To prevent high-temperature corrosion issues in biomass boilers, the following measures can be taken:
Select appropriate materials: Choose corrosion-resistant metal materials for boiler components, such as stainless steel and heat-resistant steel. These materials offer excellent corrosion resistance and can maintain stability in high-temperature and corrosive environments.
Control combustion conditions: Reasonably control parameters such as the temperature, oxygen content, and combustion rate of biomass combustion to avoid excessive temperatures and oxygen levels, thereby reducing corrosion.
Pre-treatment fuel prior to combustion: Pre-treat biomass fuel, such as drying, screening, and decontamination, to reduce ash content and salt in the fuel, thereby lowering the risk of corrosion.
Regulate acidic substances in flue gas: By adding corrosion inhibitors or flue gas treatment devices, control the acidity level in flue gas, and reduce its corrosive effect on metal surfaces.
Regular cleaning and maintenance: Regularly clean the accumulated dust and dirt inside the boiler to keep it clean. During the cleaning process, use appropriate cleaning agents and tools to remove internal dirt from the boiler, preventing corrosion from occurring.
Regular Inspections and Maintenance: Regularly inspect and maintain biomass boilers to promptly identify and address corrosion issues. Assignable maintenance personnel can conduct regular inspections and maintenance work.

Biomass boilers offer the following environmental advantages:
Renewable Energy: The fuel used in biomass boilers is renewable energy, such as wood chips, straw, waste materials, etc. Compared to fossil fuels, the use of biomass fuel can reduce dependence on limited resources and lower energy consumption.
Low carbon emissions: The amount of carbon dioxide released during the combustion of biomass fuel is roughly equivalent to the amount absorbed during its growth, forming a closed carbon cycle. Compared to the combustion of fossil fuels, biomass boilers have lower carbon emissions, which have a cumulative effect in reducing greenhouse gas emissions.
Reduced Pollutant Emissions: The combustion of biomass fuel results in relatively lower emissions of pollutants. Compared to coal combustion, biomass boilers emit fewer nitrogen oxides, sulfur oxides, and particulate matter, causing less pollution to the atmosphere.
Waste Utilization: Biomass boilers can use waste materials as fuel, such as crop straw and wood scraps. If these wastes are not utilized, they may impact the environment. By utilizing biomass boilers, waste materials can be transformed into resources, reducing the issues of waste accumulation and disposal.
Heat Recovery Utilization: Biomass boiler flue gas contains a large amount of heat energy, which can be recovered and utilized through a flue gas waste heat recovery unit. Use the remaining heat in the flue gas for heating, hot water, and other applications to enhance energy efficiency and reduce energy waste.
Sustainable Development: High sustainability of biomass fuel

Blowing ash refers to the process of removing dust and deposits from the flue, furnace, and heat exchange surfaces of a boiler during its operation, by means of injecting high-pressure steam or compressed air. The function of blowing ash and its impact on the operation of biomass boilers are as follows:
Function:
Dust and soot: The combustion of biomass produces a significant amount of dust and soot, which adhere to the flue, furnace, and heat exchange surfaces of the boiler, affecting the efficiency of heat transfer. Blowing dust can remove these accumulations, keeping the boiler clean.
Increase Heat Transfer Efficiency: Ash and dirt accumulated on the flue, furnace chamber, and heat exchange surfaces create thermal resistance, hindering the transfer of heat energy. Blowing off the dust can eliminate this resistance, enhance heat transfer efficiency, and reduce energy waste.
Prevent Scale and Corrosion: Accumulated ash and dirt on the boiler flue and furnace wall can lead to excessively high local temperatures, causing scale and corrosion issues. Blowing ash can lower local temperatures and prevent the occurrence of scale and corrosion.
Impact:
Boiler thermal efficiency: Blowing dust can remove ash and dirt from the flue, furnace, and heat exchange surfaces, enhancing the efficiency of heat transfer, thereby improving the boiler's thermal efficiency.
Boiler Safety: Blowing ash can prevent scaling and corrosion in the boiler flue and furnace, reduce potential safety hazards, and ensure the safe operation of the boiler.
Boiler Stability: Blowing ash can maintain the boiler's cleanliness, reduce the impact of accumulated ash and dirt on boiler operation, and improve the boiler's efficiency.

Control methods for biomass boiler combustion systems can include the following aspects:
Fuel Supply Control: Regulate the quantity and speed of biomass fuel supply to ensure stable fuel availability. This can be achieved by controlling the feed conveyor's speed or adjusting the feed valve opening.
Air Supply Control: Regulate the air supply during the combustion process to ensure complete fuel combustion. Air supply can be controlled by adjusting the speed of the fan or the opening degree of the air door.
Combustion Temperature Control: Monitors and controls the furnace temperature during the combustion process, maintaining the combustion temperature within an appropriate range. The combustion temperature can be controlled by adjusting the air flow, fuel supply, and fuel distribution.
Combustion Process Monitoring: By installing temperature, pressure, and oxygen content sensors, among other monitoring equipment, we can continuously monitor parameters such as temperature, pressure, and oxygen levels during the combustion process, promptly identifying anomalies and making adjustments.
Flue Gas Emission Control: Monitor and control the release of pollutants in flue gas to ensure environmental friendliness in the combustion process. This can be achieved by installing flue gas analyzers and emission control devices, adjusting combustion parameters, and flue gas treatment equipment to reduce pollutant emissions.
Automated Control System: Utilizes an automated control system for comprehensive control and monitoring of the biomass boiler combustion system. Through PLC controllers, touchscreens, and other equipment, it achieves automatic adjustment of parameters and monitoring of operational status, enhancing the stability and efficiency of the combustion system.
In summary, through the rational supply of fuel, air, and control of combustion temperature, as well as monitoring and automated control of the combustion process, the stable operation of the biomass boiler combustion system can be achieved.
