如果忽视燃烧过程中的重要因素—烟囱的排烟温度,将成为生产过程中燃料损失的重要原因。要使燃料消耗量减少,就必须维持最低限度的过剩空气量。把热效率及燃烧管理提到最高限度,最重要的是在可行的情况下使排烟温度降到最低限度。一般说来,采用自然通风方式比强制感应通风操作更难避免排烟的热损 Ignoring the important factor in the combustion process, that is, the chimney’s flue gas temperature, will become an important cause of fuel loss in the production process. To reduce the fuel consumption, it is necessary to maintain the minimum amount of excess air. To maximize thermal efficiency and combustion management, it is of paramount importance that exhaust gas temperatures be kept to a minimum where practicable. In general, the use of natural ventilation is more difficult to avoid heat loss of smoke than forced induction ventilation
