Throwing garbage is an inevitable behavior in our daily life. Where does the garbage end up? The answer is, waste incinerator or landfill. Landfill waste contaminates soil, water and the atmosphere, and can cause explosions and fires, and space is shrinking. The
waste to energy incinerator, while achieving good ecological benefits, can also provide clean electricity for use. Therefore, waste to energy incinerator is regarded as an important means to achieve waste reduction, harmlessness and resource utilization.
As of April 2022, about 760 waste to energy incinerator projects have been put into operation in my country, and the incineration processing capacity has reached 850,000 tons per day. What is even more rare is that the emissions of these waste incineration power plants have been monitored online in real time, and the public can check them at any time on the website of the Pollution Source Monitoring Center of the Ministry of Ecology and Environment.
Analysis of Incineration Power Generation Technology
In order to achieve better waste incineration effect and energy recovery, the incineration temperature of
waste to energy incinerator is not less than 850 °C, the residence time is not less than 2s, the thermal ignition loss rate of the incineration slag is not higher than 5%; the incineration capacity is greater than or equal to 300t/d; the incinerator The chimney shall not be less than 60m, and the chimney of other incinerators shall not be less than 45m; the chimney shall be provided with sampling holes according to the specification requirements.
Holy shield manufactures a high temperature pyrolysis gasifier. The use condition of pyrolysis furnace incineration is to isolate the air, the organic matter in the garbage is fully decomposed, and the hot steam is purified by using NaOH lye. This method is more advanced than the other two methods (circulating fluidized bed technology, layer combustion furnace technology), the structure of the furnace is also very simple, the equipment cost is nearly 50% less than the cost of the grate furnace, and the disadvantage is the treatment of the pyrolysis furnace. The capacity is relatively small (less than 150t/unit˙d), but we can also customize according to the processing capacity and garbage type.
