  煤气灶里的空气太多是好是坏?煤气热风炉存在过量空气的问题是什么?煤气加热器空气过多的原因是什么?热风炉生产厂家向您解释说,煤气热风炉供气过剩
  Is it good or bad to have too much air in the gas stove? What is the problem of excessive air in the gas hot stove? What is the reason for excessive air in the gas heater? The producer of the hot stove explained to you that there is excess gas supply in the gas hot stove.
  燃气热风炉的剩余空气是指热风炉在加热燃烧过程中需要过量的空气,导致燃气燃烧不足。过剩空气系数是热风炉运行中实际空气消耗与理论空气需求之比。燃气的燃烧程度与燃烧设备和燃料类型有关。一般情况下,燃煤热风炉的过剩空气系数为1.3,油气热风炉的过剩空气系数为1.1,流化床热风炉的过剩空气系数为1.1~1.2。过剩空气系数的计算方法按GB/T 15317-94《工业热风炉节能监测方法》中公式1计算。
  The residual air of gas hot-blast stove refers to the excessive air required by the hot-blast stove in the process of heating combustion, resulting in insufficient combustion of gas. Excess air coefficient is the ratio of actual air consumption to theoretical air demand in hot blast stove operation. 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 blast stove is 1.3, that of oil-gas hot blast stove is 1.1, and that of fluidized bed hot blast stove is 1.1-1.2. The calculation method of excess air coefficient is calculated according to Formula 1 in GB/T 15317-94 "Energy-saving Monitoring Method for Industrial Hot Stove".
  那么如何控制煤气热风炉的余气现象呢?
  So how to control the residual gas of gas hot stove?
  通过燃烧调节佳空气含量,使热风炉热效率大化。热风炉作为一种热动力机械,在20世纪70年代末开始在我国广泛应用。它已成为电力热源和传统蒸汽动力热源的替代产品。通过长期的生产实践,人们认识到只有以热风为介质和载体才能大大提高热效率和热工效果。传统的电热源和蒸汽火电在输送过程中往往配备多个循环风机,从而间接形成热风进行干燥或加热。将省煤器出口的佳过剩空气系数控制在1.7以内,会增加机械不完全燃烧损失和化学非燃烧损失。

  By adjusting the optimum air content through combustion, the thermal efficiency of hot blast stove can be maximized. Hot blast stove, as a kind of thermal power machinery, began to be widely used in China in the late 1970s. It has become an alternative product of electric power heat source and traditional steam power heat source. Through long-term production practice, people realize that only using hot air as medium and carrier can greatly improve thermal efficiency and thermal effect. Traditional electric heat sources and steam thermal power are often equipped with multiple circulating fans in the transmission process, thus indirectly forming hot air for drying or heating. Controlling the optimum excess air coefficient of economizer outlet to less than 1.7 will increase the mechanical incomplete combustion loss and chemical non-combustion loss.
  根据供气情况的变化,调整风门的开度。如热风炉负荷减少,相应的燃料减少,燃烧所需的空气量也减少,此时要调整空气量,保持一定的过剩空气量。
  According to the change of air supply, adjust the opening of the air valve. If the load of hot blast stove decreases, the corresponding fuel decreases, and the amount of air required for combustion decreases, then the amount of air should be adjusted to maintain a certain amount of excess air.
  热风炉安装二氧化碳或氧气分析仪,自动检测烟气中的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。热风炉作为一种热动力机械,在20世纪70年代末开始在我国广泛应用。它已成为电力热源和传统蒸汽动力热源的替代产品。通过长期的生产实践,人们认识到只有以热风为介质和载体才能大大提高热效率和热工效果。传统的电热源和蒸汽火电在输送过程中往往配备多个循环风机,从而间接形成热风进行干燥或加热。
  Carbon dioxide or oxygen analyzer is installed in hot blast stove to automatically detect the content of carbon dioxide or oxygen in flue gas, analyze and adjust the air content in hot blast stove.
