摘　　要：针对我国生物质燃料燃尽困难的特性,为研究不同一次风风速下炉内空气动力场的变化规律,运用相似理论进行了燃生物质锅炉空气动力场冷态模化试验系统的研究。以SZS4-1.25-D型燃酒糟锅炉为原型,构建模化试验系统进行冷态等温模化试验研究,主要侧重于测试生物质能能否与空气混合。试验台的风量测试采用球型五孔探针和DT4020C型电子微压计进行测试。Based on the principle of similarity,the research of cold-state modeling experiment was carried out in the biomass-fired boiler.According to the experimental results,the distribution of the aerodynamic fields under the different first draft in furnace were presented,for optimizing the structure and improving the efficiency of the biomass-fired boiler.Taking SZS4-1.25-D boiler which was designed and manufactured by USST and Shanghai Sifang Boiler Group as prototype,the cold-state modeling experiment system was erected.According to the analysis of the experiment system,the main project of the table is to research if the air and fuel can be mixed or not.
