To prevent coking issues when burning biomass pellets, 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 millimeters. Larger particles can lead to incomplete combustion, while smaller particles are prone to scattering and clogging.
Adequate Oxygen Supply: Sufficient oxygen supply is required for combustion to ensure a complete combustion reaction. Biomass boilers should ensure an adequate oxygen supply in the combustion chamber, which can be achieved by adjusting the ventilation system and the operating parameters of the burner.
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 coking. 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 can lead to incomplete combustion, while too long a combustion time is prone to 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 in the combustion chamber, as well as the flue and heat exchanger, can prevent the occurrence of fouling issues.
Be mindful that biomass fuels and biomass boilers of different types may vary; specific operations and adjustments should be made based on the actual situation. When making adjustments and

The brief steps for the biomass boiler drying kiln are as follows:
Prepare fuel: Select appropriate biomass fuel, such as wood chips, straw, etc., and conduct pre-treatment, such as drying, sieving, etc., to ensure the quality of the fuel and its suitability for the furnace.
Ignition and Ignition Adjustment: Place the fuel into the combustion chamber of a biomass boiler, ignite it, and make ignition adjustments. 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 gas, which transfers its heat energy to the oven through a heat exchanger. During the heating process, it is necessary to control the oven's temperature to ensure that the material inside the oven receives adequate heating.
Furnace Operation and Monitoring: During the furnace heating process, both operation and monitoring are essential. 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: Once the furnace heating is complete or the desired effect is achieved, stop the fuel supply and heating, and perform the furnace shutdown operation. Afterward, the furnace and biomass boiler, combustion chamber, and flue need to be cleaned.

To purchase high-value hot water boilers, consider the following aspects:
Market Research: Before purchasing, conduct market research to understand the various models of hot water boilers, compare their performance, quality, and price differences. Information can be obtained through the internet, consultations with experts, or by referencing user reviews.
Choose Reliable: Opt for a reputable hot water boiler, which generally boasts high-quality products and after-sales service guarantees. Reputation can be assessed by reviewing relevant information, 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 Matching: 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 your actual requirements.
Price Comparison: When selecting a hot water boiler, it's essential to conduct a price comparison, taking into account factors such as product performance, quality, and price. Consult with multiple suppliers for quotes, compare and negotiate, to secure a more reasonable price.
After-sales Service: When purchasing a hot water boiler, pay attention to the quality and guarantees of the after-sales service. Understand the supplier's after-sales service policies, maintenance, and repairs to ensure timely technical support and maintenance during use.

To prevent rear combustion accidents in biomass boiler exhausts, the following operational measures can be taken:
Properly Adjust Combustion Parameters: Ensure the stability and completeness of the combustion process, avoiding fuel accumulation and re-burn in the tail area. Reasonably control combustion temperature, air flow, and duration to maintain a smooth and thorough combustion.
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, and avoid fuel accumulation and secondary combustion in the tail-end area. 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 soot buildup 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 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: Conduct regular operation monitoring and maintenance for 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, enhancing their understanding of biomass boiler operation and safety
