Centrifugal fans of SRT-HG series (Radial Straight- Hot Gases), have been especially designed for hot combustion gas transfer at low static pressure and up to 250°C.
Construction type: F3
Typical applications of centrifugal fans of SRT-HG series : natural draft increase in boilers , furnaces or incinerators stack of any type.
External impeller attached on motor shaft, prevents motor overheating via continuous air cooling. Geometry of SR (Radial Straight) fan impeller, ensures all particles conveyed by combustion gas to pass safely through the fan, and rejected into the stack.
Advantages of centrifugal fans of SRT-HG series:
- Max boiler combustion efficiency with adjustable gas draft applied by SRT fan.
- Low boiler-furnace service needs, due to complete solids and ash removal with SRT fan.
- No need for high stack installation to create gas draft.
Structure of centrifugal fans of SRT-HG series : Casing made of St 37 mild steel. Main and cooling impeller made of AISI 304 or 316 stainless steel. 3 or 1 phase electrical motor, coupling type B3.
