Description
At high temperatures, the combustible gases in the flue gas of a Domestic Waste Incinerator can burn fully. It can efficiently mix the gas generated by the gasifier with air for full combustion, preventing the escape of carbon substances in the flame and the occurrence of delayed combustion. When the flue gas enters the high – temperature combustion chamber, due to the use of tangential entry of the flue gas and tangential entry of the combustion – supporting air and other combustion – supporting methods, the flue gas can be fully burned again in the combustion chamber.
At the same time, the flue gas is dust – removed by the rotating airflow. The residence time of the incineration flue gas in the furnace is more than 2 seconds, so that the combustible gases in the flue gas and the combustibles in the fly ash are completely incinerated. A dry tail-gas purification device installed at the upper part of the Domestic Waste Incinerator adsorbs hydrogen chloride, sulfur oxides, and odor components, which are decomposed at high temperatures.
The flue gas purification system is equipped with calcium hydride filter bricks to carry out a neutralization reaction with acidic gases, achieving the purpose of adsorbing acidic gases and purifying the tail gas. This reduces the harmful components in the flue gas to below the specified values of national standards such as the “Pollution Control Standards for Hazardous Waste Incineration (GB18484 – 2001)”
