The waste incineration technology of heat storage incinerator can be divided into sanitary landfill, incineration, composting and recycling. The waste treatment technology has obvious effect in the traditional treatment of reducing the quantity of combustion. It is harmless and complete. It uses too much heat in a small area and reduces pollution. Considering the need to realize the sustainable development strategy in the more developed areas of China, Including combustion technology (i.e. incineration technology), flue gas purification technology, production process automation and control technology of municipal solid waste incineration technology, extensive use of technology, the remaining combustion furnace technology and flue gas purification technology. The technology of waste liquid combustion device has been developed for several years. At present, the waste incinerator and grate of fluidized bed incinerator and rotary incinerator account for more than 80% of the global waste incineration market.
 
 
 
The main advantages of regenerative incinerator are mature technology, stable operation, reliable, flexible, no pretreatment of solid waste can directly enter the furnace for combustion, especially for large-scale waste treatment, garbage incineration power generation can (or heat). However, the use of regenerative incinerator is also limited. High moisture content of sludge and large household garbage are not suitable for direct use of grate incinerator. The fluidized bed combustion device can be used for waste incineration. Generally speaking, the unburned material outside the furnace is the lowest in several aspects, which is conducive to environmental protection. However, due to the strict requirements on the pretreatment bed, the use of solid domestic combustion is very limited.
 
 
 
Although the existing fluidized bed incinerator is small, it is not widely used and should be further improved. The combustion technology of rotary furnace is a good development process. If there are a wide range of refractory materials or waste water processing waste in a large range of variants, the rotary furnace is the only ideal choice. Due to the change of rotation speed, the liquid waste incinerator will affect the retention time of slag. High temperature air and excessive oxygen will produce strong mechanical impact, which will lead to corruption and low concentration of combustible material slag cloth. Regenerative incinerator is a kind of device that uses the heat generated by combustion of auxiliary fuel to improve the temperature of combustible and harmful gas and reaction temperature, which leads to oxidative degradation.
 
 
 
The exhaust combustion system has "direct combustion" type and "regeneration type". "Direct combustion" only refers to combustion waste gas, heat recovery is not, but the exhaust combustion device used in the copper foil layer will be the most heat recovery, used for mechanical heating of rubber. In fact, the principle of "direct emission" and "regeneration" is the same, but the difference is that
 
 
 
Whether there is heat storage material in the furnace. The regenerative incinerator is suitable for flue gas treatment in spray drying equipment, and harmful gas emission in petrochemical and pharmaceutical industries. The regenerative incinerator is an oven, a refractory with high alumina content. The design of oxygen exhaust around the air hole can better contact with the atmosphere. The light diesel oil tank ignites automatically from the diesel combustion through the pipeline, opens the exhaust system, and the exhaust gas passes through the combustion nozzle, then oxidizes rapidly. According to the principle of 3 tons (temperature, time, current) combustion design, exhaust gas incinerator, combustion flame of main burner 2-3 M / s speed, and 2-3 M / s speed along the axial movement of the furnace body, greatly extending the residence time of the gas in the high temperature flame.
