Air Preheater for Waste Incinerator

The role and importance of waste incinerator air preheater

The air preheater plays a vital role in the waste incineration process.

Improved combustion efficiency: By preheating the air entering the incinerator, the waste can be burned more fully in the incinerator. This is because preheated air provides a higher initial heat and helps maintain the high temperature environment required for combustion reactions. For example, preheating the air to 200 - 300°C can significantly increase the rate and completeness of combustion of the waste and reduce the generation of incomplete combustion products.

Energy recovery and utilization: The waste incineration process generates a large amount of thermal energy, part of which is transferred to the incoming air through the air preheater, realizing effective recovery of thermal energy. This recovery reduces the waste incinerator's dependence on auxiliary fuels (e.g., natural gas, fuel oil, etc.), thereby reducing operating costs. At the same time, it is also in line with the concept of energy saving and emission reduction, and improves the energy utilization efficiency of the entire waste incineration system.

Reduced pollutant emissions: Full combustion helps reduce pollutant emissions. When waste is burned more completely, the generation of harmful pollutants such as carbon monoxide and dioxins is greatly reduced. For example, preheating air to raise the combustion temperature can effectively destroy the conditions for dioxin generation and reduce dioxin emissions, which is important for environmental protection.
