Introduction
Yuanda has "DZL/DZH" series water-fire tube wood boiler and "SZL/SZW" water tube wood biomass boiler. Can produce saturated steam, superheated steam and hot water for factory production.
Passed ASME CE ISO DOSH EAC certification, reliable high quality.
The wood/biomass boilers mainly includes the boiler boiler proper, fuel feeding system, combustion system(grate stoker), economizer, deaerator, feed water tank, ash handling system, emission control systems and PLC control system.
Both boilers use a horizontal water-fire mixing tube structure, lower water quality requirements.
Differences: DZL boiler using chain grate, mechanized loading and deslagging, and is more suitable for pellet/briquette fuel; DZH boiler using a moving grate, manual loading and deslagging, and is more suitable for firewood, wood blocks, logs, and wood waste.
Boiler Features:
1. It adopts horizontal packaged design(The boiler body and grate are packaged before delivery), which have less installation.
2. Spirally corrugated fire tubes, improves thermal efficiency, reduces flue gas temperature.
3. Wing-shape flue, allows smoke to enter the front smoke box smoothly, prevents tube sheet damage.
4. Hot water boilers adopts the unique backwater injection technology.
SZL/SZW both boiler adopts horizontal doube drum water tube membrane wall structure.
Differences: SZL boiler using chain grate, mechanized loading and deslagging, and is more suitable for wood pellet/briquette fuel; SZW boiler using reciprocating grate, mechanized loading and deslagging, and is more suitable for high himidity wood, wood chips, wood waste, sawdust, bagasse and so on.
Boiler Features:
1. 1-8ton adopts horizontal packaged design. 8-50ton usually delivered in bulk(The furnace and chain grate will assembled at user site), which requires more installation work.
2. Double drum A/D type layout, larger furnace apacity & heating surface.
3. Whirlwind burning chamber structure.
4. Front-rear water-cooled arch design.
5. Independent wind chamber.
1. Adopts 3-pass wet back sturcture, arched tube plate, spiral corrugated fire tubes, to strengthen boiler efficiency, prevent tube plate cracking
2. Two-Wing flue gas at side, reduce smoke temperature, reduce heat load of boiler bottom and prevent bulge.
3. Secondary air ventilation system in boiler, increase burning efficiency and save fuel cost
4. Built-in steam separator, ensure high steam quality with wetness below 1%
5. Anti-dry heating system, five stages water level check, four stages pressure protection
6. Built-in rotary sootblower and inspection door
7. New large furnace design with dust separation chamber, make boiler high efficiency, reduce the original dust
