The feeding system of biomass pellet fuel boilers typically includes the following components:
Feeding Conveyance System: Designed to transport biomass pellet fuel from storage areas or supply sources to the boiler fuel hopper. The feeding conveyance system can utilize screw conveyors, chain conveyors, belt conveyors, etc., with the appropriate conveyance method chosen based on actual conditions.
Fuel Storage: Used for storing biomass pellet fuel, typically located at the bottom of the boiler. The design of the fuel storage should consider the fuel capacity and stable supply to ensure continuous operation of the boiler.
Feed Control System: Used to regulate the rate and quantity of fuel supply to meet the thermal load requirements of the boiler. The feed control system typically includes the start/stop control of the feed conveyor and the adjustment of feed quantity.
Fuel Crushing System (Optional): For some larger biomass pellet fuels, crushing may be required to better accommodate the boiler's combustion requirements. The fuel crushing system typically includes crushers, jaw crushers, and other equipment.
Fuel Pretreatment System (Optional): For biomass pellet fuels containing higher humidity or impurities, pretreatment such as drying, screening, and decontamination may be required to enhance combustion efficiency and stability.
When designing and selecting the feed system for biomass pellet fuel boilers, factors such as the fuel characteristics, supply volume, and combustion requirements must be considered. At the same time, ensure the stability, reliability, and safety of the feed system to guarantee the boiler's...

The DZL type rapid assembly biomass boiler is a common model of biomass boiler, featuring the following characteristics:
Rapid Installation: The DZL type quick-install biomass boiler features modular design, with the boiler body and equipment pre-assembled in the factory. On-site, only simple connection and adjustment are required, significantly reducing installation time and project duration.
High combustion efficiency: Features a special combustion chamber design and combustion system, ensuring complete combustion of biomass fuel within the furnace, resulting in high thermal efficiency. Additionally, equipped with an economizer and flue gas recirculation device to further enhance thermal efficiency.
Automation Control: The DZL-type quick-assembly biomass boiler is equipped with an automated control system, enabling control and monitoring of the combustion process. Through a PLC controller and a touch screen, parameters such as fuel supply, air supply, and combustion temperature can be adjusted to ensure the stable operation of the boiler.
Multiple Fuel Adaptability: The DZL quick-assembly biomass boiler is suitable for various biomass fuels such as sawdust and straw, etc. Different fuels can be chosen according to actual conditions, enhancing the substitutability and flexibility of the fuel.
Environmental Protection and Energy Saving: The DZL type quick-assembly biomass boiler uses biomass fuel, resulting in relatively low emissions of waste gas and slag during combustion, and low levels of pollutants in the combustion emissions. Biomass fuel inherently features low sulfur and low nitrogen, and the slag produced after combustion can be reused as organic fertilizer or biomass fuel, reducing environmental pollution.

The methods for setting the pressure of biomass hot water boilers mainly include the following:
Regular Discharge: Regularly discharge excess water from the boiler to maintain normal working pressure. Discharging excess water helps prevent excessive internal pressure in the boiler, ensuring stable operation.
Timed Operations: Perform operations at regular intervals based on the boiler's water level to maintain normal working pressure. Pay attention to the control amount to avoid overfilling and resulting in excessive boiler pressure.
Pressure Control System: The installation of a pressure control system allows for real-time monitoring of the boiler's pressure through sensors and controllers, and automatic adjustment based on set values. In the event that the boiler pressure exceeds the set value, the control system will automatically reduce fuel supply or exhaust excess water to maintain a stable working pressure for the boiler.
Pressure Regulator: Install a pressure regulator on the boiler's inlet water pipe. By adjusting the valve opening, control the water inflow to maintain the boiler's stable operating pressure. The pressure regulator can automatically adjust to the set value, keeping the boiler pressure within the appropriate range.
Pressure Regulator: Install a pressure regulator in the boiler's combustion system to control the steam pressure of the boiler by adjusting the combustion intensity of the burner. The pressure regulator can automatically adjust the working state of the burner according to the set value to maintain a stable working pressure for the boiler.
The above are common methods for setting the pressure of biomass hot water boilers. According to actual conditions and requirements, you can choose an appropriate pressure setting method to maintain the stable working pressure of the boiler.

The emission characteristics of biomass fuel boiler flue gases primarily include the following aspects:
Particulate Emissions: During the combustion process of biomass fuel boilers, particulates are produced, including visible dust and fine particles. The amount of particulate emissions is related to fuel characteristics, combustion temperature, and combustion equipment factors. Generally, particulate emissions from biomass fuel boilers are lower than those from coal boilers, but still require treatment through dust removal equipment.
(SO2) Emissions: The content of SO2 in biomass fuels is low, hence the SO2 emissions from biomass fuel boilers are generally low. However, in certain cases, such as using waste materials as fuel, SO2 emissions may increase. To control SO2 emissions, measures like combustion control and desulfurization units can be implemented.
NOx emissions: The NOx emissions of biomass fuel boilers are related to fuel characteristics, combustion temperature, and combustion equipment factors. Biomass fuel has a higher nitrogen content, which generates a certain amount of NOx during combustion. To control NOx emissions, measures such as low-NOx combustion technology, combustion control, and denitration equipment can be adopted.
CO Emissions: Carbon monoxide (CO) emissions from biomass fuel boilers are typically low due to the relatively complete combustion process of biomass fuel. However, under conditions of incomplete combustion or unstable burning, CO emissions may increase. To control CO emissions, it is necessary to ensure a thorough and stable combustion process.
Volatile Organic Compounds (VOCs) Emissions: The amount of VOCs emitted by biomass fuel boilers is related to the fuel characteristics and combustion conditions. Some biomass fuels contain volatile organic compounds.
