The DZH series adopts a horizontal three-pass water-fire tube structure, with a rated evaporation capacity of 3 tons per hour and a rated working pressure of 1.25 MPa. Equipped with manual feeding and manual slag removal systems, the boiler features simple operation and low maintenance requirements, perfectly matching the operational conditions of small and medium-sized Bangladeshi factories with limited automatic operation teams. Its widened and deepened furnace chamber together with secondary air supply structure ensures full combustion of wood logs, delivering a steady thermal efficiency above 82%. Threaded smoke tubes enhance heat exchange and lower exhaust temperature for outstanding
energy-saving performance. Full safety configurations including safety valves, high-low water level interlocks and pressure gauges are installed. Every unit undergoes hydraulic pressure tests, non-destructive testing and complete factory acceptance tests (FAT), fully complying with Bangladesh’s industrial equipment safety access standards.
