Blowing ash refers to the process of removing dust and scale from the flue, furnace, and heat exchange surfaces of a boiler during its operation, by means of injecting high-pressure steam or compressed air. The function of blowing ash and its impact on the operation of biomass boilers are as follows:
Function:
Dust and soot: The combustion of biomass produces a large amount of dust and soot, which adhere to the flue, furnace, and heat exchange surfaces of the boiler, affecting the efficiency of heat transfer. Blowing ash can remove these deposits and keep the boiler clean.
Increase Heat Transfer Efficiency: Ash and dirt buildup on the flue, furnace, and heat exchange surfaces create thermal resistance, impeding the transfer of heat energy. Blowing off the soot can reduce this resistance, enhancing heat transfer efficiency and minimizing energy waste.

Impact:
Boiler thermal efficiency: Flushing can remove soot and dirt from the boiler flue, furnace, and heat exchange surfaces, enhancing the heat transfer efficiency, thereby increasing the boiler's thermal efficiency.
Boiler Safety: Blowing ash prevents scaling and corrosion in the boiler flue and furnace, reducing safety hazards and ensuring the safe operation of the boiler.
Boiler Stability: Blowing ash can maintain the boiler's cleanliness, reduce the impact of accumulated ash and dirt on the boiler's operation, and improve the boiler's efficiency.

During the operation of biomass hot water boilers, attention should be paid to the following aspects:
Fuel Quality: Select biomass fuel in the appropriate quantity to ensure the moisture content and particle size meet the boiler's requirements. Low-quality fuel can lead to incomplete combustion and blockages.
Combustion Effect: Pay attention to the monitoring and adjustment of the combustion effect to ensure the stability and completeness of the combustion process. Adjust combustion parameters such as combustion temperature and time according to the boiler's operating status and fuel characteristics.
Clean Combustion System: Regularly clean the combustion system, including the combustion chamber, burner, and burner nozzle, etc. Remove soot, deposits, and dirt to maintain the system's unobstructed flow and prevent issues such as incomplete combustion and unstable flames.
Water Treatment: Pay attention to the water treatment for the boiler, including water hardness, alkalinity, and impurities in the water. Adopt corresponding water treatment measures based on the water quality to prevent scale and corrosion, and protect the boiler's heat exchangers and pipes.
Regular Maintenance: Perform regular maintenance on biomass hot water boilers, including cleaning, lubrication, and tightening. Check all components and connections of the boiler to ensure they are functioning properly and in good working condition.
Safe Operation: Adhere to the boiler operation and safety procedures, ensuring the safe operation of the boiler. Monitor and control parameters such as pressure and temperature, and promptly address any abnormal situations.
In summary, pay attention to fuel quality, combustion efficiency, cleanliness of the combustion system, water treatment, regular maintenance, and safety.

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