When operating biomass boilers, the following safety precautions should be observed:
Familiarize with the Operation Manual: Before operating a biomass boiler, carefully read and familiarize yourself with the operation manual to understand the boiler's structure, working principle, operating steps, and safety precautions.
Regular inspections and maintenance: Conduct regular checks on all parts and equipment of the boiler to ensure proper operation and safety performance. Promptly clean ash and slag, inspect the sealing of pipes and valves, and maintain the boiler's cleanliness and unobstructed flow.
Regulate Fuel Supply: Control the rate and amount of fuel supply to avoid too fast or too slow delivery, ensuring complete combustion of fuel and reducing safety risks.
Maintain controlled combustion temperatures: Keep the combustion temperature at an appropriate level, avoiding both too low and too high temperatures. Too low temperatures can lead to carbon buildup, while too high temperatures may cause incomplete combustion and safety hazards.
Regular cleaning and maintenance of the combustion chamber: Regularly clean the ash and carbon deposits inside the combustion chamber to maintain the boiler's cleanliness and prevent coking and blockage issues.
Safety valves and pressure gauges: Ensure the proper operation and accuracy of safety valves and pressure gauges, and promptly repair or replace any damaged valves or gauges.
Prevent overheating and overpressure: Monitor the boiler's temperature and pressure to avoid overheating and overpressure situations, and take timely measures for adjustment and treatment.
Prevent Gas Leaks: Regularly inspect the sealing of gas pipes and valves to ensure no gas leaks occur, avoiding risks of fire and explosion.
Pre-shutdown procedures: Prior to shutdown, first turn off the fuel and air supplies, then wait for the boiler to cool down before performing maintenance and cleaning tasks.
Training and Operating Procedures: Ensure operators have received relevant training, are familiar with operating procedures and emergency response measures, and can handle emergencies correctly.
Above are some safety precautions to be aware of when operating biomass boilers. To ensure the safe operation of the boiler, it is recommended to follow relevant operational procedures and safety standards, and to conduct regular inspections and maintenance.

The damage to the economizer tubes of biomass boilers may include the following phenomena:
Pipe Corrosion: Flue gas produced by biomass combustion contains certain acidic substances, which may lead to corrosion of the economizer pipes. Long-term corrosion can result in the thinning of pipe wall thickness, the formation of holes and cracks.
Pipe blockage: During biomass combustion, flue gas may contain some ash and particulate matter, which may settle and accumulate in the economizer pipe, leading to blockage. Blockage can affect the flow of flue gas and reduce heat exchange efficiency.
Pipe fatigue: The varying operating temperatures and pressures in biomass boilers can lead to long-term thermal expansion and contraction, causing fatigue damage to economizer pipes, such as cracks and deformation.
For the aforementioned issues, the following solutions can be adopted:
Enhanced Corrosion Protection Measures: Corrosion treatment can be applied internally within the economizer pipes, such as by applying corrosion-resistant coatings or using corrosion-resistant materials to manufacture the pipes, to minimize corrosion occurrences.
Regular cleaning and maintenance: Regularly clean and maintain the economizer to prevent clogging by removing ash and particulates within the pipes. Methods such as mechanical cleaning and water flushing can be employed.
Enhanced Monitoring and Inspection: Regularly inspect economizers, including pipe thickness measurements and crack detection, to identify issues promptly and implement repair measures.
Optimize operational parameters: Reasonably adjust the operational parameters of the biomass boiler, such as combustion temperature and air volume, to minimize damage to the economizer.

The combustion process of biomass boilers typically includes the following steps:
Supply Fuel: Biomass fuel such as wood chips, straw, wheat straw, fruit shells, etc., is supplied to the combustion chamber. Fuel can be added to the combustion chamber automatically through the feeding system or manually.
Ignition: Ignite the fuel in the combustion chamber. Ignition can be achieved through an electric spark igniter, ignition fuel, or other ignition devices.
First Burn: Fuel begins to burn after ignition, initiating a combustion reaction. During the first burn stage, volatile components in the fuel start to release, producing combustible gases.
Vaporization and Combustion: The volatiles in the fuel vaporize at high temperatures, forming combustible gases such as methane and hydrogen. These gases mix with oxygen in the combustion chamber, initiating combustion reactions and releasing heat energy.
Combustion Control: By adjusting fuel supply, oxygen supply, and combustion chamber temperature, etc., the stability and efficiency of the combustion process are controlled. Automatic control systems can be used to regulate and optimize combustion.
Flue Gas Emission: During the combustion process, flue gas is discharged from the boiler through the chimney or flue gas exhaust system. The flue gas may contain pollutants such as soot, carbon dioxide, and nitrogen oxides, which require treatment through appropriate emission control equipment.
The combustion process of biomass boilers requires a reasonable fuel supply, oxygen supply, and combustion adjustment to achieve stable and environmentally friendly combustion effects. Different types of biomass boilers may have varying combustion methods and equipment, but generally follow similar combustion principles.
