To prevent the coking issue in biomass boilers, the following measures can be taken:
Choose the right fuel: Select biomass fuel with good quality and moderate humidity, avoiding fuel that is too wet or contains excessive impurities, as this helps reduce the risk of coking.
Control fuel supply rate: Regulate the rate of fuel supply to avoid both too fast and too slow deliveries, ensuring complete combustion of the fuel and minimizing the likelihood 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 to ensure complete combustion of fuel, avoid excessive air entering the combustion chamber, and reduce the risk of 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 the occurrence of coking issues.
Install焦垢MonitoringEquipment: Install a fouling monitoring device to continuously monitor the fouling condition inside the combustion chamber, and take timely measures to address it, preventing further progression of fouling issues.
Above are some common measures to prevent biomass boiler slagging, with specific preventive measures requiring adjustment and optimization based on the specific conditions and operational requirements of the boiler.

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 logs, charcoal, and wood pellets, etc.
Agricultural straw: such as corn stalks, rice straw, etc.
Energy crops: such as sugarcane, corn, rapeseed, etc.
Animal Manure: Cattle dung, chicken dung, etc.
Anaerobic fermentation gas produced from organic waste.
Biomass oil: such as vegetable oils, animal fats, etc.
Bioethanol: Ethanol fuel produced by fermentation of plants.
Biofuel: Fuel produced through esterification of vegetable oils or animal fats.
These biomass fuels can be used for power generation, heating, and fuel substitution, offering benefits such as renewability and low carbon emissions.

Biomass boilers can be categorized according to different classification criteria. Here are some common methods of classification:
By combustion method classification:
Direct Combustion Boilers: Directly burn biomass fuel to generate heat energy.
Gasification Boiler: Converts biomass fuel into combustible gas before combustion.
Pyrolysis Boiler: Converts biomass fuel through pyrolysis to produce combustible gases and solid charcoal, which are 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 boiler: Utilizes 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 for heat transfer.
Fire-tube biomass boiler: Heat is transferred through the fire tubes arranged within the combustion chamber.
Hybrid biomass boiler: Combines the features of both water-tube and fire-tube designs, incorporating both water-tubes and fire-tubes.
By power scale classification:
Small biomass boiler: Power typically ranges from 1 to 10 MW, suitable for small buildings and rural heating.
Medium-sized biomass boiler: Power typically ranges from 10 to 50 MW, suitable for medium-sized industrial factories and large buildings.
Large biomass boilers: Power over 50MW, suitable for large industrial buildings and centralized heating.
These categorization methods merely provide a general overview of biomass boilers; in reality, there are more detailed and combined forms. Different types of biomass boilers may vary in application scenarios and technical characteristics.

Chain biomass boiler is a common type of biomass boiler, its working principle and process are as follows:
Fuel Supply: Biomass fuels (such as wood chips, straw, etc.) are delivered to the combustion chamber of the chain grate boiler through the feeding system.
The combustion process: Fuel is ignited in the combustion chamber while the chain boiler's chain system starts operating. 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 substance.
Flue Gas Emission: The flue gas produced by combustion is channeled through the flue system of the combustion chamber and discharged into the chimney. During the flue gas emission process, treatment can be carried out using flue gas purification equipment to reduce the particulate matter and gas pollutants emitted.
Heat Recovery: The heat produced by combustion is transferred to water or other working fluids through the boiler's heat exchanger, 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 and efficient operation 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.
