What is the working process of waste incinerator?

Garbage is manually put into the primary combustion chamber of the furnace body, and the primary combustion is started by automatic temperature control, and it is fully oxidized, pyrolyzed and burned in the combustion chamber of the furnace body according to the principle of three T's (temperature, time and eddy current). The flue gas generated by incineration enters the secondary combustion chamber, and the unburned harmful substances in the flue gas are further destroyed in the secondary combustion chamber. In order to thoroughly decompose unburned substances and meet the emission requirements, the secondary combustion chamber is equipped with a burner for combustion-supporting, and a unique secondary air supply device is configured to ensure that the flue gas can fully contact with oxygen at high temperature, and at the same time ensure the residence time of the flue gas in the secondary combustion chamber, and the air supply rate is adjusted according to the oxygen content of the flue gas at the outlet of the secondary combustion chamber. The temperature in the secondary combustion chamber is controlled, and the dust with large particles is removed by the dust collector, so that the incineration efficiency and the elimination rate can reach above 99%, thus achieving the effect of no odor, no odor and no smoke, and reaching the national emission standards. Then it enters the chimney and is discharged into the atmosphere, and the ash produced after combustion is taken out, screened, transported and buried manually.

Coal-water slurry of garbage incinerator is a mixture of water and pulverized coal, which can be transported, loaded and unloaded by pipeline pump like oil, stored in tanks, controlled by valves, atomized and burned by compressed air or pressure steam like heavy oil. Next, let's learn about the workflow of the garbage incinerator.

Workflow of waste incinerator:

1. The temperature of coal-water slurry burner of waste incinerator is 800~ 1000℃, and the coal-water slurry consumption is 800 ~1200 kg/h. ..

2. The combustion-supporting of the coal-water slurry burner keeps the garbage incinerator at a high temperature, helps the garbage to burn normally in the incinerator, makes the garbage burn through more easily, fully decomposes the harmful components therein, and improves the quality of garbage treatment.

3. Coal-water slurry combustion-supporting keeps the flue temperature of the secondary combustion chamber at1000 ~1100℃, and ensures that the reburning flue temperature is above 850℃.

4. At this time, dioxins are oxidized, completely burning hydrocarbons, destroying all toxic compounds and reducing the generation of acid gases.

5. Coal water slurry can make up for the shortage of heat value of garbage and ensure the normal combustion of garbage incinerator.

In the incineration technology of waste incinerator, oil has good combustion-supporting performance. In order to reduce the cost, improve the stability of equipment and ensure power generation, other combustion-supporting methods have been adopted, and coal water slurry is one of the current choices.
