Meet ZOZEN’s High-Efficiency Coal Burning Boiler Systems

May 24, 2024

Introduction to Coal Burning Boiler Systems
A coal burning boiler system operates by burning coal to generate heat, which is then used to convert water into steam. This steam can be used for a variety of industrial applications, ranging from power generation to heating processes. ZOZEN, a seasoned provider of coal burning boiler systems, offers solutions that are not only safe and energy-efficient but also easy to maintain. By choosing ZOZEN’s coal burning boiler systems, enterprises can significantly reduce operational costs and enhance efficiency.

ZOZEN’s Premium Coal Burning Boiler Systems
ZOZEN offers a range of high-quality coal burning boiler systems, categorized into four main series: the DZL series, SZL series, SHL series, and DHL series. These systems, with capacities ranging from 2 to 75 tons per hour, are suitable for various scales and industrial applications. ZOZEN’s coal burning boiler systems are adaptable to a wide range of coal types, including bituminous coal, anthracite, and lean coal. The combustion air system (base) features independent compartments and a scientifically sealed structure to minimize boiler heat loss. Additionally, the rational selection of fan parameters ensures precise air distribution, reducing the oxygen content in the flue gas and thus lowering exhaust loss to improve combustion efficiency.

Collaboration with a Leading Feed Company in Pakistan
To reduce operational costs, a renowned feed company in Pakistan decided to mix rice husk with coal as boiler fuel. This approach not only repurposed rice husk waste, promoting the recycling of biomass resources but also enhanced the company’s economic benefits. Addressing the client’s specific needs, ZOZEN custom-designed an SZL series steam boiler system tailored to the unique characteristics of the “lignite + rice husk” fuel combination. This involved optimizing the feeder, grate width, and length to match the client’s production requirements. The resulting system boasts thermal efficiency over 5% higher than typical industry boiler systems, achieving efficient heat conversion. The client praised ZOZEN for its responsibility and simplicity in cooperation, noting that ZOZEN’s assistance significantly reduced their operational costs.

ZOZEN’s Commitment to Innovation
For over thirty years, ZOZEN has been dedicated to the research, design, manufacture, and service of boilers. Collaborating with esteemed institutions such as Tsinghua University, Xi’an Jiaotong University, and Shanghai Jiaotong University, ZOZEN has studied the combustion characteristics of coal and biomass fuels.
