ZOZEN Biomass Boiler Fuel Consumption: A Sustainable Solution

The demand for biomass boilers is on the rise globally, as they provide a sustainable and environmentally friendly solution for heat generation. ZOZEN, in collaboration with the technical team and Shanghai Jiao Tong University, has developed biomass boilers that boast high thermal efficiency, adequate output, stable combustion, easy on-site installation, simple operation, short construction cycle, and low costs. Notably, ZOZEN biomass boilers are renowned for their low biomass boiler fuel consumption.

Calculating Biomass Boiler Fuel Consumption:
The consumption of biomass fuel is directly related to its energy content. For instance, in biomass boilers burning wood, the fuel consumption is associated with the heat value of the wood, usually measured in terms of energy content per unit volume or weight. Let’s consider an example of a biomass boiler with a steam production capacity of 1 t/h, requiring a heat absorption of 600,000 KCal per hour. If the heat value of a particular wood is 4,000 Kcal/kg, the biomass boiler fuel consumption would be 600,000/4,000/88% = 171 kg. Therefore, ZOZEN biomass boilers are known for their low biomass boiler fuel consumption.

ZOZEN Biomass Boiler Product Range:
ZOZEN offers three series of biomass steam boilers: DZL series horizontal chain grate boilers, SZL series double drum vertical chain grate boilers, and SHL series biomass bulk steam boilers. Let’s focus on the DZL and SZL series, which have a wide fuel adaptability and can utilize various biomass fuels such as pellets, wood chips, palm shells, and straw.

DZL Series Single Drum Biomass Steam Boiler:
Thermal capacity: 2 – 10 t/h
Equipped with threaded smoke tubes and advanced manufacturing techniques, the boiler ensures efficient heat transfer and improved thermal efficiency, resulting in low biomass boiler fuel consumption.
Biomass fuels, with their high volatiles and low ash content, leave minimal residue on the grate surface, subjecting it to high-temperature radiation. ZOZEN selects suitable high-temperature-resistant grate materials to enhance reliability.

DZL Series Three Drum Biomass Steam Boiler:
Thermal capacity: 15 – 40 t/h
The furnace walls are lined with water-cooled panels and increased furnace volume, effectively controlling the temperature below 850℃, reducing the generation of NOx, and providing excellent environmental performance.
The structure resolves the issue of ash accumulation in traditional double drum boilers. With two drums placed on the lower sides and an ash hopper in the middle, dust settles directly into the bottom ash hopper.
ZOZEN designs different feeding systems according to the characteristics of different biomass fuels, effectively improving the overall efficiency and achieving low biomass boiler fuel consumption.

SZL Series Double Drum Biomass Steam Boiler:
Thermal capacity: 6 – 35 t/h
With optimum excess air and appropriate oxygen levels in each combustion zone, the boiler ensures complete combustion of 70% of the volatile matter generated during biomass drying and pyrolysis, resulting in low biomass boiler fuel consumption. Complete carbon combustion minimizes black smoke and pollutant emissions.
A flame-retardant baffle (lock feeder) is installed at the furnace inlet, providing excellent sealing and flexibility. It prevents backfiring in case of boiler malfunctions or operator errors, ensuring the prevention of biomass self-ignition in the fuel hopper.

ZOZEN’s Collaboration with the Ivorian Paper Industry:
After extensive market research and rigorous selection, a leading paper company in Ivory Coast, Africa, chose ZOZEN’s DZL series biomass boilers as their primary energy source. With wood chips as the main fuel, these boilers offer high efficiency, low biomass boiler fuel consumption, and environmental friendliness, providing strong support for the company’s sustainable development. Although the company faced some installation challenges, they maintained constant communication with ZOZEN’s after-sales personnel, who patiently addressed their concerns and provided detailed operation and maintenance guidelines. This ensured the safe and stable operation of their biomass boilers.

Conclusion:
ZOZEN’s biomass boilers are in high demand globally due to their low biomass boiler fuel consumption, making them an ideal choice for sustainable and efficient heating solutions. With a diverse product range, including the DZL and SZL series, ZOZEN ensures adaptability to various biomass fuels, high thermal efficiency, and reliable performance. By choosing ZOZEN, companies can contribute to a greener future while meeting their heating needs efficiently.
