To prevent the coking issue in biomass boilers, the following measures can be taken:
Choose the right fuel: Opt for biomass fuel with good quality and moderate humidity, avoiding overly wet or excessively contaminated fuel to reduce the risk of coking.
Control fuel supply rate: Regulate the rate of fuel supply to avoid too fast or too slow delivery, ensuring complete combustion of fuel and minimizing the risk of coking.
Maintain appropriate combustion temperature: Keep the combustion temperature at an appropriate level to avoid both too low and too high temperatures. Too low temperatures can lead to carbon deposition, while too high temperatures may cause incomplete combustion.
Control Air Supply: Properly regulate the air supply volume to ensure complete fuel combustion, avoid excessive air entering the combustion chamber, and reduce the risk of carbon coking.
Regular cleaning and maintenance: Regularly clean and remove ash and carbon deposits from the combustion chamber to maintain the boiler's cleanliness and prevent coking issues.
Install焦结监测设备: Install a焦结monitoringdevice to continuously monitor the coking situation inside the combustion chamber, and take timely measures for treatment to prevent further development of the coking issue.
Above are some common measures to prevent biomass boiler slagging, with specific preventive measures requiring adjustments and optimizations based on the boiler's specific conditions and operational requirements.

Biomass fuel refers to fuels made from biomass materials that can be used for energy production. Common types of biomass fuel include:
Timber and wood chips: Including firewood, charcoal, and wood pellets, etc.
Agricultural straw: such as corn straw, rice straw, etc.
Energy crops: such as sugarcane, corn, rapeseed, etc.
Animal Manure: Such as cow dung, chicken dung, etc.
Biogas produced from anaerobic fermentation of organic waste.
Bio-oil: such as vegetable oils, animal fats, etc.
Bioethanol: Ethanol fuel produced by fermentation of plants.
Biofuel: Fuel produced by esterification of vegetable oils or animal fats.
These biomass fuels are suitable for power generation, heating, and fuel substitution, featuring advantages such as being renewable and low in carbon emissions.

Biomass boilers can be categorized according to various classification criteria. Here are some common ways to classify them:
By type of combustion:
Direct Combustion Boiler: Directly burns biomass fuel to produce heat energy.
Gasification Boiler: Converts biomass fuel into combustible gas, which is then burned.
Pyrolysis Boiler: Converts biomass fuel through pyrolysis to produce combustible gas and solid carbon, which is then burned.
By fuel type:
Wood Biomass Boiler: Utilizes wood chips, wood shavings, cassava residue, and other wood-based fuels.
Crop biomass boiler: Utilizes crop residues such as straw, rice husk, wheat straw, etc., as fuel.
Industrial Waste Biomass Boilers: Utilize industrial waste such as sawdust and pulp sludge as fuel.
Categorized by boiler type:
Water tube biomass boiler: The combustion chamber is equipped with water tubes, which transfer heat through the tubes.
Fire-tube biomass boiler: Heat is transferred through fire tubes arranged within the combustion chamber.
Hybrid biomass boiler: Combines the features of water-tube and fire-tube designs, featuring both water tubes and fire tubes.
By power scale classification:
Small biomass boiler: Typically ranging from 1-10MW in power, suitable for small buildings and rural heating.
Medium-sized biomass boiler: Power typically ranges from 10 to 50 MW, suitable for medium-sized industrial plants and large buildings.
Large biomass boiler: Power over 50MW, suitable for large industrial plants and centralized heating.
These categorization methods merely provide a general overview of biomass boilers; in reality, there are more specific subcategories and combinations. Different types of biomass boilers may vary in application scenarios and technical characteristics.

Chain biomass boiler is a common type of biomass boiler, with its working principle and process as follows:
Fuel Supply: Biomass fuels (such as wood chips, straw, etc.) are transported to the combustion chamber of the chain boiler through the feeding system.
Combustion Process: The fuel is ignited in the combustion chamber while the chain boiler's chain system begins to operate. The fuel is gradually pushed forward by the chain movement, simultaneously burning within the combustion chamber. During combustion, the fuel is thoroughly mixed with air, and the heat energy produced is transferred to the boiler's water or other working medium.
Flue Gas Emission: The smoke produced by combustion is channeled through the flue system of the combustion chamber and released into the chimney. During the flue gas emission process, treatment with flue gas purification equipment can be employed to reduce the emitted particulate matter and gas pollutants.
Heat Recovery: The heat generated by combustion is transferred to water or other working substances through the heat exchanger of the boiler, raising their temperature. After heat recovery, the hot water or steam can be used for heating, hot water supply, or other industrial processes.
Control System: Chain biomass chain boilers are typically equipped with an automatic control system for monitoring and adjusting parameters such as temperature, pressure, and fuel supply during the combustion process. The control system can automatically adjust according to actual needs to ensure the safe operation and performance of the boiler.
Overall, the biomass chain grate boiler gradually feeds biomass fuel into the combustion chamber through a chain system for burning. The heat energy is transferred to water or other working substances via a heat exchanger, achieving heat recovery and utilization. This boiler boasts high combustion efficiency and strong fuel adaptability, and is widely used in heating, industrial heating, and other fields.
