Efficiency is a critical aspect when it comes to steam boilers, measuring their ability to convert fuel into usable heat energy. Numerous factors influence the efficiency of steam boilers, including boiler design and type, fuel quality and type, combustion process, heat recovery, boiler operation and maintenance, as well as boiler load and runtime. ZOZEN, a modern enterprise producing 2,000 boilers annually, offers a wide range of the most efficient steam boilers to meet the diverse needs of various industries.

Why ZOZEN’s Boilers Are the Most Efficient Steam Boilers:
ZOZEN’s steam boilers boast a remarkable efficiency rating of up to 98%. Let’s analyze their efficiency from four different aspects: boiler design and type, combustion process, heat recovery, boiler operation and maintenance.

  • Boiler Design and Type:
    ZOZEN offers steam boilers fueled by oil, gas, biomass, and coal, including circulating fluidized bed boilers. These boilers are designed with consideration for different fuel characteristics, ensuring high efficiency, energy savings, and stable operation.
  • Combustion Process:
    ZOZEN’s steam boilers employ advanced low-NOx burners. Whether it’s a two-pass or three-pass design, ZOZEN’s unique approach ensures thorough fuel combustion, resulting in enhanced system thermal efficiency.
  • Heat Recovery:
    ZOZEN’s steam boilers can be equipped with economizers and condensers, effectively utilizing the waste heat in flue gas. By raising the feedwater temperature and reducing exhaust gas temperature, ZOZEN boilers achieve the status of the most efficient steam boilers.
  • Boiler Operation and Maintenance:
    ZOZEN’s steam boilers are designed for stable operation, and following the operation and maintenance manual ensures the boilers perform optimally, reducing energy losses and system failures.

ZOZEN’s Most Efficient Steam Boiler Products:

Oil and Gas Steam Boilers:

  • ZOZEN offers three series of oil and gas-fired steam boilers: the WNS series condensing horizontal internal combustion boiler, the SZS series condensing double-drum vertical arrangement boiler, and the ZZ series medium-temperature and medium-pressure oil/gas steam boiler.
  • All three series feature large furnace designs, achieving thermal efficiencies of up to 98%, making them the most efficient steam boilers.
  • They accommodate a wide range of fuels, including natural gas, coke oven gas, biogas, as well as diesel, heavy oil, light oil, and residual oil.
  • The thermal capacity ranges from a minimum of 1t/h to a maximum of 130t/h, catering to various scales and requirements of different enterprises.

Biomass/Coal Steam Boilers:

  • ZOZEN offers three series of biomass/coal-fired steam boilers: the DZL series single-drum vertical arrangement chain grate boiler, the SZL series double-drum vertical arrangement chain grate boiler, and the SHL series bulk chain grate boiler.
  • All three series feature densely arranged water-cooled walls, providing a large radiation area. The SHL series achieves an efficiency of up to 88% for biomass combustion, making it the biomass-fired most efficient steam boiler. The SHL series also achieves an efficiency of ≥82% for coal combustion, making it the coal-fired most efficient steam boiler.
  • All series boast high mechanization levels with advanced control systems. Automated fuel supply, ash removal, and slag discharge operations make them easy to operate.
  • The boilers are adaptable to various fuels, including biomass particles, wood chips, palm shells, straw, as well as bituminous coal, anthracite coal, and lean coal.
  • The thermal capacity ranges from a minimum of 2t/h to a maximum of 75t/h.

Customer Case Study:
ZOZEN collaborated with a Vietnam-based new materials industry, providing two 10-ton SZL series coal-fired steam boilers.
