damper in steam boiler

Oil-Fired Boilers and Furnaces | Department of Energy

A vent damper prevents chimney losses by closing off a boiler's vent when the boiler isn't firing. Steam boilers benefit from vent dampers more than hot-water boilers, and bigger boilers benefit more than smaller ones. Vent dampers, however, may not be cost-effective with properly sized, newer furnace models.

The misunderstood barometric damper | 2013-02-13 | PM Engineer

One of the most misunderstood components inside a boiler room is the barometric damper, which is used to control the draft inside a boiler. It is installed on boilers that use a Category I vent. To understand how the barometric damper operates, we need to understand what draft is. We all know when air is heated, it will rise. When hot air from the boiler rises up the stack, it must be replaced
