Biomass boilers typically require auxiliary equipment to ensure their proper operation and utilization of biomass fuel. The following are some common auxiliary equipment:
Feeding System: Used to deliver biomass fuel to the combustion chamber of a boiler. The feeding system typically includes conveyer belts, screw conveyors, and vibratory feeders, among other equipment, which can be selected based on the fuel characteristics and boiler requirements.
Combustion System: Used for burning biomass fuel. The combustion system includes a combustion chamber, burners, fans, and other equipment, designed to ensure thorough mixing of fuel and air and to control the combustion process.
Smoke Purification Equipment: Used for treating flue gas produced by combustion, reducing emissions of particulate matter and gas pollutants. Common smoke purification equipment includes dust collectors, desulfurization units, denitrification units, etc., which can be selected according to emission standards and environmental protection requirements.
Heat Exchanger: Used to transfer the thermal energy generated by combustion to water or other working fluids, achieving heat recovery and utilization. Heat exchangers typically include water tube heat exchangers, flue gas waste heat boilers, etc., which can enhance energy utilization efficiency.
Control System: Monitors and controls operational parameters of biomass boilers, including temperature, pressure, and fuel supply. The control system enables automatic adjustment and protection functions, ensuring safe and efficient boiler operation.
Equipment: Includes water supply systems, sewage systems, pressure vessels, fuel storage equipment, etc. These devices are used to provide water sources for boilers, treat wastewater, store fuel, and ensure the normal operation of the boilers.
Above are some common auxiliary equipment for biomass boiler systems; the specific configuration and selection can be determined based on actual needs and project requirements.

To prevent accidents caused by secondary combustion in the tail end of biomass boilers, the following operational measures can be taken:
Properly Adjust Combustion Parameters: Ensure the stability and completeness of the combustion process, preventing fuel accumulation and recombustion in the tail-end area. Reasonably control combustion temperature, air flow, and duration 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 avoid fuel accumulation and re-burning in the tail-end area. Rationalize the air flow distribution within the furnace to ensure uniform combustion of the fuel.
Regularly clean the furnace chamber and flue: Regularly remove ash and carbon deposits from the furnace chamber to maintain cleanliness. Clean the flue and waste heat recovery equipment to prevent particle accumulation and ash in the flue gases, reducing the risk of re-burning.
Install Flue Gas Recirculation Unit: Install a flue gas recirculation unit at the rear of the boiler to reignite the exhaust flue gas, enhance combustion efficiency, and minimize the possibility 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 smoothly.
Ensure safety training and operational procedures: Conduct safety training for operators, enhancing their understanding of biomass boiler operations and safety.

The YGL series organic heat carrier boiler is a boiler equipment that utilizes organic heat carriers to transfer heat energy. Its main components and features are as follows:
Composition:
The Furnace Body: The furnace body is the main part of the organic heat carrier furnace, including the furnace chamber, combustion chamber, and flue, etc. Made of steel, it boasts excellent high-temperature resistance properties.
Combustion System: The combustion system includes burners, combustion fans, and combustion control systems. The burners are responsible for injecting fuel into the furnace for combustion, the combustion fans supply the oxygen required for combustion, and the combustion control system achieves automatic control of the combustion process.
Heat Exchange System: The heat exchange system includes a heat carrier circulating pump, a heat carrier heater, and a heat carrier cooler, etc. The heat carrier circulating pump is responsible for circulating the heat carrier to the heater, where it is heated before returning 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. The temperature controller is used for monitoring and adjusting the furnace temperature, the pressure controller for monitoring and adjusting the pressure of the heat carrier, and the safety protection device for ensuring the safe operation of the furnace and heat exchange system.
Features:
High thermal efficiency: The YGL series organic heat carrier boilers utilize organic heat carriers as the heat transfer medium, offering a high heat transfer efficiency. Organic heat carriers can achieve liquid-phase heat transfer at low temperatures, resulting in minimal heat loss and allowing for more efficient fuel utilization.

Biomass boiler furnace ash blowing refers to the cleaning operation of the combustion area within the furnace by means of an ash blowing device. The purpose of ash blowing is to remove ash and slag inside the furnace, maintain the unobstructed flow of the combustion area, and enhance both the combustion efficiency and the operational stability of the boiler.
Furnace ash blowing operations are generally divided into two methods: mechanical ash blowing and pulse ash blowing.
Mechanical Ash Blowing: Mechanical ash blowing is the process of cleaning the combustion area within the furnace chamber using mechanical devices, such as rotary ash blowers, chain-type ash blowers, and so on. The mechanical ash blower rotates or moves periodically to remove ash and slag from the combustion area.
Pulse Jet Cleaning: Pulse jet cleaning utilizes high-pressure gas or compressed air, which is then jetted into the combustion area of the furnace through nozzles, creating impact and vibration to remove ash and slag. It is characterized by its effective and rapid ash removal.
The impact of the furnace ash blowing operation on biomass boilers is mainly reflected in the following aspects:
Clean combustion area: The furnace blowing ash can burn the slag and ash in the combustion area, keeping the combustion area unobstructed, which is conducive to the complete combustion of fuel and improves combustion efficiency.
Reduce smoke resistance: Furnace ash blowing can burn the slag and accumulated ash in the combustion area, reducing the resistance in the smoke passage, which is conducive to the smooth exhaust of smoke, and improves the heat exchange efficiency of the boiler.
