The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace.

The two distinguishing features of Franklin's stove were ( 1 ) a hollow baffle ( i. e., a metal panel that directed the flow of the fire's fumes ) and ( 2 ) a flue that acted as an inverted siphon.

Since the pollutants included metal vapour, the sweepings of the flue could also be recovered for resmelting.

This arrangement resulted in a greatly increased surface contact area of hot pipe with boiler water when compared to a single large flue.

* Flue Pipe Acoustics, a scholarly description of flue pipe physics

Today's central heating systems have made chimney placement less critical, and the use of non-structural gas vent pipe allows a flue gas conduit to be installed around obstructions and through walls.

* Diapason ( pipe organ ), a tonal grouping of the flue pipes of a pipe organ

See wind instrument and flue pipe.

This is an example of a typical pipe organ stoplist, showing both common stop names and conventional formatting ( flue pipes listed in black, reed pipes listed in red ):

* Vent or flue, a duct, pipe, or chimney for conveying exhaust gases from a furnace or water heater

According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack or propelling nozzle.

A flue pipe ( also referred to as a labial pipe ) is an organ pipe that produces sound through the vibration of air molecules, in the same manner as a recorder or a whistle.

Air under pressure ( referred to as wind ) is driven down a flue and against a sharp lip called a Labium, causing the column of air in the pipe to resonate at a frequency determined by the pipe length.

) Thus, there are no moving parts in a flue pipe.

The diameter of a flue pipe directly affects its tone.

A closed flue pipe with a uniform cross-section sounds an octave lower than a similar open pipe of the same length.

Flue gas is the gas exiting 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.

Quadrupling the width of an organ pipe aperture at a fixed blowing pressure resulted in somewhat less than a doubling of velocity at the flue exit.

Bourdon, bordun, or bordone normally denotes a stopped flute / flue type of pipe in an organ characterized by a very dark, heavy tone, strong in fundamental, with a quint transient but relatively little overtone development.

The heat for the house was initially obtained by running a flue from the nearby palm house but it was later equipped with its own boiler.

He then moved the chimney to the east side, running a Y-shaped split flue inside the walls up either side of one of the windows above.

These were connected by elements beginning at the saturated header, running through the flue tubes and back to the superheater header, and the whole assembly was vertically arranged for ease of maintenance.

The third method is by simply using an induced draught fan ( ID fan ) which removes flue gases from the furnace and forces the exhaust gas up the stack.

The breeching directly below it collects the flue gas and brings it up high into the atmosphere where it will not endanger personnel.

That higher pressure outside the chimney is the driving force that moves the required combustion air into the combustion zone and also moves the flue gas up and out of the chimney.

Using his back, elbows and knees, he would shimmy up the flue in the manner of a caterpillar and use the brush to dislodge loose soot, which would fall over him and down to the bottom, and a scraper to chip away the solid bits, as a smooth chimney was a safe chimney.

He and his workers changed fireplaces by inserting bricks into the hearth to make the side walls angled and added a choke to the chimney to increase the speed of air going up the flue.

The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.

Prominently marked ' chimney ' on Ordnance Survey maps, the flue ran over half a mile up the fellside to a stone chimney at about.

This " horizontal " chimney ( parallel to the ground, which actually rises steeply to the moors ) was used to carry poisonous flue gases from the Rookhope lead smelting works up onto the high moor.

SCR catalysts have a typical operational lifetime of about 16, 000-40, 000 hours in coal-fired power plants, depending on the flue gas composition, and up to 80, 000 hours in cleaner gas-fired power plants.

This kind of flue was large enough to allow men to climb up the inside and scrape off the condensed lead.

The route of the collapsed double flue up the moor is easy to follow.

The space inside a chimney is called a flue.

The combustion flue gases inside the chimneys or stacks are much hotter than the ambient outside air and therefore less dense than the ambient air.

Sea coal started to replace wood, and it deposited a layer of flammable creosote in the inside surface of the flue, and caked it with soot.

In modern chimney construction a corbel table is constructed on the inside of a flue in the form of a concrete ring beam supported by a range of corbels.

As they do not require a chimney and are " flueless ", bio ethanol fires are extremely useful for new build homes and apartments without a flue.

Even so, boys rarely climbed chimneys before the Great Fire of London, when building regulations were put in place and the design of chimneys was altered, The new chimneys were often angular and narrow, and the usual dimension of the flue in domestic properties was by.

As the single opening at the top of the new stack was only about wide, the flue needed regular maintenance.

A new, emerging flue gas desulfurization technology has been described by the IAEA.

The new stacks were required to accommodate cooler flue gas saturated with water vapor that resulted when wet SO < sub > 2 </ sub > scrubbers were added.
