基于燃气互换性理论分析和压力式空/燃比例阀供气系统的功能研究发现,在工业炉进行焦炉煤气与天然气混空气转换应用时,当两种气质的华白数偏差为-2%～7%时,工业窑炉的热流量偏差也为-2%～7%,而燃气通过压力式空/燃比例阀进行供气燃烧后,工业窑炉过量空气缺少3%～11%,结合工程实际供气时空气系数一般为1.1～1.2时,气质转换后空气系数为1.07～1.17,满足正常的燃烧要求。实际试验结果也证明在系统不做巨大变更情况下,气质转换后工业窑炉能正常燃烧。
Based on the theory of gas interchangeability and the research on the function of the pressure air / fuel ratio control valve air supply system, it is found that when the coke oven gas is mixed with natural gas in the industrial furnace, when the deviation of the white numbers of the two temperaments is -2 % ~ 7%, the deviation of heat flow in industrial kilns is -2% ~ 7%. After the gas is supplied by the air / fuel proportional valve, the excess air in industrial kilns lacks 3% ~ 11% When combined with the actual air supply air coefficient is generally 1.1 to 1.2, the air quality after the conversion of the air coefficient of 1.07 to 1.17, to meet the normal combustion requirements. The actual test results also prove that in the system without great changes, the industrial furnace after the transition of temperament can be normal combustion.
