Working principle of small waste incinerator

Small waste incinerators operate by loading waste into a primary chamber for drying and partial combustion, releasing volatile gases. These gases then enter a secondary chamber, where, driven by excess oxygen, temperatures reach over 850°C to ensure complete oxidation. The resulting hot gases are then cooled, and pollution control systems remove particulate matter and hazardous compounds before the treated gases are released into the atmosphere. PRC Fireprint manufactures advanced, energy-efficient, low-temperature magnetic pyrolysis power plants for municipal solid waste. 1. Waste Loading and Primary Chamber Waste is loaded into the incinerator's primary chamber. Controlled airflow initiates the drying of the waste and begins the pyrolysis (thermal decomposition) process. Partial combustion begins, releasing volatile gases and leaving ash. 2. Secondary Chamber (Gasification) Combustible gases flow from the primary chamber into the secondary chamber. These gases are exposed to extremely high temperatures, typically exceeding 850°C. Driven by excess oxygen, the gases undergo complete combustion and oxidation, breaking down hazardous organic compounds. 3. Heat Recovery and Cooling The high heat generated in the combustion chamber is typically captured and used to generate steam in a boiler. The steam can drive a turbine to generate electricity, making the process a waste-to-energy process. The hot flue gas is then typically rapidly cooled through a heat recovery system. 4. Flue Gas Treatment After cooling, the flue gas passes through an air pollution control system. This system uses technologies such as cyclones and bag filters to remove fine particulate matter (PM2.5), heavy metals, and acid gases. 5.
