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 flying off and clogging.
Adequate Oxygen Supply: Sufficient oxygen supply is required for combustion to ensure the complete reaction. Biomass boilers should ensure adequate oxygen supply 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 critical factor affecting the combustion effect. An overly low combustion temperature leads to incomplete combustion, while a too high combustion temperature is prone to 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 combustion time leads to incomplete combustion, while too long 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 inside the combustion chamber, and the flue and heat exchanger, can prevent the occurrence of fouling issues.
Note: Different types of biomass fuels and biomass boilers may vary; specific operations and adjustments should be made according to the actual situation. When making adjustments and

The biomass fuel boilers feature the following product characteristics:
Fuel diversity: Biomass boiler can accommodate various biomass fuels such as wood chips, straw, rice husks, etc. This diversity makes biomass fuel boilers more flexible and sustainable in energy utilization.
Environmental Low Emission: Biomass fuel boilers burn biomass fuel, resulting in relatively low emissions during combustion, such as particulates and nitrogen oxides. Consequently, biomass fuel boilers have lower carbon emissions and environmental pollution.
Energy-saving: Biomass fuel boilers utilize advanced combustion technology and heat recovery techniques to achieve efficient combustion and heat utilization. They offer high combustion efficiency and thermal efficiency, maximizing the energy extraction from biomass fuel.
Automated Control: The biomass fuel boiler is equipped with an automated control system that can accurately control and adjust parameters such as temperature, pressure, and fuel supply. The control system features safety protection functions to ensure the safe operation of the boiler.
High reliability and stability: The materials and processes used in biomass fuel boilers offer excellent durability and stability. Rigorous quality control and testing ensure the boiler's high reliability and long-term stable operation.
Flexible Application: Biomass fuel boilers are widely applicable in industrial, commercial, and residential sectors, including heating, central heating, and steam generators. They offer flexible installation methods and capacity options to meet diverse user requirements.

Preventing malfunctions is crucial for maintaining the smooth operation of biomass hot water boilers. Here are some methods for preventive maintenance:
Regular Inspections and Maintenance: Perform regular checks and maintenance on the biomass hot water boiler, including cleaning, lubricating, and securing. Verify that all parts and connections are functioning properly to ensure optimal operating condition.
Clean combustion system: Regularly clean the combustion system, including the combustion chamber, burners, and burner nozzles. Remove ash, sediment, and dirt to maintain the flow of the combustion system, avoiding incomplete combustion and unstable flames.
Check Water Quality: Regularly inspect the water quality of the biomass hot water boiler, including water hardness, alkalinity, and impurities in the water. Take appropriate water treatment measures based on the water quality to prevent scale and corrosion, and protect the boiler's heat exchangers and pipelines.
Cleaning Heat Exchangers: Regularly clean the heat exchangers of biomass hot water boilers to remove dirt and dust. Accumulated dirt and dust can reduce the heat transfer efficiency of the heat exchangers, affecting the boiler's thermal efficiency and operational stability.
Inspect safety valves and pressure gauges: Regularly inspect and test the safety valves and pressure gauges of the biomass hot water boiler to ensure proper operation. The proper functioning of the safety valves and pressure gauges is crucial for ensuring the safety and stability of the boiler.
Maintain records and monitoring: Document operational parameters and fault conditions of biomass hot water boilers, and conduct monitoring and analysis. Identify and resolve issues promptly to prevent faults from occurring or escalating.

Biomass boiler pellets are a common form of biomass fuel, also known as biomass pellets or wood pellets. They are small granular fuels produced by processing biomass raw materials (such as wood chips, straw, wheat straw, fruit shells, etc.) through processes like crushing, drying, and compression.
Biomass boiler pellet fuel boasts the following characteristics:
High Energy Density: Biomass pellet fuel has a high energy density, allowing for more energy to be stored in a relatively smaller volume, making it convenient for transportation and storage.
Easy to Burn: Biomass pellet fuel has regular shape and uniform size, ensuring a stable combustion process, easy control of combustion parameters, and improved combustion efficiency.
Low humidity and low ash content: The biomass pellet fuel has been dried and processed, resulting in low humidity and relatively low ash content. This reduces water evaporation and ash residue during combustion, improving combustion efficiency and reducing pollutant emissions.
Renewable and Eco-friendly: Biomass pellet fuel is a renewable energy source, capable of being recycled through regenerative processes. The carbon dioxide released during combustion can be absorbed by biomass regeneration, creating a cycle with minimal environmental impact.
Wide combustion adaptability: Biomass pellet fuel is suitable for biomass boilers and boasts strong combustion adaptability. Different types and specifications of pellet fuel can be chosen according to actual conditions to meet the needs of various boilers.
Biomass pellets are widely used in biomass boilers, representing a clean and renewable energy source that plays a significant role in reducing carbon emissions and protecting the environment.
