Incinerator

There are many classification methods from different perspectives.According to the classification of incineration chambers, it can be divided into: single-chamber incinerator and multi-chamber incinerator.According to the relationship between the combustion flue gas and the direction of the movement of garbage, the furnace body can be divided into downstream countercurrent AC and secondary flow.
Incinerators are a harmless treatment equipment commonly used in medical and domestic waste and animals for harmless treatment.The principle is to use coal, fuel, gas and other fuels to burn and carbonize the objects to be processed at high temperatures to achieve the purpose of disinfection.
There are many classification methods from different perspectives.According to the classification of incineration chamber, it can be divided into: according to the classification of furnace type, it can be divided into fixed grate furnace, mechanical grate furnace, and fluidized bed incineration furnace. ( Mainly used to deal with industrial waste )、 Rotary kilns, etc.To enhance the effect of domestic waste incineration, thermal decomposition and gasification are often used during incineration. ( Melt ) technology.The principle of grate incinerator is: supply garbage to heat-resistant cast iron ( steel ) ventilate from the lower part of the grate to burn the garbage.The incineration principle of a fluidized bed incinerator is: ventilate in the porous pipe at the bottom of the tower furnace, so that the sand layer on it flows into a flow layer. After the crushed garbage is put into it, it is connected to the flowing sand in the furnace. (650～ 800℃) Contact, thereby burning instantly, and the burned ash is brought to the flue gas treatment system by the combustion gas.The incineration principle of gasification melting furnace is: first put the garbage at 450 ～600℃ In the reducing atmosphere, the thermal decomposition is made into combustible gas and solid residue mainly composed of carbon, and then burned and melted.When designing an incinerator, the design should be comprehensively considered to the factory's treatment scale, the nature of the garbage to be treated, the grate mechanical load and heat load, the combustion chamber thermal load, the combustion chamber outlet temperature and flue gas retention time, and the thermal burn reduction rate.
