Compared with landfill, incineration has unique advantages in reducing the amount and volume and recycling resources. Incineration of garbage is a relatively effective method to make garbage harmless, reduce the volume and recycle it. After high-temperature incineration, a large number of pathogens such as bacteria, viruses, parasite eggs in the garbage are completely eliminated; garbage incineration can also achieve energy recovery, which means converting the internal energy of garbage into heat energy and electrical energy, including incineration power generation, heating and cogeneration; Nowadays, a lot of garbage has packaging bags, and the food part in the packaging bags contains moisture.
