DZL Series Tri-drum Horizontal Type Firewood Steam Boiler Introduction

The DZL series tri-drum horizontal type firewood steam boiler is a third-generation water tube boiler. It is independently developed by ZOZEN Boiler and has independent intellectual property rights. The boiler adopts a modular structure, consisting of two large components, the upper and lower parts. The front part of the boiler body is surrounded by water-cooled walls, connected to the upper drum and connected to the header at the lower part, forming the combustion chamber to absorb the radiant heat of the furnace. In the rear part, between the upper and lower drums, there are convection tube bundles. After the fuel is burned in the furnace, the high-temperature flue gas flushes the heating surfaces of the convection tube bundles laterally, then enters the economizer, and finally enters the dust collector before being discharged through the chimney.

DZL Series Tri-drum Horizontal Type Firewood Steam Boiler Advantages

Wide fuel adaptability: Suitable for biomass pellets, rice husks, wood chips, corn cobs, sawdust, and more.

Complete fuel combustion: The design of ZOZEN’s chain grate and independent air chamber ensures thorough fuel combustion.

High thermal efficiency: The furnace adopts densely arranged water-cooled wall tube structure, providing a large radiation surface area, resulting in a thermal efficiency exceeding 87.5%.

Convenient operation and maintenance: Advanced control system enables high automation in fuel supply, ash removal, and slag discharge operations.
