The biomass boiler body is typically composed of the following components, each serving a specific function:
Furnace Chamber: The furnace chamber is the area where biomass fuel is burned, serving as the space for combustion and heat exchange. The fuel within the chamber releases heat energy during the combustion process, while flue gases exchange heat with water through the furnace chamber.
Chimney Flue: The flue is a passage for smoke gas flow, guiding the exhaust gases from the furnace to the chimney for emission. The smoke gas inside the flue exchanges heat with the boiler's water, transferring heat from the gases to the water, thereby improving thermal efficiency.
Boiler Drum: The boiler drum is the main component that holds water and steam, where water is heated to transform into steam. The drum is equipped with water level control devices to regulate the water level, ensuring the safe operation of the boiler.
Grate: A grate is a device used to support and burn biomass fuel, its function being to evenly distribute the fuel in the furnace chamber and provide air supply to promote the combustion process.
Superheater: A superheater is a device that heats the saturated steam in a boiler to increase its temperature and pressure. It transfers heat from the flue gas to the steam through heat exchange between them.
Condenser: A condenser is a device used to condense steam into water, releasing the heat from the steam. By exchanging heat with a cooling medium (such as cold water), a condenser converts the heat from the steam into thermal energy, enhancing thermal efficiency.
Chimney: A chimney is a conduit for releasing flue gases into the atmosphere, serving the purpose of exhaust.

The pressure maintenance methods for biomass hot water boilers mainly include the following:
Natural Circulation Pressure Regulation: Natural circulation pressure regulation refers to the circulation of hot water to the heating system through natural convection within the boiler. Under the natural circulation pressure regulation method, there is a significant difference in elevation between the supply and return water pipes of the boiler, achieving natural circulation through the density difference of the hot water. This method is suitable for small biomass hot water boilers, characterized by simplicity and economy.
Forced Circulation Constant Pressure: This method involves using a circulating pump to force hot water to circulate through the heating system. Under the forced circulation constant pressure method, the boiler provides sufficient water pressure through the circulating pump to ensure smooth flow of hot water. This approach is suitable for large-scale biomass hot water boilers and boasts stability and reliability.
Micro-positive Pressure Constant Pressure: Micro-positive pressure constant pressure maintains a slight positive pressure in the boiler system to ensure stable circulation of hot water. Under this method, the pressure in the boiler system is slightly higher than atmospheric pressure, driving the circulation of hot water through the pressure difference. This approach is suitable for situations requiring higher heating temperatures and greater heating distances.
Above are the common methods of pressure setting for biomass hot water boilers. Depending on specific usage requirements and system design, an appropriate pressure setting method can be chosen to ensure the normal operation and heating effect of the hot water boiler.

Control methods for biomass boiler combustion systems can include the following aspects:
Fuel Supply Control: Regulate the supply quantity and speed of biomass fuel to ensure stable fuel supply. This can be achieved by adjusting the feed speed or turning on/off the feeder.
Air Supply Control: Regulate the air supply during the combustion process to ensure complete fuel combustion. This can be achieved by adjusting the speed or on/off of the fan.
Combustion Temperature Control: Monitors the temperature within the combustion chamber and adjusts it according to the set values. The combustion temperature can be controlled by adjusting the air supply or fuel supply to the combustion chamber.
Combustion Process Monitoring: Monitors parameters during the combustion process, such as combustion temperature and chamber pressure, to real-time monitor the combustion status and adjust accordingly based on the monitoring results.
Oxygen Content Control: By monitoring the oxygen content within the combustion chamber and adjusting it to the set value, complete combustion of the fuel is ensured. This can be achieved by installing an oxygen content sensor and regulating the air supply.
Ash cleaning system control: Regulates the operation of ash cleaning equipment, promptly burning off the ash in the combustion chamber to ensure combustion efficiency and the normal operation of the system.
Above are some common control methods for biomass boiler combustion systems. Specific control strategies and methods will vary depending on the type of boiler and system design.

Biomass boilers typically include the following main components:
Combustion chamber: The area for burning biomass fuel, providing the space and oxygen required for combustion.
Grate: A metal grid located at the bottom of the combustion chamber, used to support fuel and facilitate the flow of gases and slag during the combustion process.
Combustion System: Includes the fuel supply system, air supply system, and ignition system, designed to control the supply of fuel and air for the combustion process.
Flue Gas Treatment System: Comprises flue gas purification equipment such as dust collectors, desulfurization, and denitrification units, designed to purify flue gases produced by combustion and reduce environmental pollution.
Boiler pipeline system: Includes water pipes, steam pipes, and flue gas pipes, etc., for transmitting heat and flue gas.
Heat Exchanger: Used to transfer the heat energy produced by combustion to the working medium, such as water or steam, to achieve energy conversion.
Control System: Includes automatic control equipment, sensors, and instruments for monitoring and controlling the boiler's operational status, ensuring safety and operation.
Equipment: Includes water supply systems, sewage systems, ash and slag handling systems, and fuel storage systems, etc., to provide the necessary functions for boiler operation.
These units collectively form the basic structure of biomass boilers, facilitating the combustion of biomass fuel and the energy conversion process. The specific units and configurations will vary depending on the type, scale, and application requirements of the boiler.
