SZL Water Tube Biomass Boiler

SZL biomass boiler is a water tube structure boiler, longitudinally double drum boiler, combustione device is chain grate or reciprocating grate(step grate).

SZL series water tube boiler can fueled by wood, biomass, coal, palm kernel shells, coconuts shell, rice husks, sawdust, bagasse.

Has SZL-A & SZL-D types, especially SZL-D type is our company patented feature product. High technology, environmental and energy saving.

SZL Core Technology

★ Whirlwind burning chamber structure

★ Indenpend wind chamber structure and secondary wind burning

★ Fron-rear water-cooled arch design

★ Large furnace capacity, wid biomass fuel adaptablity

★ Membrane water wall construction

★ Double 12cm Layer Aluminum silicate insultion

★ 5 stage water level and pressure protection, automatic interlock device

BOILER Advantages Of

① Offset furnace design, 15% bigger furnace combustion, the heated area increases along.

② Membrane type furnace wall, not easy to collapse, good airtightness, no deformation, no dust falling

③ Best wind adjust design, segmented air supply (preheating zone, drying zone, main combustion zone, coke zone, ash slag zone) can freely adjust the air volume

④ Secondary cyclone burnout chamber, reduce fuel cost, save running cost, improve boiler thermal efficiency

⑤ Built-in dust removal device inside boiler, effectively solve the problem of coking, low original dust discharge concentration

⑥ Equipped energy-saving device like economizer/preheater/cyclon/wet scrubber, environmental protection and energy conservation

⑦ Recommended suitable grate materials, and chain grate, reciprocating grate, or water cooling vibrating grate, according the fuel features.
