SZL series biomass-fired hot water boiler

SZL series biomass-fired hot water boiler is package or shop-assembled water pipe boiler with double steam drum and chain grate stoker structure. 4-6 tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. The former part of boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace; there are dense convection tube bundle between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.

Product thermal capacity: 2.8-29 MW

Working pressure: 1.0-1.25 MPA

Available fuel: Biomass molding granules, wood chip, corn cob, saw dust

Our boiler products are applied in these enterprises.
