Supply
Mechanical auxiliaries
The equipment around the boiler: fans, ducts, dampers, tanks and hoppers, made or supplied, then installed and aligned on site.

Working principle
How it works
The working process in four steps.
Air goes in
The FD fan pushes combustion air into the furnace.
Gas is pulled out
The ID fan draws flue gas through to the stack.
Dampers set the flow
Dampers and ducts keep draught under control.
Alignment protects the train
Fan, coupling and motor are aligned to cut vibration.
