To improve the operating life of waste incinerators, the following measures can be taken:
Choose the right refractory material: Refractory materials used in waste incinerators need to have high-temperature resistance, corrosion resistance, and impact resistance. Choose high-quality refractory materials, such as high-alumina bricks, acid-resistant ceramics, etc., to ensure their stability and durability under high temperatures and corrosive environments.
Optimizing the combustion process: A reasonable combustion process can reduce corrosion and thermal stress in the waste incinerator, thereby prolonging the service life of the furnace body. Reduce damage to refractories by optimizing combustion parameters, controlling combustion temperature and gas distribution, etc.
Furnace protection measures: Use refractory materials such as ceramic bricks and refractory castables to protect the furnace wall in the garbage incinerator. In addition, metal covering or coating can be used to increase the anti-corrosion layer on the surface of the furnace body and improve the corrosion resistance of refractory materials.
Regular maintenance and overhaul: Regular maintenance and overhaul of waste incinerators, including furnace body cleaning, refractory repair, replacement, etc. Timely deal with problems such as ash accumulation and slagging in the furnace to prevent erosion and damage to refractory materials.
Control the chemical reaction in the furnace: For the acidic substances produced in the waste incinerator, the corrosion effect on the furnace body can be reduced by adding alkaline substances or controlling the composition of the waste. At the same time, pay attention to controlling the oxygen supply during the combustion process to avoid overheating and corrosion caused by excess oxygen.
Regular monitoring and testing: Through regular monitoring of furnace body temperature, pressure, gas composition, and other parameters, abnormal situations are found in time and corresponding measures are taken. Regular inspection and evaluation of refractory materials, timely repair or replacement of damaged parts.
To sum up, improving the operating life of waste incinerators requires a comprehensive consideration of the selection of refractory materials, the optimization of the combustion process, the strengthening of protection measures in the furnace, and regular maintenance and repair work.
