Fully automatic biomass boiler systems commonly use a make-up water pump to maintain constant pressure, which is a typical water supply method. The specific working principle is as follows:
Supply Pump: The fully automatic biomass boiler is equipped with a supply pump, which is used to pump water from the water source (such as a water tank or municipal water supply) into the boiler's water supply system.
Pressure Regulation: The feed water pump employs 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 feed water pump will automatically activate, replenishing water into the supply system to increase the system pressure.
Pressure Control: The supply pump will control according to the set pressure range. When the system pressure reaches the set value, the supply pump will cease operation to prevent excessive pressure.
Automation Control: The water supply system of an 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 feed pump to ensure the stable operation of the water supply system.
By employing a pressure-regulating pump system, the fully automatic biomass boiler can achieve automated control of the water supply system and stable water supply, ensuring the boiler operates normally and safely. This method can be adjusted and optimized according to actual needs, enhancing water supply and energy utilization efficiency.

During operation, biomass thermal oil heaters are prone to scaling due to the high temperature of the thermal oil and long-term use. To prevent the formation of scale, manufacturers of biomass thermal oil heaters typically take the following measures:
Selecting the Appropriate Thermal Conductive Oil: Manufacturers choose thermal conductive oils with good thermal stability and antioxidant properties to minimize scaling. The selection of thermal conductive oil should be reasonably matched according to the actual operating conditions and requirements.
Control oil temperature and flow rate: Manufacturers will rationally control the temperature and flow rate of the thermal oil based on its properties and operational requirements. Excessive temperature and rapid flow can easily lead to scale formation, so proper adjustment is necessary.
Regular Cleaning and Maintenance: Manufacturers recommend users to regularly clean and maintain biomass thermal oil heaters to remove scale buildup. Cleaning agents and equipment that can be used during the process, as well as the scale removal, will restore the normal operation of the thermal oil heater.
Install filters and descaling devices: Manufacturers may install filters and descaling devices in biomass thermal oil boilers to filter out impurities and scale in the thermal oil. These devices effectively prevent scale formation, extending the service life of the thermal oil boiler.
Regular Monitoring and Analysis: Manufacturers may recommend that users regularly monitor and analyze the properties and quality of the thermal oil to promptly identify any abnormalities and take appropriate measures.
