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 instance, improper adjustment of the burner or不合理 design of the combustion chamber may 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.
Combustion chamber soot accumulation: Soot buildup in the combustion chamber can affect the combustion process, hindering fuel and oxygen contact, leading to incomplete combustion.
Burn time insufficient: Inadequate burn time can also lead to incomplete combustion. If the fuel remains in the combustion chamber for too short a time, 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, resulting in 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.

The YGL series organic heat carrier boiler is a boiler equipment that utilizes organic heat carriers to transfer heat energy. Its main components and characteristics are as follows:
Composition:
Furnace Body: The furnace body is the main component of the organic heat carrier furnace, including the furnace chamber, combustion chamber, and flue, etc. It is made of steel, offering excellent high-temperature resistance properties.
Combustion System: The combustion system includes burners, combustion fans, and combustion control systems, etc. The burners are responsible for injecting fuel into the furnace for combustion. The combustion fans supply the oxygen required for combustion. The combustion control system achieves automatic control of the combustion process.
Heat Exchange System: The heat exchange system includes heat carrier circulating pumps, heat carrier heaters, and heat carrier coolers, etc. The heat carrier circulating pump is responsible for circulating the heat carrier to the heater, where it is heated before being returned to the furnace, thus transferring heat energy. The heat carrier cooler is used to cool the heat carrier to ensure the stability of the heat carrier circulation.
Control System: The control system encompasses temperature controllers, pressure controllers, and safety protection devices, etc. The temperature controller is used for monitoring and regulating the furnace temperature, the pressure controller for monitoring and regulating the pressure of the heat carrier, and the safety protection device for ensuring the safe operation of the furnace and the heat exchange system.

High thermal efficiency: The YGL series organic heat carrier boiler uses organic heat carriers as the heat transfer medium, offering high heat transfer efficiency. Organic heat carriers can achieve liquid phase heat transfer at low temperatures, resulting in minimal heat loss and enabling more efficient fuel utilization.

The pressure maintenance methods for biomass hot water boilers mainly include the following:
Natural Circulation Pressure Maintenance: Natural circulation pressure maintenance refers to the process of circulating hot water to the heating system through natural convection within the boiler. Under the natural circulation pressure maintenance method, there is a significant difference in height between the supply and return water pipes of the boiler, achieving natural circulation through the density differences of the hot water. This method is suitable for small biomass hot water boilers, characterized by simplicity and economy.
Forced Circulation Constant Pressure: This method involves using a circulating pump to forcibly circulate hot water to the heating system. Under forced circulation constant pressure, the boiler provides sufficient water pressure through the circulating pump to ensure smooth flow of hot water. This method is suitable for large biomass hot water boilers and is characterized by stability.
Micro-positive Pressure Constant Pressure: Micro-positive pressure constant pressure maintains a slight positive pressure in the boiler system, ensuring stable circulation of hot water. Under the micro-positive pressure constant pressure method, the pressure in the boiler system is slightly higher than atmospheric pressure, driving the circulation of hot water through the pressure difference. This method is suitable for situations requiring higher heating temperatures and longer heating distances.
Above are the common methods of setting pressure for biomass hot water boilers. Depending on specific usage requirements and system design, the appropriate pressure setting method can be chosen to ensure the normal operation and heating effect of the hot water boiler.
