Description
SZL Series Hot Water Boiler Specification
SZL water tube easy installation(assembled) boiler has 2 horizontal drums, and the
innovative horizontal cyclone-fired combustion chamber, which could effectively enhance
the thermal efficiency and reduce the flue gas emission concentration. The flue gas emission
concentration is lower than 100 mm/nm3, the flue gas blackness is lower than Ringelmann
level 1,which enables the boiler to be used in the first-class environment protected area.
The boiler installs one cast iron economizer at its back body, the fire-gate applies the
chamber-segregated ventilation structure, which is easy to adjust. The separate-layer coal
supply device could be chosen according to the customer requirement. Advantages of
such boiler are: strong power, high thermal efficiency, 110% override capability,
compactly designed, small floor area.
