To prevent re-burning accidents at the tail end of biomass boilers, the following operational measures can be taken:
Properly Adjust Combustion Parameters: Ensure the stability and completeness of the combustion process, and avoid fuel accumulation and recombustion in the tail-end area. Reasonably control combustion temperature, air flow, and combustion time, maintaining a smooth and thorough combustion process.
Enhance combustion chamber mixing and air flow distribution: By optimizing the combustion chamber structure and combustion system design, ensure thorough mixing of fuel and air, preventing fuel accumulation and re-burning in the tail end. Reasonably design the air flow distribution within the combustion chamber to ensure uniform fuel combustion.
Regularly clean the furnace chamber and flue: Regularly remove ash and carbon deposits from the furnace chamber to maintain cleanliness. Clean the flue and waste heat recovery equipment to prevent particle accumulation and ash in the flue gases, reducing the risk of re-burning.
Install Flue Gas Recirculation Device: Install a flue gas recirculation device at the rear of the boiler to reignite the exhaust flue gas, enhancing combustion efficiency, and reducing the likelihood of secondary combustion at the rear.
Enhance operational monitoring and maintenance: Regularly monitor and maintain biomass boilers to promptly identify and address any anomalies. Monitor combustion parameters, flue gas emissions, and temperatures to ensure the boiler operates normally.
Ensure safety training and operational procedures: Conduct safety training for operators to enhance their understanding of biomass boiler operations and safety

To prevent coking issues when burning biomass pellets, the following measures can be taken:
Appropriate Particle Size: The size of biomass pellets is crucial for combustion efficiency. The particle size should be controlled within an appropriate range, typically 3-5 millimeters. Larger particles can lead to incomplete combustion, while smaller ones tend to disperse easily and cause blockages.
Sufficient Oxygen Supply: Adequate oxygen supply is required for combustion to ensure a complete reaction. Biomass boilers should ensure that there is ample oxygen within the combustion chamber, which can be achieved by adjusting the ventilation system and the operational parameters of the burner.
Appropriate combustion temperature: The combustion temperature of biomass pellets is also a critical factor affecting combustion efficiency. Too low a combustion temperature leads to incomplete combustion, while too high a temperature can cause coking. Biomass boilers should adjust the combustion temperature to an appropriate range based on the fuel characteristics and combustion requirements.
Proper combustion duration: The combustion time of biomass pellets should also be properly controlled. Too short a combustion time leads to incomplete combustion, while an extended combustion time can easily cause coking. Biomass boilers should adjust the combustion time according to the fuel characteristics and combustion requirements, ensuring it falls within an appropriate range.
Regular Cleaning and Maintenance: Biomass boilers require regular cleaning and maintenance to keep the combustion chamber and flue passages clear. Regularly cleaning the ash and carbon buildup in the combustion chamber, as well as the flue and heat exchanger, helps prevent the occurrence of coking issues.
Be mindful that there may be differences among various types of biomass fuels and biomass boilers. The specific operations and adjustments should be made based on the actual situation. When making adjustments and
