The waste incineration power generation technology has obvious advantages of reduction, harmlessness and recycling in the field of household waste treatment, and in recent years, the waste incineration power generation technology has gradually replaced traditional waste treatment methods such as waste landfill and the like, is widely applied in China, and the number and the treatment capacity of waste incineration power generation facilities are increased year by year. Due to different living habits of residents in different areas, different influences on the living habits of the residents in different seasons and different living standards of the residents, the components of the household garbage are different, particularly the water content of the household garbage is more than 40-60%, and the typical value is 50%. In cold areas in the north, garbage can freeze, and in the process of collecting and transporting the garbage in winter, partial ice can be carried into a garbage incineration plant, so that the garbage incineration is difficult. In order to maintain the negative pressure in the garbage pool, the primary air of the incinerator is generally sucked in through the garbage pool. The air in the garbage pool is introduced from the outside, the outdoor temperature is low in winter, the temperature above the garbage pool is also low, and the primary air heating time of the preheater is long.
