Damper Functions In Boiler Economiser

Composite steam boiler

Starting, stopping and modulating the burner normally controls the steam pressure in the composite boiler. In the old days a huge damper was used to by-pass the composite boiler when the steam demand was less than the steam quantity produced by the diesel engines exhaust gases. Nowadays a pressure governed control valve dumps excess steam into

The automatic flue damper traps heat in the furnace, boiler, or water heater. It holds heat in and around the heat exchanger instead of allowing it to rise up the flue. The control voltage from the appliance powers the automatic vent damper. The automatic vent damper has a little motor that powers it to the closed position. It leaves all the heat trapped inside the furnace, boiler, or hot water heater.

Economiser: Flue gases coming out of the boiler carry lot of heat. Function of economiser is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is placed in the passage of flue gases in between the exit from the boiler and the entry to the chimney.
