2023-07-04

Biomass hot water boilers, as an environmentally friendly and renewable energy equipment, are widely used in industrial and residential fields. It utilizes the thermal energy generated by biomass fuels and transfers it to hot water heating systems or industrial production processes through a cyclic approach. What are the common circulation methods and applications of biomass hot water boilers? Today, Xinli Boiler will briefly introduce them to customers to better understand and utilize this energy equipment.

1、 Natural circulation of biomass hot water boilers

Natural circulation of biomass hot water boilers is one of the simplest and most basic circulation methods. It uses the density difference of hot water to generate Natural convection. Hot water forms upward flow in the boiler, and cold water drops and enters the heating area. This circulation method has a simple structure and does not require additional circulation pumps, making it suitable for small biomass hot water boilers and low-power applications.

2、 Forced circulation of biomass hot water boiler

Forced circulation uses a circulating pump to forcefully promote the circulation of hot water, in order to improve the flow rate and circulation efficiency of hot water. The circulating pump draws hot water out of the boiler, delivers it through pipelines to the hot water heating system or industrial production process, and then returns it to the boiler heating area. The forced circulation method is suitable for high-power biomass hot water boilers and long-distance transportation, ensuring a stable hot water supply.

3、 Gravity circulation of biomass hot water boiler

Gravity circulation utilizes natural gravity to achieve the circulation of hot water through the rise and fall of pipelines. Hot water is generated in the ascending pipeline and then passes through the heating system or industrial production process, returning to the boiler through the descending pipeline. The gravity circulation mode does not need a circulating pump, and is suitable for small biomass hot water boilers and high altitude Hydronics.

There are various circulation methods for biomass hot water boilers, and suitable circulation methods can be selected based on specific application needs and conditions. Natural circulation, forced circulation, and gravity circulation have their own characteristics and are suitable for biomass hot water boiler systems of different scales and requirements.

Heat-transfer fluid boiler: advantages in the field of clean energy

The Heat-transfer fluid boiler uses Heat-transfer fluid as the heat transfer medium, and the commonly used Heat-transfer fluid includes hot oil and hot water. The fuel generates high temperature heat energy through combustion, and then transfers the heat energy to the Heat-transfer fluid through the heat exchanger. Heat-transfer fluid flows in the boiler system, transfers heat energy to other equipment or converts energy, which has unique advantages in the field of clean energy:
