advantages of water tube biomass boiler

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.
