Dust removal technology for coal-fired boilers is designed to reduce particulate emissions during the combustion process, protecting the environment and improving air quality. Here are several common dust removal techniques for coal-fired boilers:
Mechanical Dust Collectors: Mechanical dust collectors are a common type of dust removal equipment that separates particulate matter from flue gas through physical principles. Common mechanical dust collectors 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 particles to separate them from the flue gas.
Electrostatic Precipitator: An electrostatic precipitator uses 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-type Dust Collector: A wet-type dust collector wetts the particulate matter in flue gas with spray water or other liquids, then separates the wetted particles from the flue gas through gravity or inertial force. Suitable for treating flue gas with high humidity and sticky particles.
Electrostatic Precipitator: An electrostatic precipitator charges particles in flue gas using an electric field, and then collects the charged particles through the force of the electric field. Suitable for handling high-temperature flue gas and fine particles.
Dust and Desulfurization Integration Technology: The dust and desulfurization integration technology combines the two processes of dust removal and desulfurization into one, achieving integrated treatment by using shared equipment and jointly processing flue gas. This technology can reduce the footprint of equipment, lower investment and operational costs.
Above are common coal-fired boiler dust removal technologies, each suitable for different flue gas and particulate matter characteristics. In practical applications, an appropriate combination of dust removal technologies can be selected based on specific circumstances to achieve the goal of reducing particulate emissions.

The application methods for biomass boilers can be chosen and adjusted according to specific application needs and scenarios. Here are some common application methods:
Heating System: Biomass boilers can be used in heating systems to provide hot water or steam for buildings, industrial plants, 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 for industrial production.
Greenhouse Heating: Biomass boilers can be used in greenhouse heating systems to provide hot water or steam to greenhouses, maintaining the ideal temperature and humidity within the greenhouse, and promoting 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 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-based electricity production. By burning biomass fuel to produce steam, the steam drives the generator to generate electricity, achieving energy utilization and conversion.
Here are some common application methods for biomass boilers. According to specific needs and scenarios, suitable application methods can be chosen, and configurations and adjustments can be made in conjunction with relevant equipment and systems.

To prevent re-burning accidents at the tail end of biomass boilers, the following operational measures can be taken:
Rationally adjust combustion parameters: Ensure the stability and completeness of the combustion process, and prevent fuel accumulation and secondary combustion in the tail section. Reasonably control combustion temperature, air flow, and combustion time, etc., to maintain a smooth and thorough combustion process.
Enhance combustion chamber mixing and air flow distribution: By optimizing the combustion chamber structure and combustion system design, ensure thorough fuel and air mixing, and prevent fuel accumulation and re-burning in the tail section. Reasonably design the air flow distribution within the combustion chamber to ensure uniform fuel combustion.
Regular cleaning of the furnace and flue: Regularly clean the ash and carbon buildup inside the furnace to maintain cleanliness. Clean the flue and waste heat recovery equipment to prevent particle accumulation and ash in the flue gas, reducing the risk of reburning.
Install Flue Gas Recirculation System: Install a flue gas recirculation system at the boiler's tail to reignite the exhaust flue gas, enhancing combustion efficiency and reducing the likelihood of secondary combustion at the tail.
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 thorough safety training and operational procedures: Conduct safety training for operators, enhancing their understanding of biomass boiler operations and safety.

Biofuel boilers may encounter issues like ash accumulation and slagging during long-term operation. These problems can affect the boiler's combustion efficiency and safety. Here are methods to handle ash accumulation and slagging in biofuel boilers:
Regular Cleaning: Regularly cleaning the ash and carbon deposits inside the boiler is crucial for preventing the buildup of ash and slag. Cleaning schedules can be tailored based on the boiler's usage, including the combustion chamber, flue, and heat exchanger. During the cleaning process, appropriate tools and cleaning agents should be used 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 coking. For instance, adjusting the combustion temperature, oxygen supply, and combustion time to enhance combustion efficiency and minimize ash and slag formation.
Additives Usage: During biomass combustion, special additives such as ash inhibitor and slagging inhibitor can be added. These additives can reduce the formation of ash 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 inspecting and maintaining all components of biomass boilers, including burners, fans, flues, and heat exchangers, allows for timely detection and resolution of ash accumulation and scaling issues. During inspections, you can clear clogged parts and repair damaged ones to ensure the boiler operates smoothly.
Be mindful that dealing with biomass boiler ash and slagging issues requires a case-by-case approach. Consult with boiler maintenance personnel or manufacturers for more detailed and accurate advice. Additionally, regular cleaning and maintenance are crucial for preventing ash and slagging problems.
