Custom Waste Incineration Boiler

What are the common faults of waste incineration boilers? How to deal with these faults? Are there effective countermeasures?

1. Common faults of waste incineration boilers
Grate jamming and blockage: Due to the complex composition of garbage, it often contains large pieces of foreign matter or high-viscosity substances, which can easily lead to poor grate movement and affect combustion efficiency.
Ashing and coking on the heating surface: Fly ash and incompletely burned carbon particles generated during the combustion process are easy to deposit on the heating surface, reducing thermal efficiency, and causing overheating in severe cases.
Flue gas corrosion and wear: The flue gas generated by waste incineration contains corrosive gases (such as HCl, SOx) and particulate matter, which will cause corrosion and wear to boiler components under long-term action.
Unstable combustion: The calorific value of garbage fluctuates greatly, and the uneven feeding can easily lead to unstable combustion process, affecting boiler output and emission control.
Failure of the automatic control system: Complex control systems may have problems such as sensor failure and actuator failure during long-term operation, affecting the safe and stable operation of the boiler.
2. Troubleshooting methods
Grate jam and blockage treatment:
Preventive measures: The grate system designed by MHDB adopts advanced mechanical structure and intelligent control system, which can effectively identify and prevent large foreign objects from entering. It is also equipped with a strong vibration device to clean the grate regularly.
Emergency treatment: Once jamming occurs, immediately start the emergency procedure, use manual or mechanical methods to remove the blockage and restore the normal operation of the grate.
Heating surface ash and coking treatment:
Preventive measures: MHDB's waste incineration boiler adopts an efficient soot blowing system and an optimized flue structure to reduce ash accumulation and coking.
Cleaning measures: Regularly clean the heating surface online or shut down, using high-pressure water guns, air cannons or chemical cleaning methods.
Flue gas corrosion and wear protection:
Material selection: Use corrosion-resistant and wear-resistant high-performance materials, such as stainless steel, nickel-based alloys, etc.
Flue gas purification: The flue gas purification system provided by MHDB can effectively remove corrosive gases and particulate matter, reducing corrosion and wear on the boiler.
Unstable combustion treatment:
Optimize feeding: Use a precisely controlled feeding system to automatically adjust the feeding amount and air volume according to the change of garbage calorific value.
Combustion adjustment: Use MHDB's advanced combustion control system to monitor the combustion status in real time, adjust the combustion parameters, and ensure stable combustion.
Automated control system fault handling:
Daily maintenance: Regularly inspect and maintain the control system to ensure the accuracy and reliability of sensors and actuators.
Troubleshooting: Establish a rapid response mechanism. Once a fault occurs, immediately organize a professional team to troubleshoot and repair it.
3. Effective response measures
Technological innovation: MHDB continues to invest in research and development, introduces (super) supercritical Benson direct-current coal-fired boiler technology and low NOx NR combustion system technology, improves boiler efficiency and environmental performance, and fundamentally reduces the probability of failure.
Management system: Establish a complete design management, quality management, and project progress management system to ensure that every link from design to manufacturing, inspection, and testing meets the highest standards.
Training and service: Provide customers with professional operation training and after-sales service, improve the technical level and emergency handling capabilities of operators, and ensure long-term stable operation of boilers.
Intelligent monitoring: Utilize the Internet of Things and big data technologies to achieve remote monitoring and intelligent early warning of boiler operation, and discover and solve potential problems in advance.
