Industrial boilers are generally divided into steam boilers and hot water boilers. Although both types are evaluated based on heat output, the way their capacity is expressed reflects different application logic.

Steam boiler capacity is usually expressed in tons per hour (t/h), indicating the continuous steam output under specific pressure and temperature, while hot water boiler capacity is measured in kilowatts (kW) or megawatts (MW) .

Case Study: Steam Boiler Selection in Tire Manufacturing

PT Pakan Sehat Unggul (PT PSU), a leading poultry feed and livestock products company in Indonesia, requires a stable and continuous steam supply for sterilization, cooking, and mixing processes. The company also aimed to utilize locally available biomass resources, such as palm shells, to reduce energy costs and achieve greener production. Driven by growing production demand,  PT PSU ultimately selected ZOZEN SZL series biomass steam boilers.

To meet PT PSU’s specific needs, Wuxi ZOZEN Boiler provided a custom-designed SZL10-1.25-SS biomass steam boiler, optimized for palm shell combustion. The boiler features a horizontal double-drum, longitudinal layout with an advanced chain grate system and high-efficiency combustion design. The grate structure ensures uniform fuel distribution and complete combustion, minimizing slag formation and blockage. Densely arranged water-cooled walls and extensive furnace radiation surfaces enable a thermal efficiency exceeding 86%, while the low carbon content in ash indicates efficient fuel utilization.

With this installation, PT PSU now enjoys a reliable, high-efficiency steam supply that meets continuous feed production demands, reduces energy costs, and supports environmentally friendly operations. This project demonstrates how tailoring biomass boiler design to specific fuel characteristics and production requirements ensures optimal performance and operational reliability.
