1、 What is garbage incineration?

Incineration is mainly to decompose or destroy some organic substances under the action of oxygen and heat. During the combustion process, combustible substances are burned into ashes, domestic garbage is treated by high-temperature oxidation, and domestic garbage is burned at high temperature to convert combustible wastes into carbon dioxide and water, thus greatly reducing the amount of solid wastes and eliminating various pathogens.

Advantages of waste incineration:

1. Disinfect wastes;

2. Heat energy is generated through combustion, and the heat energy is recovered and utilized through pipes;

3. Eliminate some harmful organic wastes or organic wastes that can produce harmful substances after degradation;

4. It can also eliminate organic compounds that pollute inorganic products;

5. The weight and volume of waste landfill can be greatly reduced;

6. It can deal with pathological wastes produced by animals or people

2、 What are the main pollutants of waste incineration flue gas?

There are many kinds of pollutants in waste incinerator flue gas, such as particulate matter, nitrogen oxides, sulfur dioxide, mercury and its compounds, cadmium, hydrogen chloride, thallium and its compounds, dioxins, carbon monoxide, etc.

The composition of garbage is very complex. During the combustion process, the smoke and dust produced are toxic and complex harmful components, including some smoke and dust, trace metals and particles, and carcinogens such as dioxin and furan, which are extremely harmful to human body; Waste incineration of plastics or artificial cotton will also produce toxic gases such as chlorides, which will seriously pollute the air.

Among them, nitrogen oxides directly stimulate the lungs of the human body, making it difficult for people to resist respiratory system diseases such as colds. For people with respiratory system problems, they are more likely to be affected; For children, nitrogen oxides may cause impaired lung development in children.

We have rich experience in the treatment of exhaust NOx from diesel engines and gas engines. For fuels such as landfill gas and biogas produced by organic treatment plants, in addition to adding desulfurization devices, it is also necessary to consider the generation of siloxane by fuel mixture gas under high temperature conditions. Our team has developed a set of cost-effective and reasonable siloxane avoidance systems at the application end, Save the maintenance and operation cost of the power generation plant for the owner of the landfill gas power station. Our precise control, through many world-famous engine matching practices, high-precision sensors, exclusive designed electrical systems and the world's top electrical components, implements precise cooperation to ensure that the NOx and NH3 treatment efficiency in SCR and ASC systems meet the world's most stringent emission standards. The built-in cloud communication system provides real-time emission indicators for the pollution after treatment.
