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. The particle size should be controlled within an appropriate range, typically 3-5 millimeters. Larger particles can lead to incomplete combustion, while smaller particles 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 sufficient oxygen in 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 can lead to incomplete combustion, while a high temperature is prone to causing carbon buildup. 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. 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 soot inside the combustion chamber, as well as the flue and heat exchanger, can prevent the occurrence of coking issues.
Note that there may be differences between different types of biomass fuel and biomass boilers. Specific operations and adjustments should be made based on the actual situation. When making adjustments and

Biomass boilers, as equipment that converts thermal energy using biomass fuel, offer the following advantages:
Renewable Energy: Biomass fuel is a renewable energy source that can be continuously replenished through planting and cultivation. Its use has a smaller environmental impact compared to fossil fuels, promoting sustainable development.
Environmental Protection and Energy Saving: The biomass combustion process produces relatively little exhaust gas and waste residue, with low levels of pollutants emitted. Biomass fuel inherently features low sulfur and low nitrogen content, and the waste residue after combustion can be reused as organic fertilizer or biomass fuel, reducing environmental pollution.
Diversity and Flexibility: Biomass fuel types are abundant, including wood chips, straw, etc. Different fuels can be selected based on actual conditions, enhancing their substitutability and flexibility.
Utilization: The biomass boiler employs advanced combustion technology and heat conversion equipment, maximizing the thermal energy of biomass fuel for enhanced thermal efficiency. Additionally, equipped with an economizer and flue gas recirculation system, further thermal efficiency is achieved.
Economic Efficiency: Biomass fuel is more stable and cheaper compared to fossil fuels. The investment and operating costs of biomass boilers are relatively low, offering good economic efficiency.
Broad Application: Biomass boilers are suitable for various fields, including industrial production, heating, and power generation. They can meet the thermal energy demands in different scenarios.
In summary, biomass boilers offer advantages such as renewable energy, environmental protection, energy efficiency, diversity and flexibility, utilization, cost-effectiveness, and wide application, making them a sustainable thermal energy conversion solution.

The damage to the economizer tubes of biomass boilers may include the following situations:
Pipe Corrosion: Flue gas from biomass combustion contains certain acidic substances, which may lead to corrosion of the economizer pipes. Long-term corrosion can result in reduced wall thickness of the pipes, the formation of holes and cracks.
Pipe blockage: During biomass combustion, flue gas may contain some ash and particulate matter, which may settle and accumulate in the economizer pipes, leading to blockage. The blockage affects the flow of flue gas and reduces heat exchange efficiency.
Pipe fatigue: The varying operating temperatures and pressures in biomass boilers can lead to fatigue damage in economizer pipes due to long-term thermal expansion and contraction, such as cracks and deformation.
In response to the aforementioned issues, the following solutions can be implemented:
Enhanced Corrosion Protection Measures: Apply corrosion-resistant coatings internally on the economizer pipes or use corrosion-resistant materials for pipe construction to minimize corrosion occurrences.
Regular cleaning and maintenance: Regularly clean and maintain the economizer to prevent the accumulation of ash and particulates within the pipes, which can lead to blockages. Methods such as mechanical cleaning and water flushing can be employed.
Enhanced Monitoring and Inspection: Regularly inspect economizers, including thickness measurements of pipes and crack detection, to promptly identify issues and implement repair measures.
Optimize operational parameters: Reasonably adjust the operational parameters of the biomass boiler, such as combustion temperature and air volume, to minimize damage to the economizer.

The popularity of biomass thermal oil boilers can be attributed to the following reasons:
Environmental friendliness: Biomass thermal oil heaters use biomass fuels such as wood chips, straw, etc., which are renewable. The emissions produced during combustion are relatively low, causing minimal environmental impact. Compared to traditional coal thermal oil heaters, biomass thermal oil heaters can reduce the emission of harmful gases such as carbon dioxide, nitrogen oxides, and particulates.
Energy Sustainability: Biomass fuel is a renewable energy source with a relatively stable supply, but like fossil fuels, it is limited by geographical and resource constraints. The use of biomass thermal oil heaters helps reduce dependence on traditional energy sources and promotes the sustainable development of energy.
Low fuel costs: Biomass fuel is less expensive compared to traditional fuels like oil and gas. Utilizing biomass fuel can reduce energy costs and enhance energy efficiency.
Flexibility: The biomass thermal oil boiler is suitable for various biomass fuels such as sawdust, straw, etc., offering strong fuel adaptability. It allows for the selection of appropriate fuels based on actual conditions, enhancing flexibility and operability.
Gender: The biomass thermal oil furnace uses thermal oil as the heat transfer medium, featuring high heat transfer efficiency. The thermal oil boasts high thermal conductivity and stability, enabling effective heat energy transfer and utilization.
Widely Applicable: Biomass thermal oil heaters are extensively used in industrial sectors such as textiles, chemicals, and food processing. They provide a stable energy supply to meet the demands of industrial production.
