Improvement in Super Heater Deposition of Straw Boiler Based on Numerical Simulation

摘要：

There is the problem of deposition exits generally in straw boiler super heater due to chlorine and alkalescent substance consists in the straw fuel,which agglomerate combustion material,especially for crops.Deposition does not only behave to raise the tube temperature,but also accelerate corrosion,even hide cartridge igniter trouble.This paper based on the study of some 75t/h plant to optimize the ash removal system of super heater.According to the CFD simulation,the flue flow situation in tube bundle of super heater diverse along with the position of the tube.Based on the regular of deposit researched from the simulation outcome,this paper propose to optimize the structure of shock wave soot blower of pattern BH-100 used by the plant,which did not performance a proper role.
