The effects of air preheating temperature on the burning characteristics of low calorific value gas was studied.
研究了不同空气预热温度对低热值煤气燃烧过程的影响。
The gas burning and air preheating procedure in flues operates on a cyclic basis in which some flues are burning gas and others are giving up their heat to incoming combustion air.
烟道中煤气的燃烧和空气的预热是循环进行的，当某些烟道正燃烧煤气时，另一些烟道则在加热导入的供燃烧用的空气。
The recuperators have high air resistance , low air preheating temperature and high fan pressure head , and fan has much noise to environment and are apt to break down with vibration .
此换热器空气阻力大，空气预热温度不高，风机压头高，环境噪声大，风机振动大、易损坏。
