Blowing ash refers to the process of removing dust and deposits 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: During biomass combustion, a large amount of dust and soot is produced, which can adhere to the flue, furnace chamber, and heat exchange surfaces of the boiler, affecting the efficiency of heat transfer. Blowing dust can remove these accumulations, keeping the boiler clean.
Enhance Heat Transfer Efficiency: Ash and dirt accumulation on boiler flues, furnace walls, and heat exchange surfaces create thermal resistance, hindering heat transfer. Blowing off the dirt can eliminate this resistance, improve heat transfer efficiency, and reduce energy waste.
Prevent Scaling and Corrosion: Ash and dirt accumulation on the boiler flue and furnace can lead to excessively high local temperatures, causing scaling and corrosion issues. Blowing off the dust can reduce local temperatures and prevent the occurrence of scaling and corrosion.
Impact:
Boiler Heat Efficiency: Blowing dust can remove accumulated ash and dirt from the boiler flue, furnace, and heat exchange surfaces, enhancing the efficiency of heat transfer, thereby improving the boiler's overall heat efficiency.
Boiler Safety: Blowing ash can prevent slagging and corrosion in the boiler flue and furnace, reduce potential safety hazards, and ensure the safe operation of the boiler.
Boiler Stability: Blowing ash can maintain the cleanliness of the boiler, reduce the impact of accumulated ash and dirt on boiler operation, and enhance 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 required quantity to ensure that the moisture content and particle size meet the boiler's specifications. Low-quality fuel may lead to incomplete combustion and blockages.
Combustion Effect: Pay attention to monitoring and adjusting the combustion effect to ensure stability and completeness of the combustion process. Adjust combustion parameters, such as combustion temperature and duration, in accordance with the boiler's operating status and fuel characteristics.
Clean Combustion System: Regularly clean the combustion system, including the combustion chamber, burner, and burner nozzle. 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 of the boiler, including water hardness, alkalinity, and impurities. Take appropriate 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, lubricating, and tightening. Inspect all parts and connections of the boiler to ensure they are functioning properly and in good working condition.
Safe Operation: Adhere to the boiler operation procedures and safety regulations to ensure the safe operation of the boiler. Monitor and control parameters such as pressure and temperature, and handle abnormal situations promptly.
In summary, pay attention to fuel quality, combustion efficiency, cleanliness of the combustion system, water treatment, regular maintenance, and safety.

The pressure regulation methods for biomass hot water boilers mainly include the following:
Natural Circulation Pressure Regulation: Natural circulation pressure regulation refers to the circulation of hot water to the heating system through natural convection within the boiler. Under the natural circulation pressure regulation method, there is a significant difference in elevation between the supply and return water pipes of the boiler, achieving natural circulation through the density difference of the hot water. This method is suitable for small-scale biomass hot water boilers, characterized by simplicity and economy.
Forced Circulation Constant Pressure: Forced circulation constant pressure is achieved by using a circulation pump to force hot water to circulate through the heating system. Under the forced circulation constant pressure method, the boiler provides sufficient water pressure through the circulation pump to ensure smooth flow of the hot water. This method is suitable for large biomass hot water boilers, featuring stability and reliability.
Micro-positive Pressure Constant Pressure: Micro-positive pressure constant pressure maintains a slight positive pressure in the boiler system, allowing for 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 setting pressure method can be chosen to ensure the normal operation and heating effect of the hot water boiler.
