Current biomass boilers face the following issues in practical application:
Fuel supply instability: The supply of biomass fuel is subject to seasonal and regional limitations, leading to unstable fuel supply for biomass boilers. This may result in the inability of biomass boilers to operate continuously or necessitate frequent fuel switching, which increases operating costs and management complexity.
Low combustion efficiency: Due to the characteristics of biomass fuel and the complexity of the combustion process, the combustion efficiency of biomass boilers is relatively low. Some fuels have high volatile content and ash content, which may produce excessive ash and particulate matter during combustion, thereby reducing combustion efficiency and heat utilization.
NOx Emission Issue: Biomass boilers produce a relatively high amount of nitrogen oxides (NOx) during the combustion process, which has a certain impact on the environment. Controlling and reducing NOx emissions is a significant challenge faced by biomass boilers.
Combustion Equipment Wear: The high ash content in biomass fuel leads to wear and clogging of the combustion equipment during the burning process. This may shorten the lifespan of the equipment, necessitating frequent maintenance and cleaning.
Ash residue from combustion: Ash residues produced by biomass boilers must be treated and disposed of properly. Improper handling may lead to environmental pollution and hazards.
Lack of unified technical standards and specifications: Currently, there is a lack of unified technical standards and specifications for biomass boilers.

During operation, biomass thermal oil heaters are prone to scaling due to the high temperature of the thermal oil and prolonged use. To prevent scaling, manufacturers of biomass thermal oil heaters typically adopt the following measures:
Select the appropriate thermal oil: Manufacturers choose thermal oils with good thermal stability and antioxidant properties to minimize the formation of scale. The selection of thermal oil should be reasonably matched according to the actual operating conditions and usage requirements.
Control oil temperature and flow rate: Manufacturers will rationally control the temperature and flow rate of the thermal oil based on its properties and operational requirements. Excessive temperature and rapid flow rates can easily lead to scale formation, so appropriate adjustments are necessary.
Regular Cleaning and Maintenance: Manufacturers recommend users to regularly clean and maintain biomass thermal oil heaters to remove scale buildup. Cleaning agents and equipment that can be used during the cleaning process, along with scale removal, will restore the normal operation of the heater.
Install filters and descaling devices: Manufacturers may install filters and descaling devices in biomass thermal oil heaters to filter out impurities and scale from the thermal oil. These devices can effectively prevent scale buildup and extend the service life of the thermal oil heater.
Regular Monitoring and Analysis: Manufacturers may advise users to regularly monitor and analyze the properties and quality of thermal oil, to detect anomalies promptly and take appropriate measures.

Chain biomass boiler is a common type of biomass boiler, with its working principle and process as follows:
Fuel Supply: Biomass fuel (such as wood chips, straw, etc.) is transported to the combustion chamber of the chain grate boiler through the feeding system.
Combustion Process: Fuel is ignited in the combustion chamber while the chain boiler's chain system starts operating. The fuel is gradually propelled forward by the movement of the chain, simultaneously burning within the 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 smoke generated from combustion is channeled through the flue system of the combustion chamber and exhausted into the chimney. During the flue gas emission process, treatment by flue gas purification equipment can be utilized to reduce the particulate matter and gas pollutants in the emissions.
Heat Recovery: The heat generated from 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 boiler typically features 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, chain biomass chain boilers gradually feed biomass fuel into the combustion chamber through a chain system for combustion. The thermal energy is transferred to water or other working substances through a heat exchanger, achieving heat recovery and utilization. These boilers offer high combustion efficiency and strong fuel adaptability, and are widely used in heating, industrial heating, and other fields.

Biomass fuel boilers may encounter the following issues during operation:
Fuel quality inconsistency: The quality of biomass fuel is affected by factors such as raw material source, processing methods, and storage conditions, leading to inconsistent fuel quality. Inconsistent fuel quality may impact combustion efficiency and the stable operation of boilers.
Ash disposal issue: Biomass fuel produces a large amount of ash during combustion, including waste, ash, and unburnt materials. The handling and disposal of ash may pose environmental pollution and cost issues.
High-Temperature Corrosion: Ash and elements like chlorine in biomass fuels are prone to cause corrosion at high temperatures, damaging the metal components of boilers. Measures need to be taken to protect and treat high-temperature corrosion issues.
Low combustion efficiency: Biomass fuel has different combustion characteristics from traditional fossil fuels, which may result in lower combustion efficiency. It is necessary to optimize the combustion system and control strategies to enhance combustion efficiency and reduce energy waste.
Gas emissions from combustion: The combustion of biomass fuel produces certain emissions, such as carbon dioxide, nitrogen oxides, and particulates. These emissions have an impact on the environment and air quality, necessitating appropriate control measures.
Transportation and storage costs: The transportation and storage costs for biomass fuels are high, especially for areas far from the supply source. This may increase the operating costs for biomass fuel boilers.
In summary, biomass fuel boilers face issues such as inconsistent fuel quality, ash and slag disposal, and high temperatures.
