Possible reasons for incomplete combustion of fuel in biomass boilers may include the following aspects:
Inappropriate combustion conditions: If the combustion temperature is too low, oxygen supply is insufficient, or combustion time is inadequate during the burning process, incomplete combustion of the fuel may occur. This could be due to improper burner settings, an unreasonable ventilation system, or inaccurate adjustment of combustion parameters.
Fuel Quality Issue: The quality of fuel can also affect combustion efficiency. If the fuel contains excessive moisture, impurities, or ash, it can impact the calorific value and combustion performance during the combustion process, leading to incomplete combustion.
Inadequate combustion chamber design: The design of the combustion chamber significantly impacts combustion efficiency. An improperly structured combustion chamber, insufficient combustion space, or uneven airflow distribution within the chamber can all lead to incomplete fuel combustion.
Burner System Failure: Faults in the burner system can also result in incomplete fuel combustion. For instance, issues like clogged burner nozzles, problems with the ignition system, or abnormal operation of the combustion fan can all affect the combustion efficiency.
Lack of maintenance and cleaning: Regular maintenance and cleaning of biomass boilers are crucial for maintaining combustion efficiency. If there is ash accumulation, slagging, or blockages inside the boiler, it can affect the normal combustion of fuel, leading to incomplete combustion.
To address incomplete fuel combustion, the following measures can be taken: adjust combustion parameters to ensure appropriate combustion temperature, oxygen supply, and combustion time; select the appropriate amount of fuel and ensure that storage and handling of the fuel meet requirements; perform regular maintenance and cleaning of the boiler to maintain the normal operation of the combustion system. Additionally, depending on the specific situation, it may be necessary to consult with boiler maintenance personnel or manufacturers for more detailed and accurate solutions.

Biomass boilers are prone to corrosion at high temperatures, primarily due to the following reasons:
Fuel Composition: Biomass fuel contains certain amounts of ash and elements such as chlorine, which, during combustion, form corrosive substances under high temperatures, such as chlorides and salts. 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 from biomass combustion contains certain acidic substances, such as sulfuric acid and nitric acid. These acidic substances can react with metal surfaces, causing corrosion.
Flue Gas Condensation: During the flue gas condensation process in 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.
Material Selection: The metal materials used in biomass boilers also affect their resistance to corrosion. Different metal materials exhibit varying corrosion resistance to different corrosive mediums.
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 alleviate corrosion issues,

In the technical aspect of biomass boilers, the following three issues need to be addressed with emphasis:
Enhanced Combustion Efficiency: Biomass fuel has characteristics different from traditional fossil fuels, which tend to produce particulates like straw and wood shavings during combustion, leading to lower efficiency. Therefore, research and improvement of combustion systems are necessary to optimize the combustion process, enhance efficiency, and reduce energy waste.
High-Temperature Corrosion Issues: Ash and elements like chlorine in biomass fuels can easily cause corrosion at high temperatures, damaging the metal components of boilers. To address high-temperature corrosion, it is necessary to develop and apply corrosion-resistant materials, control combustion conditions, and reduce the occurrence of corrosion.
Ash disposal and utilization: Biomass fuel combustion generates a large amount of ash, including waste, ash content, and unburned materials. The handling and disposal of ash is a significant issue, requiring the development and application of ash treatment technologies, including ash recycling, resource utilization, and chemical processing.
By addressing these three issues, we can further enhance the combustion efficiency of biomass boilers, reduce corrosion risks, achieve effective handling and utilization of ash and slag, and promote the sustainable development of biomass energy.
