What are the Conditions to Ensure Good Incineration of Waste?

In order to reduce the proportion of low-melting-point substances in garbage and reduce the risk of coking, the pre-treatment of garbage should be strengthened. By means of sorting, crushing and mixing, the composition of garbage can be optimized and the calorific value and uniformity of garbage can be improved. At the same time, the garbage classification system should be promoted to reduce the content of plastics and other substances that are easy to coke from the source.

To solve the problem of too high or too low calorific value of garbage, we can adopt the measure of mixing garbage with different calorific values. By mixing garbage with different calorific values, the overall calorific value is more uniform and stable, thus avoiding the situation of too high furnace temperature or incomplete combustion. This can not only reduce the risk of coking, but also improve the operating efficiency and stability of the incinerator.

According to the actual situation of the garbage and the design parameters of the incinerator, set a reasonable furnace temperature range. At the same time, strengthen the construction of temperature monitoring and regulation systems to ensure that the furnace temperature can be stabilized within the set range. By controlling the furnace temperature, the generation and accumulation of sticky substances can be effectively reduced, thereby reducing the risk of coking.

According to the combustion characteristics of the garbage and the operating status of the furnace, the air volume of the boiler is reasonably adjusted. By increasing or decreasing the oxygen supply, it is ensured that the garbage can be fully burned in the furnace and the heat generated is effectively utilized. At the same time, the construction of oxygen monitoring and automatic adjustment systems is strengthened to achieve real-time monitoring and precise adjustment of oxygen, thereby avoiding coking problems caused by insufficient or excessive oxygen supply.

Coating the inner wall of the furnace with an anti-coking coating or using materials with anti-coking properties can effectively reduce the coking phenomenon. These coatings and materials can reduce the adhesion of sticky substances on the inner wall of the furnace, thereby reducing the formation of coke blocks. At the same time, regular cleaning and maintenance of the inner wall of the furnace is also an important task to prevent coking.

6. Introducing advanced technology and equipment

The introduction of advanced waste incineration technology and equipment can fundamentally improve the operation of the incinerator and reduce the risk of coking. For example, the use of high-efficiency low-nitrogen combustion technology and intelligent control systems can improve the incineration efficiency and reduce pollutant emissions; at the same time, new refractory materials and ash cleaning devices can effectively extend the service life of the furnace and reduce the occurrence of coking.

7. Establish a sound management system and emergency plan

A complete management system and emergency plan should be established to deal with possible coking problems, including regular inspection and maintenance plans, coking early warning mechanisms, and emergency response procedures, so as to promptly detect and deal with problems and ensure the stable operation and safe production of the incinerator.
