Chain生物质 boiler, also known as chain grate biomass boiler, is a special type of biomass boiler. It uses a chain grate as the fuel conveying and combustion device.
The chain grate consists of a series of interconnected chains, with evenly spaced grate plates distributed along them. Fuel is transported from one end to the other of the furnace chamber through the movement of the chain grate, where it also burns simultaneously.
The working principle of the chain biomass boiler is: fuel is evenly distributed on the chain grate, gradually moving towards the exit of the furnace as the chain moves. Inside the furnace, the fuel is thoroughly mixed with air, releasing heat energy through combustion reactions. Simultaneously, the design of the grate plates and the movement of the chain ensure even and complete combustion of the fuel.
Chain biomass boiler features include:
Adaptable: Chain grate stokers can accommodate various biomass fuels such as sawdust and straw, demonstrating strong fuel adaptability.
High combustion efficiency: The design of the chain grate ensures uniform and complete combustion of the fuel, enhancing the combustion efficiency.
Stable Operation: The reciprocating movement of the grate in the chain grate boiler is stable, ensuring reliable fuel feeding and combustion process, with high stability in the boiler's operation.
Suitable for Large Capacity Boilers: Chain biomass boilers are designed for large-scale boiler systems, meeting the requirements of the industrial and heating sectors.
Chain biomass boilers are widely used in the field of biomass energy utilization, effectively utilizing biomass fuel, and achieving sustainable energy use.

Biomass boilers promote environmental protection in the following aspects:
Renewable Energy Utilization: Biomass boilers use biomass fuel, such as wood chips, straw, wheat straw, fruit shells, etc., which are renewable resources. Compared to fossil fuels, the combustion of biomass fuel releases less carbon dioxide, resulting in a smaller impact on climate change.
Reducing greenhouse gas emissions: The carbon dioxide produced during the combustion process of biomass boilers can be reabsorbed through the regeneration process of biomass, forming a closed loop. This helps to decrease greenhouse gas emissions and has a cumulative effect on slowing down climate change.
Low Pollution Emissions: The combustion process of biomass boilers produces flue gas with relatively low pollutant emissions. By means of reasonable combustion adjustment and supplementary pollution control equipment such as dust collectors and nitrogen oxide control devices, the emissions of pollutants like particulates and nitrogen oxides in the flue gas can be further reduced.
Recycling Waste Materials: Biomass boilers can utilize waste materials and by-products as fuel sources, such as crop straw and wood processing waste. This approach enables the recycling of waste, thereby reducing issues related to waste storage and disposal.
Energy Efficiency Enhancement: The combustion process of biomass boilers can be improved through technologies such as heat recovery and waste heat utilization, enhancing energy utilization efficiency. This aids in reducing energy consumption and diminishing reliance on traditional energy sources.
Overall, biomass boilers, as a renewable energy utilization technology, offer advantages such as low carbon and pollution emissions, as well as waste recycling, contributing positively to environmental protection and sustainable development.

Fully automatic biomass boiler uses a make-up water pump to maintain pressure, which is a common water supply method. The specific working principle is as follows:
Supplemental Pump: The fully automatic biomass boiler is equipped with a supplemental pump, which is used to draw water from a water source (such as a water tank or municipal water supply) and pump it into the boiler's supply system.
Pressure Control Method: The make-up water pump utilizes a constant pressure method, which involves setting up a pressure sensor or controller in the boiler water supply system to monitor the pressure. When the pressure of the water supply system falls below the set value, the make-up water pump automatically starts, replenishing water to the supply system and increasing the system pressure.
Pressure Control: The feed pump will control the pressure based on the set pressure range. The feed pump will cease operation when the system pressure reaches the set value to avoid excessive pressure.
Automation Control: The water supply system of a fully automatic biomass boiler is typically equipped with an automated control system that can intelligently manage based on the boiler's operating status and requirements. For instance, when the boiler needs to replenish water, the control system will automatically activate the feedwater pump to ensure the stable operation of the water supply system.
By utilizing a constant pressure supply pump method, the fully automatic biomass boiler can achieve automated control and stable water supply of the water system, ensuring the normal operation and safety of the boiler. This approach can be adjusted and optimized according to actual needs, enhancing water supply and energy utilization efficiency.

Biomass refers to renewable energy sources derived from organic materials such as plants, animals, and microorganisms. It includes wood, straw, waste crops, food scraps, and municipal solid waste, among others. Biomass has a wide range of sources and types and is a renewable energy that can substitute for fossil fuels.
A biomass boiler is a specialized equipment designed for burning biomass fuel. It combusts biomass fuel to produce high-temperature, high-pressure thermal energy, which is used for heating, power generation, or other industrial processes. Biomass boilers typically use granular, pelletized, or chipped biomass fuel, releasing thermal energy through the combustion process.
The advantages of biomass boilers include:
Renewable Energy: Biomass is a renewable energy source with lower carbon emissions and environmental impact compared to fossil fuels.
Diversity: A wide variety of biomass fuels can be utilized from plant and animal waste and by-products, enhancing resource utilization efficiency.
Environmental Friendliness: The carbon dioxide produced during biomass combustion can be absorbed by plants, forming a cycle that reduces air pollution.
Economic Efficiency: Biomass fuel is relatively more economical.
