To enhance the thermal efficiency of biomass boilers, the following measures can be taken:
Optimize the combustion system: Ensure the biomass boiler's combustion system operates effectively with high combustion efficiency. Adoptable combustion technologies, such as fluidized bed combustion and chain grate combustion, can enhance combustion efficiency and thermal energy utilization.
Control Fuel Quality: Select biomass fuels in controlled quantities, such as dry wood chips, straw, etc., and avoid fuels with excessive moisture content. High-moisture fuels consume additional heat for evaporation, reducing combustion efficiency.
Properly Adjust Fuel Supply: Adjust the fuel supply quantity according to actual needs to avoid excess or shortage. Excessive supply leads to fuel waste, while insufficient supply affects combustion efficiency.
Maintain optimal combustion temperature: Keep the combustion temperature within a suitable range, avoiding both excessively high and low temperatures. Excessively high temperatures can lead to heat loss in the fuel, while excessively low temperatures can affect combustion efficiency.
Regular cleaning and maintenance: Regularly clean the combustion chamber, flue, heat exchanger, and other components of the biomass boiler to keep them clean and unobstructed. Accumulated ash and dirt can affect heat conduction and heat exchange efficiency, reducing thermal efficiency.
Utilize waste heat recovery technology: Employ waste heat recovery units to utilize the excess heat generated from combustion for heating systems or other applications.

Biomass boilers offer several advantages:
Renewable Energy: Fuel for biomass boilers comes from organic materials such as plants, animals, and microorganisms, making it a renewable energy source. Compared to traditional fossil fuels, biomass fuel has lower carbon emissions and a smaller environmental impact, contributing to the reduction of greenhouse gas emissions and being more environmentally friendly.
Diverse Fuel Sources: Biomass fuel sources are abundant, including wood, straw, waste crops, food scraps, and municipal solid waste. This diversity in fuel sources allows biomass boilers to be flexible and adaptable, utilizing waste and by-products from plants and animals.
Environmental Friendliness: The carbon dioxide emitted during the combustion process of biomass boilers can be absorbed by plants, forming a cycle that reduces air pollution. Additionally, the emissions and ash produced by biomass boilers are relatively low, resulting in minimal environmental impact.
Energy Security: Biomass, as a local renewable energy source, can reduce dependence on imported energy, enhancing energy security. In regions with scarce resources, the use of biomass boilers can provide a reliable energy supply.
Economicity: Biomass fuel is relatively cost-effective, enabling a reduction in energy costs. Moreover, the technology and equipment for biomass boilers are continually evolving and maturing, making them more economically competitive.
Waste Utilization: Biomass boilers can utilize agricultural by-products such as crop straw, wood waste, etc., effectively utilizing waste resources and reducing resource waste.
In summary, biomass boilers offer advantages such as renewable energy, diverse fuel sources, environmental friendliness, energy security, economic efficiency, and waste utilization, making them a sustainable energy option.

Several factors need to be considered when selecting a suitable biomass boiler:
Fuel Type: First, determine the available biomass fuel types, such as wood chips, straw, etc. Different biomass fuels have varying characteristics, including moisture content, ash content, and calorific value, and it is necessary to choose a boiler suitable for the fuel type.
Boiler Capacity: Determine the required steam or hot water output based on actual needs and select an appropriate boiler capacity. Over-sizing leads to energy waste, while under-sizing fails to meet demand.
Combustion Efficiency: Focus on the boiler's combustion efficiency, which is the ratio of fuel converted to thermal energy. High combustion efficiency can enhance energy utilization and reduce operating costs.
Equipment Quality and Reliability: Choose biomass boilers and suppliers with excellent quality and reliability to ensure long-term stable operation and ease of maintenance.
Environmental Performance: Focus on the environmental performance of the boiler, including emission standards and reduction of pollutant emissions. The selected biomass boiler is beneficial for environmental protection and compliance with relevant regulations.
Economicity: Choose a cost-effective biomass boiler by considering the total cost of purchase, operation, and maintenance.
Adaptability and Flexibility: Select biomass boilers with high adaptability and flexibility based on actual needs and application scenarios, capable of accommodating various fuel types and operating conditions.
When selecting biomass boilers, consult boiler suppliers or engineers to conduct technical evaluations and economic analyses based on specific circumstances, and choose the appropriate type and specification of biomass boiler.

Controlling biomass boiler fouling is an essential measure to ensure the boiler operates smoothly and extend its lifespan. Here are some common methods for controlling biomass boiler fouling:
Select fuel wisely: Opt for high-quality, properly moisture-content biomass fuel, avoiding overly wet or excessively contaminated fuel to minimize the risk of slagging.
Regulate Combustion Temperature: Reasonably control the combustion temperature of biomass boilers to avoid excessively high temperatures, reducing the fuel's residence time in the furnace and lowering the risk of slagging.
Enhance furnace cleaning: Regularly clean the furnace to remove ash and accumulated dust, ensuring the furnace remains unobstructed and reducing the likelihood of coking.
Regulate Excessive Air: Properly control the air supply during the combustion process of biomass boilers to prevent excessive air from entering the furnace, thereby reducing the risk of fuel oxidation and slagging.
Regular Ash Blowing: Conduct regular ash blowing on components like economizers and superheaters of biomass boilers to remove ash and slag, maintaining the efficiency of heat exchange and reducing the likelihood of fouling.
Enhanced Monitoring and Inspection: Regularly monitor and inspect biomass boilers, including parameters such as furnace temperature, flue gas composition, and furnace pressure, to promptly identify anomalies and take appropriate actions.
These measures can help control the coking issue in biomass boilers, maintain the normal operation of the boiler, and extend the service life of the boiler. Additionally, based on specific circumstances, other appropriate measures can be taken in conjunction with actual operating experience and technical requirements.
