To prevent and mitigate corrosion issues in biomass boilers, the following methods can be adopted:
Regular Cleaning and Maintenance: Regularly clean the boiler's interior of accumulated dust and dirt to maintain its cleanliness. During the cleaning process, use appropriate cleaning agents and tools to remove interior dirt, preventing corrosion from occurring.
Regulate Water Quality: The water quality of biomass boilers significantly affects corrosion. Regular testing and adjustment of the chemical composition of the boiler water are necessary to control parameters such as the pH value, hardness, and oxygen content within suitable ranges. Water treatment equipment, such as water softeners and deaerators, can be used to improve water quality.
Prevent Oxygen Corrosion: Oxygen corrosion is one of the common forms of corrosion in biomass boilers. It can be mitigated by installing an oxygen scavenger in the boiler's feedwater pipes to remove oxygen from the water, thereby reducing the occurrence of oxygen corrosion. Additionally, chemical measures such as corrosion inhibitors can also be used to prevent oxygen corrosion.
Controlling the Combustion Process: High temperatures during combustion and acidic substances in the flue gas can also lead to corrosion. To control the combustion process, ensure that the combustion temperature and acidic substances in the flue gas are within the appropriate range. This can be achieved by adjusting the air flow for combustion, fuel supply, and fuel distribution.
Prevent Local Corrosion: Certain areas of boilers, such as the furnace and flue, are prone to corrosion. Reinforcement or coating protection with corrosion-resistant materials can be applied to these areas to extend their service life.
Regular inspections and maintenance: Regularly inspect and maintain biomass boilers to promptly identify and address corrosion issues. Entrust a maintenance crew for scheduled inspections and maintenance tasks.

To burn biomass pellets and avoid coking issues, 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 are prone to flying off and clogging.
Sufficient Oxygen Supply: Adequate oxygen supply is required for combustion to ensure complete reaction. Biomass boilers should ensure ample 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 crucial 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.
Proper combustion time: The combustion duration of biomass pellets must also be properly controlled. Insufficient combustion time leads to incomplete burning, while excessive duration can cause coking. Biomass boilers should adjust the combustion time based on 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 buildup inside the combustion chamber, as well as the flue and heat exchanger, can prevent the occurrence of coking 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 extinguishing process and maintenance methods for the fully automatic biomass boiler are as follows:
Extinguishing Process:
Discontinue Fuel Supply: Prior to extinguishing the biomass boiler, first discontinue the fuel supply to ensure the fuel supply pipeline is closed.
Turn off the burner: Switch the burner's switch or the extinguish button on the control panel to the off position to stop the burner from operating.
Wait for Cooling: Allow the boiler to cool to a safe temperature, which usually takes some time. Do not operate during this period to avoid accidents.
Shut off power: After the boiler has completely cooled down, turn off the power switch of the boiler to ensure the boiler is in a power-off state.
Maintenance Instructions:
Clean Combustion Chamber: Regularly clean the combustion chamber to remove ash and dirt generated during the combustion process. Use appropriate tools and cleaning agents to ensure the chamber remains clear and clean.
Heat Exchanger Cleaning: Regularly clean heat exchangers, especially those on the flue side. Combustion may produce particulates and slag in the flue gas, which can adhere to the surface of the heat exchanger, affecting heat transfer efficiency. Employing appropriate cleaning methods, such as mechanical or chemical cleaning, can help reduce the accumulation of dirt.
Inspect and Replace Critical Components: Regularly inspect and replace critical components such as burners, valves, sensors, etc. Ensure these components operate and perform normally to avoid malfunctions and safety hazards.
Water Treatment: Proper water treatment for boiler feedwater to prevent impurities and sediments from settling inside the boiler. Methods such as water softening, deoxygenation, and scaling removal can be employed to maintain the cleanliness and stability of the supply.
Regular Maintenance: Perform regular maintenance and upkeep, including inspecting and cleaning the control system, checking electrical connections, and lubricating moving parts. Develop a corresponding maintenance schedule based on the boiler's usage and the manufacturer's recommendations.
Above is the extinguishing process and maintenance methods for the fully automatic biomass boiler. Proper operation and regular maintenance ensure the safe operation of the boiler and extend its service life.

Slagging in biomass boiler furnace is caused by the accumulation of ash and other impurities generated during the combustion process of biomass fuel, which settle in the furnace. The following are some operating factors that influence slagging in biomass boiler furnaces:
Fuel Characteristics: Different types of biomass fuels have varying ash content, ashing temperature, and ashing properties. Fuels with high ash content tend to produce large amounts of ash slag, while fuels with lower ashing temperatures are prone to slagging inside the furnace.
Combustion Temperature: Combustion temperature is a significant factor affecting slagging in biomass boiler furnace. An excessively low combustion temperature can lead to incomplete fuel combustion and insufficient melting of ash, increasing the likelihood of slagging.
Air Supply: Excessive air supply can lower combustion temperature, increase the time fuel stays in the furnace, and raise the risk of slagging. At the same time, insufficient air supply can lead to incomplete fuel combustion, increasing the generation of ash and slag.
Furnace Design: The design of the furnace chamber significantly impacts the air flow distribution and temperature distribution within. A well-designed furnace chamber promotes complete combustion of fuel and the expulsion of ash, reducing the likelihood of slagging.
Dust Removal System: The performance and operation of the dust removal system also affect the slagging condition in the furnace. Regularly cleaning the ash and dust inside the furnace to maintain the furnace's ventilation
