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 ones tend to scatter and clog easily.
Sufficient Oxygen Supply: Adequate oxygen supply is required for combustion to ensure a complete combustion reaction. Biomass boilers should ensure sufficient 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. Too low a combustion temperature leads to incomplete combustion, while too high a 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 also needs to be properly controlled. Insufficient combustion time can lead to incomplete burning, while excessive combustion time may 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, helps prevent coking issues.
Note that there may be differences between various types of biomass fuel and biomass boilers; specific operations and adjustments should be made according to the actual situation. When making adjustments and

The brief steps for biomass boiler drying oven are as follows:
Prepare fuel: Select appropriate biomass fuel such as wood chips and straw, and conduct necessary pretreatment like drying and crushing to enhance combustion efficiency.
Ignition: Place the fuel into the combustion chamber and ignite to start the combustion process. An igniter or other appropriate tool can be used for ignition.
Control the combustion process: Adjust the oxygen supply and fuel feed during combustion as needed to control the combustion temperature and heat output. This can be achieved by regulating the burner's switch, control panel, or automatic control system.
Oven Operation: Place the items to be baked into the oven according to specific oven requirements, ensuring even heating. Depending on the oven design and requirements, appropriate measures can be taken, such as adjusting the combustion chamber temperature and flue ventilation, to achieve the desired baking effect.
Monitoring and Adjustment: During the kiln process, it's necessary to monitor the combustion status, heat output, and kiln effect. Adjust the combustion parameters and operational methods promptly based on actual conditions to ensure stable kiln operation and achieve the required kiln effect.
Shut down and Clean: After the furnace operation is completed, stop the fuel supply and wait for the combustion chamber to cool down. Once the combustion chamber is fully cooled, proceed with the cleaning and maintenance of the furnace chamber, removing the ash and soot generated during the combustion process.
Above are the brief steps for the biomass boiler drying kiln. The specific operation process and precautions should be based on the boiler model, drying kiln requirements, and the manufacturer's instructions. During the operation,

Biomass boilers typically require auxiliary equipment to ensure their proper operation and utilization of biomass fuel. The following are some common auxiliary equipment:
Feeding System: Used to deliver biomass fuel to the combustion chamber of a boiler. The feeding system typically includes conveyors, screw conveyors, and vibratory feeders, among other equipment, which can be selected based on the fuel characteristics and boiler requirements.
Combustion System: Used for burning biomass fuel. The combustion system includes a combustion chamber, burners, fans, and other equipment, designed to achieve thorough mixing of fuel and air and control the combustion process.
Flue Gas Purification Equipment: Used for treating flue gases produced by combustion, reducing emissions of particulate matter and gas pollutants. Common flue gas purification equipment includes dust collectors, desulfurization devices, denitrification units, etc., which can be selected based on emission standards and environmental protection requirements.
Heat Exchangers: Devices used to transfer the thermal energy produced by combustion to water or other working fluids, achieving energy recovery and utilization. Heat exchangers typically include pipe-type heat exchangers, flue gas waste heat boilers, etc., which can enhance energy utilization efficiency.
Control System: Monitors and controls operational parameters of biomass boilers, including temperature, pressure, and fuel supply. The control system enables automatic adjustment and protection functions, ensuring safe and efficient boiler operation.
Equipment: Includes water supply systems, waste discharge systems, pressure vessels, fuel storage equipment, etc. These equipment are used to provide water for boilers, treat wastewater, store fuel, and ensure the normal operation of the boiler.
Here are some common auxiliary equipment for biomass boilers; the specific configuration and selection can be determined according to actual needs and project requirements.

A fully automatic biomass boiler refers to a biomass boiler equipped with a fully automatic control system. Here are some important points to consider:
Regular Maintenance: Although the fully automatic biomass boiler is equipped with an automatic control system, regular maintenance is still necessary. This includes cleaning the combustion chamber, heat exchanger, flue, and other components, checking and replacing worn parts, to ensure the normal operation of the boiler.
Water Treatment: The quality of water in biomass boilers is crucial for their normal operation. Regularly inspect and treat water quality, including water hardness, alkalinity, and impurities. Adopt appropriate water treatment measures based on water conditions to prevent scale and corrosion, and protect the boiler's heat exchangers and pipelines.
Fuel Quality Control: The quality of the fuel for biomass boilers is crucial for combustion efficiency and the stable operation of the boiler. Selecting the right quantity of biomass fuel and implementing proper quality control, including moisture content and particle size, ensures that the fuel meets the boiler's requirements and avoids incomplete combustion and blockages.
Regular cleaning of the combustion system: The combustion system of fully automatic biomass boilers requires regular cleaning, including the combustion chamber, burners, and burner nozzles. Accumulated soot, sediments, and dirt maintain the system's unobstructed flow, preventing incomplete combustion and unstable flames.
Regular System Inspections: The control system of fully automatic biomass boilers requires regular inspections and testing to ensure proper operation. This includes checking the accuracy of sensors and the stability of controllers. Promptly identify and resolve issues with the control system to ensure stable boiler operation.
Maintain Records and Monitor: Document operating parameters and fault conditions of all active biomass boilers, and conduct monitoring and analysis. Identify and address issues promptly to prevent faults from occurring or escalating.
Above are some precautions when using fully automatic biomass boilers. Through reasonable maintenance, quality control, and operation, the stable performance and work of the boiler can be ensured.
