blast pipe

Here steam was removed at the blast pipe and led away along the top of the boiler.

It was regulated by a throttle valve on the blast pipe.

Just forward of the blast pipe, another chute was installed to clear cinders from the firebox.

When not working in tunnels, the steam was directed to the blast pipe and up the chimney in the usual way.

The blast pipe also increased the draught to the fire by concentrating exhaust steam at the base of the chimney.

This may take the form of a cylindrical mesh running from the top of the blast pipe to the bottom of the chimney.

It was the first A4 to be fitted with a Kylchap double blast pipe from new.

In 1943, with changes to draughting - blast pipe alterations and ashpan air openings were made.

Rocket has 25 copper fire-tubes that carry the hot exhaust gas from the firebox, through the wet boiler to the blast pipe and chimney.

The exhaust steam was led to the blast pipe via an articulated exhaust pipe fitted with stuffing boxes.

Someone had long ago ripped out the checkerwork, disconnected the blast pipes, and hacked out a crude door about a foot above ground level.

Archaeological specimens found at the site include stove walls used for iron reduction, blast pipe fragments, pottery shards, and slag heaps.

It was also necessary to devise new methods of connecting the blast pipes to the tuyeres, as leather could not longer be used for making the connection.

In 1940 Bulleid fitted one member of the class with a Lemaître blast pipe in an attempt to improve their efficiency.

The pistons and valves on the earliest locomotives were lubricated by the enginemen dropping a lump of tallow down the blast pipe.

From small grimy windows the top-gas extractors and blast pipes of the smelter were visible, crawling over its outer shell like vast slow worms.

The low position of the blast pipe in the larger smokebox at the front of the boiler is the least visible feature of the Einheitslokomotiven.

The existing blastpipe in a locomotive is replaced by several, small, fan-shaped, diverging blast pipes, from which the diffuser gets its flat, long, drawn-out shape.

Forced draught is provided in the locomotive boiler by injecting exhausted steam back into the exhaust via a blast pipe in the smokebox.

Among its innovations is said to be the blast pipe which directs exhaust steam into the chimney in such a way as to draw the fire, and seven more were built by 1832.

When the locomotive is stationary or in a restricted space "live" steam from the boiler is directed through an annular ring surrounding the blast pipe to produce the same effect.

As it turns out, Physicist Andi Petculescu and acoustics Professor Tim Leighton have already done just about everything short of actually blasting pipe organs into space.

Brunel and his assistant Daniel Gooch carried out their own experiments on the same locomotive and found that the only problem was that the blast pipe was too small.

Some of the examples that survived the longest were those fitted with mechanical stokers and Kylpor blast pipes or Giesl ejectors to improve their performance and reduce smoke.
