  燃气热风炉中的空气过多是好还是坏呢?燃气热风炉空气过剩会产生什么情况,出现什么问题呢?燃气热风炉空气过剩的原因是什么?热风炉厂家给你解释燃气热风炉空气过剩
  Is excessive air in gas hot stoves good or bad? What happens to excess air in gas hot stoves and what problems do they have? What are the causes of excess air in gas hot stoves? Hot stove manufacturers explain to you the excess air in gas hot stoves.
  燃气热风炉的空气过剩是指热风炉在燃烧供热时需要的空气过多,导致燃气不能充分燃烧。热风炉过量空气系数是热风炉运行中实际空气消耗量和理论空气需要量的比值。燃气的燃烧程度与燃烧设备、燃料种类有关。一般燃煤热风炉的过量空气系数为1.3,油气热风炉为1.1,流化床热风炉为1.1~1.2,过剩空气系数计算方法按GB/T 15317一94工业热风炉节能监测方法中公式1计算。
  The excess air of gas hot-blast stove refers to the excessive air needed by the hot-blast stove when burning for heating, which results in the insufficient combustion of gas. The excess air coefficient of hot blast stove is the ratio of actual air consumption and theoretical air demand in the operation of hot blast stove. The degree of combustion of gas is related to the type of combustion equipment and fuel. In general, the excess air coefficient of coal-fired hot stove is 1.3, the oil-gas hot stove is 1.1, and the fluidized bed hot stove is 1.1-1.2. The calculation method of excess air coefficient is based on Formula 1 of GB/T 15317-94 industrial hot stove energy-saving monitoring method.
  那如何控制燃气热风炉的空气过剩现象呢?
  How to control the excess air of gas hot stove?
  可以通过燃烧调整佳空气含量,使热风炉的热效率高。热风炉作为热动力机械,于20世纪70年代末在中国开始广泛应用,它在许多行业已成为电热源和传统蒸汽动力热源的换代产品。通过长时间的生产实践,人们已经认识到,只有利用热风作为介质和载体才能更大地提高热利用率和热工作效果。传统电热源和蒸汽热动力在输送过程中往往配置多台循环风机,使之终还是间接形成热风进行烘干或供暖操作。保持省煤器出口的佳过剩空气系数控制在1.7以内,造成机械不完全燃烧损失和化学不燃烧损失增大。
  The optimum air content can be adjusted by combustion, so that the thermal efficiency of hot blast stove is the highest. As a thermal power machine, hot blast stove began to be widely used in China in the late 1970s. It has become a replacement product of electric heat source and traditional steam power heat source in many industries. Through long-term production practice, it has been recognized that only using hot air as medium and carrier can the thermal efficiency and thermal work effect be improved greatly. Traditional electric heat source and steam heat power are often equipped with multiple circulating fans in the process of conveying, which eventually form hot air for drying or heating operation indirectly. Keeping the optimum excess air coefficient of economizer outlet within 1.7 will increase the mechanical incomplete combustion loss and chemical non-combustion loss.

  根据燃气供应的变化及时调整送、引风门开度。如热风炉负荷降低时,燃料相应减少,燃烧所需的空气量也相应减少,此时要调节风量,保持一定的过剩空气量。
  According to the change of gas supply, adjust the opening of the air inlet and outlet valve in time. If the load of hot stove decreases, the fuel and the amount of air needed for combustion will be reduced accordingly. At this time, the amount of air should be adjusted to maintain a certain amount of excess air.
  热风炉装二氧化碳或氧气分析仪,自动地检测烟气中二氧化碳或氧气含量,分析热风炉中的空气含量并进行调整。热风炉作为热动力机械,于20世纪70年代末在中国开始广泛应用,它在许多行业已成为电热源和传统蒸汽动力热源的换代产品。通过长时间的生产实践,人们已经认识到,只有利用热风作为介质和载体才能更大地提高热利用率和热工作效果。传统电热源和蒸汽热动力在输送过程中往往配置多台循环风机,使之终还是间接形成热风进行烘干或供暖操作。
  The hot blast stove is equipped with carbon dioxide or oxygen analyzer, which automatically detects the content of carbon dioxide or oxygen in the flue gas, analyses and adjusts the air content in the hot blast stove.
