Biomass boilers are prone to corrosion at high temperatures, primarily due to the following factors:
Fuel Composition: Biomass fuel contains certain ash and elements such as chlorine, which form corrosive substances like chlorides and salts under high temperatures during combustion. These substances react with the metal surface, leading to metal corrosion.
Combustion Conditions: Factors such as combustion temperature, oxygen content, and combustion rate during biomass combustion can affect corrosion. High temperatures, excessive oxygen, and rapid combustion rates can accelerate corrosion.
Smoke Composition: The smoke produced by biomass combustion contains certain acidic substances, such as, etc. These acidic substances will react with the metal surface, causing corrosion.
Flue Gas Condensation: During the flue gas condensation process of biomass boilers, water vapor in the flue gas condenses into liquid water, forming acidic condensate. This acidic condensate comes into contact with the metal surface, causing corrosion.
Metal Material Selection: The corrosion resistance of the metal materials used in biomass boilers also affects their performance. Different metal materials exhibit varying corrosion resistance to different corrosive media.
In summary, the causes of high-temperature corrosion in biomass boilers primarily include fuel composition, combustion conditions, flue gas composition, flue gas condensation, and the selection of metal materials. To mitigate corrosion issues,

The brief steps for biomass boiler drying oven are as follows:
Prepare fuel: Select suitable biomass fuel such as wood chips and straw, and conduct pre-treatment like drying and sieving 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 the biomass boiler, ignite, and adjust the ignition. Adjust parameters such as the oxygen supply to the combustion chamber, fuel supply, and combustion temperature to ensure stable combustion.
Heating and Temperature Control: As 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 materials inside receive adequate heating.
Furnace Operation and Monitoring: During the furnace heating process, both operation and monitoring are required. Operation involves controlling fuel supply, heat transfer, and the movement of materials within the furnace. Monitoring includes tracking parameters such as furnace temperature, pressure, and combustion efficiency to ensure normal operation and safety.
Furnace Completion and Cleaning: Upon completion of heating or achieving the required furnace effect, cease fuel supply and heating, and perform the furnace completion procedures. Post-completion, it is necessary to clean the furnace and biomass boiler, combustion chamber, and flue.

Biomass boilers may experience issues with ash accumulation and slagging during prolonged operation. These problems can affect the boiler's combustion efficiency and safety. Here are methods to address ash accumulation and slagging in biomass boilers:
Regular Cleaning: Regularly cleaning the ash and soot inside the boiler is crucial for preventing scaling and fouling. Cleaning schedules can be established based on the boiler's usage, including cleaning the combustion chamber, flue, and heat exchanger. During the cleaning process, appropriate tools and cleaning agents should be used to ensure the removal of ash and soot.
Adjust combustion parameters: Properly adjusting the combustion parameters of biomass boilers can reduce the occurrence of ash accumulation and slagging. For instance, adjusting combustion temperature, oxygen supply, and combustion duration, etc., can enhance combustion efficiency and decrease the generation of ash and slag.
Utilizing Additives: During biomass combustion, special additives such as ash inhibitor and slagging inhibitor can be added. These additives help reduce the formation of ash and carbon deposits, enhancing the boiler's cleanliness and combustion efficiency. The use of additives should be based on specific conditions and manufacturer recommendations.
Regular Inspections and Maintenance: Regularly inspect and maintain all components of the biomass boiler, including burners, fans, flues, and heat exchangers, to promptly identify and address issues like ash accumulation and coking. During inspections, you can clean clogged parts and repair damaged ones, ensuring the boiler operates smoothly.
Be mindful that dealing with biomass boiler ash and slagging issues requires a case-by-case approach. Consult with boiler maintenance personnel or manufacturers for more detailed and accurate advice. Additionally, regular cleaning and maintenance are crucial measures to prevent ash and slagging problems.
