Sharing the Flue - Fine Homebuilding

2012-11-8 · Condensation of gases can lead to flue corrosion, taking us back to spillage of combustion gases and chance of fire. In order to avoid these conditions, the diameter, height, and lateral length of a flue must be sized for the appliance that it's venting.

flue gas | English to Portuguese | Engineering (general)

Flue gas is gas that exits to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, it refers to the combustion exhaust gas produced at power plants.

This produces high pressure, hot flue gases that can be used to drive a gas turbine as well as using the reactor to raise steam for a steam turbine. Fluidized beds have the advantage of being able to capture sulphur within the bed, with the addition of limestone, thereby reducing sulphur dioxide emissions from the boiler.

Draft Regulators - Barometric Dampers: A Guide to

The draft as sensed at the barometric damper is too weak (maybe a wind is blowing down the chimney flue because we left off our chimney cap): in this case the draft inside the flue, at the breech and thus at the draft regulator is less negative, maybe -0.01" w.c. than we wanted - we're having trouble sending those flue gases up the chimney.

Flues and tubes - Trains Magazine - Trains News Wire

Flues are normally any boiler tube larger than 4 inches in diameter. Tubes are smaller than 4 inches in diameter. Tubes and flues both serve the same function: they carry the gases of combustion through the boiler and provide the heat transfer surface which transfers the heat of combustion to the water in the boiler.
