Biomass/Bagasse /Coco Nut Fired Double Drums Steam Boiler

Description

SZL Series Steam Boiler Specification
SZL water tube easy installation(assembled) boiler has 2 vertical steam 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.

Q: What is a fire tube steam boiler?

A fire tube steam boiler is a boiler where the combustion gases from the burner are channeled through tubes that are surrounded by the fluid to be heated. The boiler body is the pressure vessel and contains the fluid. In most cases, this fluid is water that will circulate for heating purposes or become steam for use in processing.
Each set of tubes through which the combustion gas passes, before making a turn, is considered a “step”. Consequently, a three-step boiler will have three sets of pipes with the outlet located at the rear of the boiler.
