To prevent coking issues during biomass pellet combustion, 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 particles are prone to flying off and clogging.
Adequate Oxygen Supply: Sufficient oxygen supply is required for combustion to ensure complete reaction. Biomass boilers should ensure an ample oxygen supply 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 significant factor affecting combustion efficiency. Too low a combustion temperature can lead to incomplete combustion, while too high a temperature can easily cause carbonization. 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 properly controlled. Insufficient combustion time leads to incomplete burning, while excessive time can 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 deposits inside the combustion chamber, and cleaning the flue and heat exchanger, can prevent the occurrence of scaling issues.
Note that there may be differences between different types of biomass fuels and biomass boilers. Specific operations and adjustments should be made based on the actual situation. When making adjustments and

The brief steps for biomass boiler drying kiln are as follows:
Prepare Fuel: Select appropriate biomass fuel such as wood chips and straw, and perform pre-treatment like drying and sieving to ensure fuel quality and meet the furnace requirements.
Ignition and Ignition Adjustment: Place the fuel into the combustion chamber of the biomass boiler, ignite it, and adjust the ignition. Adjust parameters such as the oxygen supply, fuel supply, and combustion temperature in the combustion chamber to ensure stable combustion.
Heating and Temperature Control: As the fuel burns, biomass boilers produce high-temperature flue gases, which transfer their heat energy to the drying kiln through a heat exchanger. During the heating process, it is necessary to control the temperature of the drying kiln to ensure that the materials inside receive adequate heating.
Furnace Operation and Monitoring: During the furnace heating process, operation and monitoring are required. Operation involves controlling fuel supply, heat transfer, and the movement of materials inside the furnace. Monitoring includes parameters such as furnace temperature, pressure, and combustion efficiency to ensure normal operation and safety.
Furnace shutdown and cleaning: Upon completion of heating or achieving the required furnace effect, cease fuel supply and heating, and perform the furnace shutdown procedure. Post-shutdown, cleaning of the furnace and biomass boiler, combustion chamber, and flue is necessary.

Consider the following aspects when looking to purchase a high-performance and cost-effective hot water boiler:
Market Research: Before purchasing, conduct market research to understand various models of hot water boilers, comparing their performance, quality, and pricing differences. Information can be obtained through the internet, consultations with experts, or by referring to user reviews.
Choose Reliable: Opt for reputable hot water boilers, which typically offer high-quality product and after-sales service guarantees. You can assess their reputation by reviewing relevant materials, consulting experts, or referring to customer reviews.
Pay attention to product quality: When purchasing a hot water boiler, focus on the quality of the product. Check for certifications and compliance with standards, and understand the manufacturing process and material selection. Additionally, refer to customer reviews to learn about the actual usage of the product.
Performance and Requirement Alignment: Select a suitable hot water boiler model and specification based on your specific hot water needs and usage scenarios. Consider performance indicators such as the boiler's thermal efficiency, heating speed, and capacity to ensure they meet actual requirements.
Price Comparison: When selecting a hot water boiler, it's essential to compare prices, taking into account factors such as product performance, quality, and cost. Consult multiple suppliers for quotes and negotiate to secure a more reasonable price.
After-sales Service: When purchasing a hot water boiler, pay attention to the quality and guarantee of after-sales service. Understand the supplier's after-sales service policies, maintenance, and other details to ensure timely technical support and repair during use.

To prevent re-burning accidents at the tail end of biomass boilers, the following operational measures can be taken:
Optimize combustion parameters: Ensure the stability and completeness of the combustion process, avoiding fuel accumulation and secondary combustion in the tail section. Reasonably control parameters such as combustion temperature, air flow, and combustion time to maintain a smooth and thorough combustion process.
Enhance combustion chamber mixing and air flow distribution: By optimizing the combustion chamber structure and the design of the combustion system, ensure thorough mixing of fuel and air, avoiding fuel accumulation and secondary combustion at the rear. Rationalize the air flow distribution within the combustion chamber to ensure uniform fuel combustion.
Regular cleaning of furnace chamber and flue: Regularly clean the ash and carbon deposits within the furnace chamber to maintain its cleanliness. Clean the flue and waste heat recovery equipment to prevent the accumulation of particulates and ash in the flue gas, reducing the risk of re-burning.
Install Flue Gas Recirculation Unit: Install a flue gas recirculation unit 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 temperature to ensure the boiler operates normally.
Ensure thorough safety training and operational procedures: Conduct safety training for operators to enhance their understanding of biomass boiler operation and safety protocols.
