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

Biomass hot water boilers may produce scale during operation, affecting the boiler's heat transfer and efficiency. Here are some methods to reduce scale:
Fuel Selection: Choose high-quality biomass fuel such as sawdust, straw, etc. Avoid using fuel with excessive impurities and ash to reduce soot generation.
Combustion Adjustment: Properly regulate combustion parameters such as fuel supply, oxygen supply, and combustion temperature. Both excessively high and low combustion temperatures can lead to soot formation. Maintaining an appropriate combustion temperature helps reduce soot buildup.
Clean Combustion Chamber: Regularly clean the combustion chamber to remove ash and dirt generated during the combustion process. Use appropriate tools and cleaning agents to ensure the chamber remains clear and clean.
Heat Exchanger Cleaning: Regularly clean heat exchangers, especially those on the flue side. The flue gas produced during combustion may contain particles and slag, which can adhere to the surface of the heat exchanger, affecting heat transfer efficiency. Using appropriate cleaning methods, such as mechanical or chemical cleaning, can reduce the accumulation of dirt.
Water Treatment: Proper water treatment for boiler feed water to prevent impurities and sediments from settling inside the boiler. Methods such as water softening, deoxygenation, and scale removal can be employed to maintain clean and stable water supply.
Regular Maintenance: Perform regular maintenance and inspections on the boiler, including cleaning and replacing critical components. Early detection and resolution of dirt issues can prevent further accumulation and affect the normal operation of the boiler.
Please note that specific methods for reducing dirt may vary depending on the model and manufacturer of biomass hot water boilers. It is recommended to refer to the manufacturer's operation manual and guidelines to adopt appropriate dirt reduction measures based on the specific situation.

Water level control during the operation of biomass boilers is crucial, primarily to ensure the safe and normal operation of the boiler. The following are general methods of water level control:
Water Level Gauge Monitoring: Biomass boilers commonly install water level gauges to monitor the water level inside the boiler. These gauges can be glass tube gauges, electric gauges, or pressure gauges, among others. By reading the gauge, one can gain real-time insights into the water level inside the boiler.
Water Level Controller: Biomass boilers typically come equipped with a water level controller for automatic water level regulation. The controller adjusts the water level inside the boiler by controlling the operation of devices like feed water pumps or drainage valves, based on the set water level range.
Water Supply Control: When the boiler water level is too low, the water level controller sends a signal to start the feed pump, replenishing water into the boiler to maintain the water level within a safe range. Water supply control needs to be adjusted according to the actual needs of the boiler and changes in water level.
Wastewater Control: When the boiler water level is too high, the water level controller sends a signal to activate the drain valve, expelling the excess water to maintain the level within a safe range. The wastewater control also needs to be adjusted according to the actual requirements of the boiler and the changes in water level.
Alarm Protection: Should the boiler water level exceed the high limit or fall below the low limit, the water level controller will emit an alarm signal to alert the operator to take action. Additionally, the boiler should be equipped with a water level protection device that automatically shuts off the burner's gas supply when an abnormal water level is detected, ensuring the safety of the boiler.
Note that the control of water level must be based on the specific design of the boiler and the operation manual to ensure proper and safe operation. Additionally, regularly inspect and maintain devices such as the water level gauge and water level controller to ensure their normal operation and accuracy.

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 delivered to the combustion chamber of the chain boiler via the feeding system.
The combustion process: The fuel is ignited in the combustion chamber while the chain boiler's chain system starts operating. The fuel is gradually pushed 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 flue gas produced by combustion is channeled through the flue system of the combustion chamber and discharged into the chimney. During the flue gas emission process, treatment can be conducted using flue gas purification equipment 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 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, chain biomass chain boilers gradually feed biomass fuel into the combustion chamber through a chain system for burning. The heat energy is transferred to water or other working substances via heat exchangers, 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.
