摘　　要：燃气锅炉以天然气为燃料,燃烧产生热量生产饱和蒸汽或过热蒸汽。以某天然气净化厂CG-75/3.82-Q型燃气锅炉为例,分析了该锅炉生产运行中过量空气系数对锅炉热效率的影响,理论计算了不同炉膛烟气出口氧含量下的锅炉热效率及锅炉过量空气系数的合适区间,为燃气锅炉的配风操作提供了理论依据和技术支撑,可为同类研究提供思路。In this paper, a gas-fired boiler （CG-75/3.82-Q） gas-fired boiler is used as an example to analyze the effect of excess air supply on the boiler in the production and operation of the boiler.The boiler gas is used as a fuel to produce a saturated steam or superheated steam.The thermal efficiency of the boiler and the excess air coefficient of the boiler under different oxygen content of the furnace are calculated.The present study provides the theoretical basis and technical support for the gas distribution operation of the gas boiler, which can provide the idea for the similar research The.
