就是利用锅炉尾部烟道中的烟气通过内部的散热片将进入锅炉前的空气预热到一定温度的受热面。用于提高锅炉的热交换性能，降低能量消耗。 一般简称为空预器。多用于燃煤锅炉。在锅炉中的应用一般为三分仓式。 使用时空预器缓慢旋转，烟气入口和空气入口不变。烟气进入空预器的烟气侧后排出，吸收了烟气热量的散热片在空预器的旋转下来到空气侧，将热量传递给空气。 附带系统主要有火灾报警（热点探测）、间隙调整、变频控制。
Air preheater
Is the use of flue gas boiler flue through the tail fin will enter inside the boiler air preheated to a certain temperature before heating surface. To improve the heat exchange performance of the boiler, reducing the energy consumption. Generally referred to as the air preheater. Used for coal-fired boilers. Applications in the boiler is generally trisector style. Using space-time pre-heater slowly rotating, gas inlet and an air inlet unchanged. Flue gas into the air pre-heater flue gas lateral discharged flue gas heat absorbing fins rotating air pre-heater down to the air side, the heat transfer to the air. With the main fire alarm system (hot spot detection), gap adjustment, frequency control.
