一种防止空气预热器阻力上涨的方法
摘要：
本发明涉及锅炉技术领域，具体公开了一种防止空气预热器阻力上涨的方法，该方法为：将送入空气预热器的空气加热至40‑80℃，然后送入空气预热器中，在空气预热器中加热后的空气与锅炉烟气发生热交换，之后锅炉烟气通过空气预热器烟气出口排出，此时排出的锅炉烟气的温度由之前的130℃提高至160‑200℃。通过提高空气预热器烟气出口的烟气温度，使硫酸盐水合物在此温度下分解，不会产生板结以及硬化，无法沉积在空气预热器上，进而有效避免了空气预热器的阻力上涨，延长了锅炉的运行周期。
摘要（英）：

The invention relates to the technical field of boilers, and particularly discloses a method for preventing resistance of an air preheater from rising. The method comprises the steps that air supplied to the air preheater is heated till the temperature ranges from 40 DEG C to 80 DEG C, and then the air is supplied to the air preheater; heat exchange happens to the air heated in the air preheater and boiler smoke; and then the boiler smoke is exhausted out from a smoke outlet of the air preheater, and the temperature of the boiler smoke exhausted at this moment is improved to 160 DEG C-200 DEG C from previous 130 DEG C. The smoke temperature of the smoke outlet of the air preheater is improved, and therefore sulfate aquo-complex is decomposed at the temperature, cannot be hardened and cannot deposit on the air preheater, then the resistance of the air preheater is effectively prevented from rising, and the operation cycle of a boiler is prolonged.
