Biomass boilers can be broadly categorized into two types based on their applications:
Biomass Hot Water Boilers: Biomass hot water boilers are primarily used for heating and hot water supply. They transfer heat energy to water by burning biomass fuel, producing hot water. This type of boiler is widely used in heating and hot water systems in homes, office buildings, schools, hotels, and other locations.
Biomass Steam Boilers: Biomass steam boilers are primarily used for steam supply in industrial production processes. They generate high-pressure steam at high temperatures by burning biomass fuel, which is utilized to power machinery, heating, and processing in various industrial applications. This type of boiler is commonly found in industries such as pulp and paper, food processing, and chemical manufacturing.
These two types of biomass boilers differ in principle and design, making them suitable for various application scenarios. Whether for hot water or steam boilers, they utilize the thermal energy from biomass fuel, achieving the utilization of renewable energy and featuring environmental protection and energy conservation.

When selecting an appropriate atmospheric pressure hot water boiler, consider the following factors:
Heating Area: First, determine the size of the area that requires heating, which will decide the required heat output of the hot water boiler. Generally, the larger the heating area, the greater the heat output needed.
Heat Load Calculation: Conduct a heat load calculation, taking into account the insulation performance of the heating area, indoor temperature requirements, and external climatic conditions, to determine the required heat power. You may request a heat load calculation to ensure the selected hot water boiler meets the heating needs.
Fuel Type: Atmospheric pressure hot water boilers can use various fuels such as gas, oil, etc. Select the appropriate fuel type based on local fuel supply conditions and cost considerations.
Boiler Efficiency: Focus on the energy efficiency of hot water boilers and choose products with higher efficiency. High-efficiency hot water boilers can provide better heating effects while reducing energy consumption and operational costs.
Boilers and Quality: Opt for hot water boilers produced by reputable manufacturers to ensure reliable product quality and comprehensive after-sales service.
Safety and Environmental Protection: Focus on the safety and environmental performance of hot water boilers, selecting products with safety protection features and low emissions.
Budget Considerations: Select a suitable hot water boiler based on budget constraints. In addition to the purchase cost, consider the ongoing operational and maintenance costs.
Considering the above factors, a suitable atmospheric pressure hot water boiler can be selected to meet heating requirements, while achieving good performance in terms of energy efficiency, safety, and environmental protection. It is recommended to consult with professionals or hot water boiler experts during the selection process.

Reducing emissions of nitrogen oxides (NOx) from biomass boilers can be achieved through the following measures:
Combustion Control Technology: Utilizes advanced combustion control techniques such as low nitrogen combustion technology. By optimizing the combustion process, controlling the combustion temperature and oxygen concentration, the formation of nitrogen oxides is reduced. Methods such as staged combustion and optimized combustion chamber design can be employed to lower combustion temperatures and extend combustion times, thereby decreasing nitrogen oxide emissions.
SNCR Technology: Selective Non-Catalytic Reduction (SNCR) technology involves injecting a reductant, such as urea solution, into the combustion process, which reacts with nitrogen oxides to convert them into nitrogen and water. This technique can reduce the formation and emission of nitrogen oxides during combustion.
SCR Technology: Selective Catalytic Reduction (SCR) technology is a nitrogen oxide control method. By injecting urea solution into flue gas and passing it through a catalyst, nitrogen oxides are converted into nitrogen and water. SCR technology achieves nitrogen oxide removal at lower temperatures, suitable for large biomass boilers.
Flue Gas Recirculation (FGR): FGR technology recycles a portion of flue gas back into the boiler combustion chamber, reducing combustion temperature and oxygen concentration, thereby minimizing the formation of nitrogen oxides. This technique can control nitrogen oxide emissions by adjusting the recirculation ratio.
Fuel selection and pretreatment: Choosing low nitrogen fuels, such as low nitrogen biomass fuel, can reduce the formation of nitrogen oxides. Moreover, for biomass fuels with high nitrogen content, pretreatment measures like drying and gasification can be taken to decrease the formation of nitrogen oxides during combustion.
Regular maintenance and cleaning: Regular maintenance and cleaning of biomass boilers are essential to keep burners, heat exchangers, and other components clean and operating efficiently. Cleaning the combustion chamber and heat exchangers can reduce soot buildup, enhance thermal conductivity, and lower nitrogen oxide emissions.
By integrating the aforementioned measures, nitrogen oxide emissions from biomass boilers can be effectively reduced, achieving the goals of environmental protection and energy conservation. The specific measures to be chosen should be based on the characteristics of the boiler, operating conditions, and emission requirements.

Chain biomass boiler is a common type of biomass boiler, its working principle and process are as follows:
Fuel Supply: Biomass fuel (such as wood chips, straw, etc.) is conveyed 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.
Smoke Emission: Flue gases produced by combustion are channeled through the flue system of the combustion chamber and released into the chimney. During the smoke emission process, treatment with flue gas purification equipment can reduce the emitted particulate matter and gas pollutants.
Recovery of Heat Energy: The heat generated from combustion is transferred to water or other working fluids through the heat exchanger of the boiler, raising their temperature. After the heat is recovered, 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 operation and performance of the boiler.
Overall, the biomass chain grate boiler gradually feeds biomass fuel into the combustion chamber through a chain system for burning. The thermal 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.
