Possible reasons for incomplete combustion of fuel in biomass boilers may include the following aspects:
Inappropriate combustion conditions: In the combustion process, if the combustion temperature is too low, oxygen supply is insufficient, or the combustion time is inadequate, 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, among other reasons.
Fuel Quality Issues: The quality of fuel also affects combustion efficiency. If fuel contains excessive moisture, impurities, or ash, it can impact the calorific value and combustion properties during the combustion process, leading to incomplete combustion.
Impractical combustion chamber design: The design of the combustion chamber significantly affects the combustion efficiency. An unreasonably structured combustion chamber, insufficient combustion space, or uneven airflow distribution within the chamber can all lead to incomplete fuel combustion.
Combustion System Failure: A failure in the combustion system can also lead to incomplete fuel combustion. For instance, issues like a clogged nozzle in the burner, a malfunctioning 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. Accumulation of ash, slagging, or blockages inside the boiler 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 duration; select the right amount of fuel and ensure it is stored and handled properly; schedule regular maintenance and cleaning of the boiler to keep the combustion system running smoothly. 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 affect the occurrence of corrosion. High temperatures, excessive oxygen, and rapid combustion rates accelerate the corrosion process.
Smoke Composition: The smoke produced by biomass combustion contains certain acidic substances, such as... These acidic substances can react with the metal surface, 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 metal surfaces, causing corrosion.
Material Selection for Metal: 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 mediums.
In summary, the primary causes of high-temperature corrosion in biomass boilers include fuel composition, combustion conditions, flue gas composition, flue gas condensation, and material selection. 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 different characteristics from traditional fossil fuels, which tend to produce particulate matter like straw and wood shavings during combustion, leading to lower efficiency. Therefore, it is necessary to develop and improve combustion systems, optimize the combustion process, enhance efficiency, and reduce energy waste.
High-Temperature Corrosion Issue: Ash and elements like chlorine in biomass fuels are prone to cause corrosion at high temperatures, damaging the metal components of boilers. To address the high-temperature corrosion problem, it's necessary to develop and apply corrosion-resistant materials, control combustion conditions, and minimize corrosion.
Ash management and utilization: Biomass fuel combustion generates a large amount of ash, including waste, ash content, and unburnt materials. The management and disposal of ash is a significant issue, requiring the development and application of ash management technologies, including ash recycling, resource utilization, and chemical treatment.
By addressing these three issues, the combustion efficiency of biomass boilers can be further enhanced, corrosion risks reduced, and effective handling and utilization of ash and slag achieved, promoting the sustainable development of biomass energy.
