Introduction
Most popular boiler is DZ single-drum biomass boiler and SZ double-drum biomass boiler. Both boiler using moving grate like chain grate or reciprocating grate. With advantages of mechanized automatic feeding, strong fuel adaptability, steady running, low emmision, and easy maintenance.
"DZ series" Biomass Boiler
DZ biomass boiler meaning single drum boiler, use water tube & fire tube structure, lower water quality requirements.
"DZL boiler" use chain grate, suitable pellet/woodchips/husk/shells; "DZH boiler" use traveling grate, suitbable logs/firewood/block/waste etc.Features:
1. It adopts horizontal packaged design(The furnace and chain 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.
"SZ series"Biomass Boiler
SZ biomass boiler meaning double drum boiler, use water tube membrane wall structure. High water quality requirements.
"SZL boiler" use chain grate, suitable pellet/woodchips/husk/shells; "SZW boiler" use reciprocating grate, suitable high humidity fuel like woodchips or residue/bagasse/sawdust/palm waste.Features:
1. 1-6ton adopts horizontal packaged design. 6-50ton 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. Adopt 3-step wet back structure, arched tube plate, to strengthen the efficiency of the boiler and prevent the tube plate from cracking.
2. The flue gases from two wings on the side reduce the smoke temperature, reduce the heat load of the bottom of the boiler and prevent bulging.
3. Secondary air ventilation system in the boiler, increases combustion efficiency and saves fuel costs.
4. Built-in steam separator, ensures high steam quality with humidity less than 1%
5. Anti-dry heating system, five-stage water level control, four-stage pressure protection
6. Built-in rotary soot blower and inspection door
7. The new large furnace design with dust separation chamber makes the boiler high efficiency and reduces the original dust.
Vertical coal biomass wood fired boiler. Easy to install, hand feeding boiler, less mechnical failure.
