Coal-fired boiler dust removal technology is designed to reduce particulate emissions during the combustion process of coal-fired boilers, protecting the environment and improving air quality. The following are several common coal-fired boiler dust removal techniques:
Mechanical dust collectors: Mechanical dust collectors are one of the common dust removal equipment, separating particulates from flue gas through physical principles. Common types include gravity dust collectors, inertial dust collectors, bag dust collectors, etc. The working principle of mechanical dust collectors is to utilize the inertia, gravity, or filtering effect of particulates to separate them from the flue gas.
Electrostatic Precipitator: An electrostatic precipitator utilizes the force of an electric field to charge particles in flue gas, then collects the charged particles by the action of the electric field. There are two types of electrostatic precipitators: dry and wet. Dry electrostatic precipitators are suitable for high-temperature flue gas, while wet electrostatic precipitators are suitable for flue gas with high humidity.
Wet Dust Collector: A wet dust collector humidifies particulates in flue gas using spray water or other liquids, then separates the humidified particulates from the flue gas through gravity or inertial force. It is suitable for treating flue gas with high humidity and sticky particulates.
Electrostatic Precipitator: An electrostatic precipitator charges particles in flue gas using an electric field, and then collects the charged particles by the action of the electric field. It is suitable for the treatment of high-temperature flue gas and fine particles.
Dust and desulfurization integrated technology: This technology combines the dust removal and desulfurization processes into one, achieving integrated treatment by using shared equipment and jointly processing flue gas. It can reduce the footprint of equipment, lower investment and operational costs.
Above are common coal-fired boiler dust removal technologies. Different dust removal technologies are suitable for different flue gas and particulate matter characteristics. In practical applications, a suitable combination of dust removal technologies can be selected based on specific circumstances to achieve the goal of reducing particulate matter emissions.

The application methods for biomass boilers can be selected and adjusted according to specific application requirements and scenarios. Here are some common application methods:
Heating Systems: Biomass boilers can be used in heating systems to provide hot water or steam for buildings, industrial factories, etc. Heat energy can be transmitted through pipelines to the areas requiring heating, meeting the needs for heating and hot water.
Industrial Production: Biomass boilers can be used for thermal energy supply in industrial production processes, such as food processing, pulp and papermaking, and chemical industries. The thermal energy provided by biomass boilers meets the heating and steam requirements in industrial production.
Greenhouse Heating: Biomass boilers can be used in greenhouse heating systems to provide hot water or steam for greenhouses, maintaining suitable temperature and humidity within the greenhouse to promote plant growth.
Rural Heating: Biomass boilers can be used in rural heating systems to provide heating and hot water for rural residents. They can meet the heating needs of rural areas through either centralized or decentralized heating.
Hot Water Pump Drying: Biomass boilers can be used in hot water pump drying systems for drying wood, grain, and other materials. By providing hot water or steam, the drying process is accelerated, enhancing efficiency.
Biomass Power Generation: Biomass boilers can be integrated with power generation equipment for biomass power generation. By burning biomass fuel, steam is produced to drive the generator and generate electricity, achieving the utilization and conversion of energy.
Above are some common application methods for biomass boilers. According to specific needs and scenarios, the appropriate application method can be chosen, and configuration and adjustment can be made in conjunction with relevant equipment and systems.

To prevent the occurrence of tail combustion accidents in biomass boilers, the following operational measures can be taken:
Properly adjust combustion parameters: Ensure the stability and completeness of the combustion process, and avoid fuel accumulation and re-burning in the tail section. Reasonably control combustion temperature, air flow, and combustion time to maintain a smooth and thorough combustion process.
Enhance mixing and air flow distribution within the furnace: By optimizing furnace structure and combustion system design, ensure thorough mixing of fuel and air, and prevent fuel accumulation and re-burning at the tail end. Rationalize the air flow distribution within the furnace to ensure uniform combustion of fuel.
Regular ash and carbon removal from furnace: Regularly clean the ash and carbon buildup inside the furnace to maintain its cleanliness. Clean the flue and waste heat recovery equipment to prevent particle and ash accumulation in the flue gases, reducing the risk of re-burning.
Install Flue Gas Recirculation (FGR) Device: Install a flue gas recirculation device at the rear of the boiler to reignite the exhaust flue gas, enhancing combustion efficiency, and minimizing the possibility of rear-end re-burning.
Enhance operational monitoring and maintenance: Regularly monitor and maintain biomass boilers to promptly identify and address any anomalies. Monitor combustion parameters, flue gas emissions, and temperature, ensuring the boiler operates smoothly.
Ensure comprehensive safety training and operational procedures: Conduct safety training for operators, enhancing their understanding of biomass boiler operation and safety protocols.

Biomass boilers may experience issues like ash accumulation and slagging during prolonged operation. These problems can affect the boiler's combustion efficiency and safety. Here are methods to deal with ash accumulation and slagging in biomass boilers:
Regular Cleaning: Regularly cleaning the ash and carbon deposits inside the boiler is crucial for preventing scaling and fouling. A cleaning schedule can be established based on the boiler's usage, including cleaning the combustion chamber, flue, and heat exchanger, among other components. Appropriate tools and cleaning agents should be used during the cleaning process to ensure the removal of ash and carbon deposits.
Adjust combustion parameters: Properly adjusting the combustion parameters of biomass boilers can reduce the occurrence of ash accumulation and slagging. For instance, adjusting combustion temperature, oxygen supply, and combustion time can enhance combustion efficiency and decrease ash and slag formation.
Additives Usage: During biomass combustion, special additives such as slag inhibitor and ash agglomeration inhibitor can be added. These additives help reduce the formation of slag and carbon buildup, enhancing the boiler's cleanliness and combustion efficiency. The use of additives should be based on specific conditions and manufacturer recommendations.
Regular Inspections and Maintenance: Regularly inspect and maintain all components of the biomass boiler, including burners, fans, flues, and heat exchangers, to promptly identify and address issues like ash accumulation and slagging. During inspections, you can clear blocked parts and repair damaged components, ensuring the boiler operates smoothly.
Note that dealing with biomass boiler ash and slag buildup requires a case-by-case approach. Consult with boiler maintenance staff or manufacturers for more detailed and accurate advice. Additionally, regular cleaning and maintenance are crucial measures to prevent ash and slag issues.
