Possible reasons for incomplete combustion in biomass boilers may include the following aspects:
Poor fuel quality: Low-quality biomass fuel, such as excessive moisture content and uneven particle size, can affect the combustion process. Fuel with high moisture content can lead to reduced combustion temperature and incomplete combustion.
Insufficient air supply: Air is essential during the combustion process. If there is insufficient air supply, the fuel cannot react fully with oxygen, leading to incomplete combustion. Possible causes include blocked air intake, fan failure, etc.
Unstable combustion system: The instability of the combustion system may also lead to incomplete combustion. For example, improper adjustment of the burner, or an unreasonable design of the combustion chamber, can both affect the stability of the combustion process.
Insufficient combustion temperature: Low combustion temperature can lead to incomplete combustion. Possible causes include improper adjustment of the burner and unstable fuel supply.
Ash accumulation in combustion chamber: Ash buildup in the combustion chamber can affect the combustion process, obstructing the contact between fuel and oxygen, leading to incomplete combustion.
Insufficient combustion time: Inadequate combustion time can also lead to incomplete combustion. If the fuel stays in the combustion chamber for too short a time, it cannot burn fully, resulting in unburned fuel residues.
Improper Combustion Chamber Design: An improperly designed combustion chamber, such as one that is too large or too small, hinders the full mixing of fuel and oxygen, leading to incomplete combustion.
Above are some possible causes of incomplete combustion in biomass boilers, which require analysis and resolution based on specific circumstances. Regular maintenance, reasonable fuel selection, and optimization of the combustion system, etc.

Biomass boilers possess certain characteristics that give them an edge in energy conservation and environmental protection:
Renewable Energy: The fuel used in biomass boilers is renewable, such as wood chips, straw, waste, etc. Compared to fossil fuels, the use of biomass fuel can reduce dependence on limited resources and lower energy consumption.
Low carbon emissions: The amount of carbon dioxide released during the combustion of biomass fuel is roughly equivalent to the amount absorbed during its growth, creating a closed carbon cycle. Compared to the combustion of fossil fuels, biomass boilers have lower carbon emissions, contributing significantly to the reduction of greenhouse gas emissions.
Combustion: The biomass boiler utilizes advanced combustion and control technologies to ensure efficient combustion. By optimizing the combustion process, we enhance the utilization of thermal energy, reducing energy waste.
Waste Utilization: Biomass boilers can use waste materials as fuel, such as crop straw, wood waste, etc.

The DZL type quick-assembly biomass boiler is a common biomass boiler model with the following features:
Quick Installation: The DZL type quick-install biomass boiler features a modular design. The boiler body and equipment are pre-assembled in the factory, requiring only simple connections and adjustments on-site, significantly reducing installation time and project duration.
High combustion efficiency: Utilizes a special combustion chamber design and combustion system, ensuring complete combustion of biomass fuel within the furnace, resulting in high thermal efficiency. Additionally, equipped with an economizer and flue gas recirculation unit to further enhance thermal efficiency.
Automation Control: The DZL type quick-install biomass boiler is equipped with an automated control system, enabling the control and monitoring of the combustion process. With a PLC controller and a touch screen, parameters such as fuel supply, air supply, and combustion temperature can be adjusted to ensure the stable operation of the boiler.
Multiple Fuel Adaptability: The DZL type quick-assembly biomass boiler is suitable for various biomass fuels such as sawdust, straw, etc. Different fuels can be chosen according to actual conditions, enhancing fuel substitutability and flexibility.
Eco-friendly and Energy-saving: The DZL type rapid assembly biomass boiler uses biomass fuel, which results in relatively low emissions of flue gas and waste residues during the combustion process, and has a low content of pollutants in the emissions. The biomass fuel itself has the characteristics of low sulfur and low nitrogen, and the waste residues after combustion can be reused as organic fertilizer or biomass fuel, reducing environmental pollution.
Tightly Structured: DZL Type Quick Assembly Biomass Boiler

To prevent re-burning accidents at the tail end of biomass boilers, the following operational measures can be taken:
Rationalize combustion parameters: Ensure the stability and completeness of the combustion process, avoiding fuel accumulation and re-burning in the tail-end area. Reasonably control combustion temperature, air flow, and combustion time, maintaining a smooth and thorough combustion process.
Enhance combustion chamber mixing and air flow distribution: By optimizing the combustion chamber structure and combustion system design, ensure thorough fuel and air mixing, preventing fuel accumulation and secondary combustion at the tail end. Rationally design the air flow distribution within the combustion chamber to ensure uniform fuel combustion.
Regular cleaning of the furnace chamber and flue: Regularly clean the ash and carbon buildup inside the furnace chamber to maintain its cleanliness. Clean the flue and waste heat recovery equipment to prevent particle accumulation and ash in the flue gases, reducing the risk of re-burning.
Install Flue Gas Recirculation Device: Install a flue gas recirculation device at the rear of the boiler to reignite the exhaust flue gas, enhancing combustion efficiency, and reducing the likelihood of secondary combustion at the rear.
Enhance operational monitoring and maintenance: Regularly monitor and maintain biomass boilers to promptly identify and address any anomalies. Monitor combustion parameters, flue gas emissions, and temperatures to ensure the boiler operates normally.
Ensure safety training and operational procedures: Conduct safety training for operators to enhance their understanding of biomass boiler operation and safety protocols.
