To prevent rear combustion accidents in biomass boiler tail sections, the following operational measures can be taken:
Properly Adjust Combustion Parameters: Ensure stability and completeness in the combustion process, and prevent fuel accumulation and secondary combustion in the tail section. Reasonably control combustion temperature, air flow, and combustion time to maintain a smooth and thorough combustion process.
Enhance mixing and air flow distribution within the furnace: By optimizing furnace structure and combustion system design, ensure thorough mixing of fuel and air, and prevent fuel accumulation and re-burning at the tail end. Rationalize the air flow distribution within the furnace to ensure uniform combustion of fuel.
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 (FGR) 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 tail end.
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 smoothly.
Ensure comprehensive safety training and operational procedures: Conduct safety training for operators to enhance their understanding of biomass boiler operations and safety protocols.

To burn biomass pellets and avoid coking issues, the following measures can be taken:
Appropriate particle size: The size of biomass particles is crucial for combustion efficiency. Particle size should be controlled within an appropriate range, typically 3-5 mm. Larger particles can lead to incomplete combustion, while smaller ones are prone to fly away and clog.
Sufficient Oxygen Supply: Adequate oxygen supply is required for combustion to ensure complete reaction. Biomass boilers should ensure ample oxygen supply within the combustion chamber, which can be achieved by adjusting the ventilation system and the operating parameters of the burners.
Appropriate Combustion Temperature: The combustion temperature of biomass pellets is also a significant factor affecting combustion efficiency. A low combustion temperature leads to incomplete combustion, while a high temperature can easily cause slagging. Biomass boilers should adjust the combustion temperature to an appropriate range based on the fuel characteristics and combustion requirements.
Appropriate Combustion Time: The combustion time of biomass pellets should also be appropriately controlled. Too short a combustion time leads to incomplete combustion, while too long a combustion time can easily cause coking. Biomass boilers should adjust the combustion time according to the fuel characteristics and combustion requirements, to 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 inside the combustion chamber, as well as the flue and heat exchanger, can prevent the occurrence of coking issues.
Note: Different types of biomass fuels and biomass boilers may vary; specific operations and adjustments should be made based on actual conditions. When making adjustments and
