Introduction

Yuanda Boiler - 69 Years of Industrial Boiler Manufacturing, a Globally Certified Boiler Factory

Founded in 1956, Yuanda Boiler is a Class A industrial boiler and pressure vessel manufacturer with 69 years of experience. We offer reliable biomass boiler from 0.1ton to 40ton, with ASME, CE, EAC, and DOSH certifications.

Main Wood Biomass Boiler Series:

DZH / DZL Series: Water and fire tube mixed boilers
SZL / SZW Series: Water-tube biomass boilers
WNS Series: Biomass burner fire tube boiler
LSG Series: Vertical wood biomass boiler with a compact design


Wood Fired Water&Fire Tube Boiler

DZL and DZH boilers is an innovative water-fire tube structure equipped with spirally corrugated flue pipes and airfoil-shaped flue ducts. Through "α"-shaped flue gas recirculation and secondary air distribution technology, combined with a strategic heating surface layout, they achieve fuel savings and efficient operation. Therefore, it is known as the revolution of industrial boilers.

The DZH boiler is a manually operated boiler with moving grate, requiring manual fuel feeding and slag removal. So it particularly suitable for firewood, tree log, blocks, waste fabric, solid waste and other big size fuel.

Wood Fired Water Tube Boiler

Water tube wood biomass boilers, also known as horizontal double-drum boilers, include both D-type packaged water tube boiler and A-type assembled water tube boilers. They feature a full-membrane water-cooled wall structure, customizable combustion mechanisms, independent cyclone burnout chambers, front and rear water-cooled arches, secondary air system, built-in ash cleaning, and a multi-stage dust removal system.

Customizable combustion device: chain/traveling grates, reciprocating/stepped grates, and fluidized beds available. Adaptable to various wood & biomass fuels.

Wood Fired Fire Tube Boiler

WNS series biomass burner boiler is a horizontal three pass fire tube boiler, also know as combined biomass boiler. The fuel is burned in the front burner, suitable for wood chips, wood pellet, wood sawdust. And it can change to gas or oil burner once  you do not want use biomass as fuel.

Wood Fired Vertical Boiler

Small scale industrial boiler, vertical design. Small footprint, low investment cost. Simple structure, easy to use and install
