- In countries with a variety of agricultural and forestry waste products like rice husk, sawdust, cashew nut shell, chopped wood, coffee husk... with large and stable outputs like Vietnam, the choice of "Biomass-fired Fluidized Bed Boilers" is the most optimal solution, offering the highest economic efficiency among all current boiler investment options. Fluidized bed boiler technology, with high efficiency due to its special combustion method combined with the low cost of fuel from agricultural and forestry waste, makes "Biomass-fired Fluidized Bed Boilers" popular due to the lowest steam production cost compared to traditional boilers like chain grate boilers, fixed grate boilers, and oil-fired boilers.
- Especially, the rapid steam generation capability of "Biomass-fired Fluidized Bed Boilers" is suitable for production systems with continuously changing load demands such as in the brewing, beverage, and food industries. Moreover, the system is fully automated with PLC-SCADA, significantly saving operational labor costs with only 2 workers per shift for systems with capacities from 8 to 15 tons.
- PLC-SCADA control technology also allows for remote connection and control via RS485 and the internet, facilitating remote monitoring, control, and repair, bringing convenience and high efficiency. The automatic fuel adjustment system based on pressure and linear method optimizes fuel consumption while reducing greenhouse gas emissions.
- DIVI Group's boilers can use a variety of fuels like chopped wood, pellets, cashew nut shell, rice husk, sawdust with high efficiency and stable steam generation. The system is designed with a multi-stage heat recovery system including a water pre-heater and an air pre-heater, minimizing heat loss and increasing efficiency up to 89%.
- Fan systems are precisely designed and operate at low speeds to minimize wear from dust, are machined with CNC, and use bearings from Japan and Germany to ensure smooth and durable operation. DIVI Group guarantees boiler product quality with a total system warranty of up to 60 months from handover, thereby giving customers peace of mind for long-term use without worrying about high repair costs.

Other Product
Biomass-fired Thermal Oil Boiler
"Biomass-fired Thermal Oil Boilers" manufactured by DIVI Group have the same advantages as the "Fluidized Bed Biomass Boilers" technology. The only difference is the medium used by the Thermal Oil Boiler is heat transfer oil, whereas the Fluidized Bed Boiler uses water vapor.
Liquid fuel-fried Boiler
For high hygiene requirements and limited installation space, but where steam production cost is not a critical issue, "Liquid fuel-fried Boiler" are a suitable choice.
