摘　　要：对全预混燃烧热风发生器进行燃烧实验,观察到该热风发生器的CO、NOx排放浓度都很低,通过对实验数据及误差进行分析,得出了CO、NOx的排放浓度和热风温度与热负荷和风量的关系,即CO、NOx的排放浓度随着风机风量的增大而减小,随着热负荷的增大而上升;一定风机风量下,热风温度随着热负荷的增大而增大,一定热负荷下,热风温度随着风机风量的增大而降低。Through the combustion tests of the pre-mixed Combustion Heat Blower, we can find the emission concentrations of CO and NOx are low, and by analyzing the experiment data the relations between emission concentrations, hot air temperature and heat load, air flow are obtained as well： Emission concentration of CO and NOx decreases as the air flow increases and increases as the heat load increases, and hot air temperature increases as heat load increases if air flow is constant and decreases with air flow increases if heat load is constant.
