Possible reasons for incomplete combustion in biomass boilers may include the following aspects:
Poor fuel quality: Low-quality biomass fuel, such as fuel with high moisture content and uneven particle size, can affect the combustion process. Fuel with high moisture content can lead to a decrease in combustion temperature and incomplete combustion.
Insufficient air supply: Air is essential during the combustion process. If the air supply is insufficient, the fuel cannot react fully with oxygen, leading to incomplete combustion. Possible causes include a blocked air inlet or a faulty fan.
Unstable combustion system: The instability of the combustion system may also lead to incomplete combustion. For instance, 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 the combustion chamber: Ash buildup in the combustion chamber can affect the combustion process, obstructing fuel and oxygen contact, leading to incomplete combustion.
Insufficient burn time: Insufficient burn time can also lead to incomplete combustion. If fuel stays in the combustion chamber too briefly, it cannot burn completely, resulting in unburned fuel residue.
Improper combustion chamber design: An improperly designed combustion chamber, such as one that is too large or too small, hinders the thorough 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 the specific situation. Regular maintenance, reasonable fuel selection, and optimization of the combustion system, etc.

Biomass boilers can be categorized according to various classification criteria. Here are some common methods of classification:
By method of combustion classification:
Direct Combustion Boilers: Directly burn biomass fuel to generate heat energy.
Gasification Boiler: Converts biomass fuel into combustible gas, which is then burned.
Pyrolysis Boiler: Converts biomass fuel into combustible gases and solid carbon through pyrolysis, followed by combustion.
By fuel type:
Wood biomass boiler: Utilizes wood chips, wood shavings, cassava residue, and other wood-based fuels.
Crop Biomass Boiler: Utilizes crop waste such as straw, rice husks, wheat straw, etc., as fuel.
Industrial waste biomass boiler: Utilizes industrial waste materials such as sawdust and pulp sludge as fuel.
By boiler type:
Water-tube biomass boiler: Heat is transferred through water pipes arranged within the combustion chamber.
Fire-tube biomass boiler: Heat is transferred through fire tubes arranged within the combustion chamber.
Hybrid biomass boiler: Combines the features of both water-tube and fire-tube designs, incorporating both types of tubes.
By power scale classification:
Small biomass boiler: Power typically ranges from 1 to 10 MW, suitable for small buildings and rural heating.
Medium-sized biomass boiler: Power typically ranges from 10 to 50 MW, suitable for medium-sized industrial plants and large buildings.
Large biomass boiler: Power over 50MW, suitable for large industrial plants and centralized heating.
These categorization methods merely provide a general overview of biomass boilers; in reality, there are more detailed classifications and combinations. Different types of biomass boilers may vary in application scenarios and technical characteristics.

Developing biomass boiler heating is an effective measure to combat air pollution. Here are some relevant suggestions:
Replace high-pollution energy sources: Replace traditional coal boilers with biomass boilers to reduce emissions of air pollutants generated by coal combustion. The combustion of biomass fuel produces relatively fewer pollutants, resulting in less pollution to the atmosphere.
Enhance Combustion Efficiency: Improve the combustion efficiency of biomass boilers by optimizing the combustion process, reducing fuel waste and emissions of pollutants. Adjust combustion parameters such as combustion temperature and time to achieve a more complete burn.
Control Pollutant Emissions: Employed pollution control technologies such as flue gas desulfurization, flue gas denitrification, and particulate matter capture to reduce emissions. Install flue gas purification equipment to effectively remove pollutants like nitrogen oxides and particulates generated during the combustion process.
Enhanced Monitoring and Management: Establish a comprehensive monitoring system to monitor and evaluate the operation status and pollutant emissions of biomass boilers. Strengthen the management of biomass boilers to ensure regular maintenance and equipment care.

There are several methods for setting the pressure of biomass hot water boilers:
Regular Drainage: Regularly drain excess water from the boiler to maintain normal operating pressure. Draining excess water prevents overpressure inside the boiler, ensuring stable operation.
Operation: Perform operations at regular intervals based on the water level of the boiler to maintain normal working pressure. Be mindful of the control amount to avoid overfilling and causing excessive boiler pressure.
Pressure Control System: The pressure control system is installed to monitor the boiler's pressure in real-time via sensors and controllers, and automatically adjusts according to set values. When the boiler pressure exceeds the set value, the control system automatically reduces fuel supply or releases excess water to maintain a stable working pressure for the boiler.
Pressure Regulator: Install a pressure regulator on the boiler's water inlet pipe. By adjusting the valve opening, control the water inflow to maintain the boiler's stable working pressure. The pressure regulator can automatically adjust according to the set value, keeping the boiler's pressure within the appropriate range.
Pressure Regulator: Install a pressure regulator in the boiler's combustion system to control the steam pressure by adjusting the burner's combustion intensity. The pressure regulator can automatically adjust the burner's operating state according to the set value to maintain a stable working pressure of the boiler.
Above are common methods for setting the pressure of biomass hot water boilers. According to actual conditions and requirements, suitable pressure-setting methods can be chosen to maintain the stable working pressure of the boiler.
