one of the important factors affecting national development.In China,small chain boilers are widely used in factories that use biomass as fuel.In order to solve the problem that it is difficult to establish the solid phase model of chain boiler and to combine the results of gas-solid phased simulation in CFD software,the MATLAB was used as the data interface to connect FLIC solid phase simulation with FLUENT gas phase simulation,which can obtain relatively ideal numerical simulation results.Taking the boiler of a heat source plant in Shanxi as the research object,a numerical simulation analysis was conducted on the combus-tion of the boiler under different furnace arch structures.A boiler renovation plan was proposed to address the issue of high nitrogen ox-ide emissions from small chain boilers,in order to guide actual production.The results show that the renovation plan of delaying air dis-tribution and adding boiler arches can greatly reduce the emission of nitrogen oxides without affecting boiler efficiency,and the nitric ox-ide content at the flue gas outlet was reduced by about 49％.
