Introduction
According to different operation method, Yuanda wood boilers can be divided into two types: manual type wood boiler and automatic wood boiler.
Passed ASME CE ISO DOSH EAC certification. Can produce saturated steam, superheated steam and hot water for factory production.
It adopts water-fire tube structure, spirally corrugated fire tubes, wing-shape flue, new furnace arch with upside down "α"flue gas flow, secondary air distribution design, reasonable heating surface layout, and low operating cost.
DZH boiler using a moving grate, needs manual loading and deslagging, and is more suitable for firewood, wood blocks, logs, jute and solid waste.
It adoptes longitudinally double drum layout, water-cooled wall membrane structure, independent whirlwind cyclone burnout chamber, large furnace capacity, sufficient output, steam generation shortly, fast start, equipped with secondary air intake system, built-in dust cleaning, complete fuel buring and high thermal efficiency.
Automtic biomass boiler using chain grate or reciprocating grate, mechanized loading and deslagging, and is more suitable for wood pellet/briquette fuel, rice husk, coal, wood waste, wood chips, sawdust, bagasse, EFB, palm kernel shells, palm fiber, coconuts shell, wine lees, corn cobs...
