The biomass boiler combustion technology refers to the process of burning biomass fuel to release thermal energy. The following are common biomass boiler combustion technologies:
Burning Methods: Biomass boilers can utilize various burning methods, including direct combustion, gasification combustion, and liquefaction combustion. Direct combustion involves burning biomass fuel directly in the furnace; gasification combustion converts biomass fuel into combustible gases at high temperatures before burning; liquefaction combustion transforms biomass fuel into liquid fuel before burning.
Combustion Control: Biomass boilers require a combustion control system to regulate fuel supply, air supply, and the combustion process. By adjusting the ratio of fuel to air, control the combustion temperature and efficiency to achieve a stable combustion process.
Combustion Equipment: The combustion equipment of biomass boilers includes the furnace, grate, and combustion chamber, etc. The furnace is the main combustion area, the grate supports and burns the fuel, and the combustion chamber provides an appropriate environment for combustion.
Combustion Equipment: To enhance the combustion efficiency and environmental performance of biomass boilers, combustion equipment such as preheaters, dust collectors, and desulfurization devices are often installed. Preheaters are used to increase the combustion temperature and thermal efficiency of the fuel, dust collectors are for removing particulate matter from flue gas, and desulfurization devices are for removing sulfur compounds from the flue gas.
Combustion Control and Monitoring: Biomass boilers require the installation of combustion and monitoring equipment.

To prevent recirculation accidents at the tail end of biomass boilers, the following operational measures can be taken:
Reasonably adjust combustion parameters: Ensure the stability and completeness of the combustion process, and avoid fuel accumulation and re-burning in the tail region. Reasonably control combustion temperature, air flow, and combustion time, etc., to maintain a smooth and thorough combustion process.
Enhance mixing and air flow distribution within the furnace: By optimizing the furnace structure and combustion system design, ensure thorough mixing of fuel and air, and prevent fuel accumulation and re-burning in the tail-end area. Rationalize the air flow distribution within the furnace to ensure uniform combustion of fuel.
Regular cleaning of furnace and flue: Regularly clean the ash and soot accumulation within the furnace to maintain its cleanliness. Clean the flue and waste heat recovery equipment, preventing particle accumulation and ash in the flue gases, and 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.
Enhanced Operation 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 comprehensive safety training and operational procedures: Conduct safety training for operators to enhance their understanding of biomass boiler operation and safety.

Biomass boiler drying kiln refers to the process of using a biomass boiler for kiln heating. Here are the brief steps:
Prepare Fuel: Select appropriate biomass fuel, such as sawdust and straw, and carry out pre-treatment, such as drying and sieving, to ensure fuel quality and meet the requirements of the furnace.
Ignition and Ignition Adjustment: Place the fuel into the combustion chamber of the biomass boiler, ignite, and adjust the ignition. Ignition adjustment involves adjusting parameters such as the oxygen supply to the combustion chamber, fuel supply, and combustion temperature to ensure stable combustion.
Heating and Temperature Control: As fuel burns, biomass boilers produce high-temperature flue gas, which transfers its heat energy to the kiln through a heat exchanger. During the heating process, it is necessary to control the temperature of the kiln to ensure that the materials inside receive adequate heating.
Furnace operation and monitoring: During the furnace heating process, both operation and monitoring are required. Operation involves controlling fuel supply, heat transfer, and the movement of materials inside the furnace. Monitoring includes tracking parameters such as furnace temperature, pressure, and combustion efficiency to ensure normal operation and safety.
Furnace shutdown and cleaning: Upon completion of the heating process or achieving the required furnace effect, stop fuel supply and heating to initiate the furnace shutdown procedures. Post-shutdown, it is necessary to clean the furnace and biomass boiler, as well as the ash and soot in the combustion chamber and flue, to maintain the cleanliness and proper operation of the equipment.

slag formation in biomass boiler furnaces is caused by the ash and other impurities in biomass fuel that accumulate in the furnace during the combustion process. The following are some operational factors that affect slag formation in biomass boiler furnaces:
Fuel Characteristics: Different types of biomass fuels have varying ash content, ashing temperature, and ashing properties. Fuels with high ash content tend to produce a large amount of ash sludge, while those with lower ashing temperatures are prone to slagging inside the furnace.
Combustion Temperature: Combustion temperature is a significant factor affecting slagging in biomass boiler furnace. Excessively low combustion temperature can lead to incomplete fuel combustion and insufficient melting of ash, increasing the likelihood of slagging.
Air Supply: Excessive air supply can lower the combustion temperature, increase the residence time of fuel in the furnace, and raise the risk of slagging. Conversely, insufficient air supply can also lead to incomplete combustion of the fuel, increasing the generation of ash and slag.
Furnace Chamber Design: The design of the furnace chamber significantly impacts the airflow and temperature distribution within. A well-designed furnace chamber promotes complete fuel combustion and efficient slag discharge, reducing the likelihood of slagging.
Ash Cleaning System: The performance and operation of the ash cleaning system also affect the slagging condition in the furnace. Regularly cleaning the ash and accumulated dust inside the furnace maintains the furnace's ventilation.
