After transformation of the technology of methanol loading waste incineration, it can make full use of heat produced by the waste gas combustion, improve the economic benefits of the methanol loading combustion device, and improve the system's environmental performance. At the same time, the furnace temperature is increased so that the exhaust gas is burned adequately in the fuenace with the burning machine flame, the heat generated by the exhaust gas after complete oxidation decomposition can reduce the fuel consumption, thereby lowering the production cost. Through repeatedly sampling emissions of the environmental protection department, the sampling success rate was 100%. The results show that the content of emission is far lower than the national standard specified value, and can achieve the requirement of the standard of air pollutants emission, and the fuel consumption is reduced by 94.5 t/a.
