The Adam mantels are in wood enriched with ornament, cast in molds, sometimes copied from the carved wood decoration of old times. [1] Mantels or fireplace mantels can be the focus of custom interior decoration. A mantel traditionally offers a unique opportunity for the architect/designer to create a personal statement unique to the room they ...
A fireplace insert [1] is a device that can be inserted into an existing masonry or prefabricated wood fireplace. Fireplace inserts can be fuelled by gas, wood, electricity, coal, or wood pallet. Most fireplace inserts are made from cast iron or steel. Fresh air enters through vents below the insert, where it then circulates around the main ...

[21] Mantel—Either the shelf above a fireplace or the structure to support masonry above a fireplace [23] Smoke shelf—A shelf below the smoke chamber and behind the damper.
Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection. A traditional fireplace can also draw hot air in from the room and expel it through the chimney, further lowering the efficiency. The design of the direct vent ...
The Rumford fireplace created a sensation in London when he introduced the idea of restricting the chimney opening to increase the updraft. [5] He and his workers changed fireplaces by inserting bricks into the hearth to make the side walls angled, and they added a choke to the chimney to create a circulation of air inside the chimney.
An early version of the gas mantle lamp, kerosene was vaporized by a secondary burner, which pressurized the kerosene tank that supplied the central draught. Like all gas mantle lamps, the only purpose of the burner is to hold the flame that heats the mantle, which is 4-5 times as bright as the wick itself.
Mantle convection is the very slow creep of Earth's solid silicate mantle as convection ... and the distance over which convection occurs—all of which give stresses ...
[21]: 238 The result is that the hoods are operating at the minimum exhaust volume whenever no one is working in front of them. [ 29 ] Since the typical fume hood in US climates uses 3.5 times as much energy as a home, [ 30 ] the reduction or minimization of exhaust volume is strategic in reducing facility energy costs as well as minimizing the ...
