The dimensions of the blastpipe and chimney are critical to the steam-generating capacity of the locomotive and its fuel economy, since there is a natural trade-off between a high-velocity steam jet giving a strong draw on the fire, and back-pressure on the exhaust. Small changes to this "front end" design can have a dramatic impact.
The steam locomotive exhaust system consists of those parts of a steam locomotive which together discharge exhaust steam from the cylinders in order to increase the draught through the fire. It usually consists of the blastpipe (or first stage nozzle), smokebox , and chimney , although later designs also include second and third stage nozzles.
Pipe smoking is the practice of tasting (or, less commonly, inhaling) the smoke produced by burning a substance, most commonly tobacco or cannabis, in a pipe. It is the oldest traditional form of smoking .
The Frank Method is a method for packing tobacco into a smoking pipe initially developed by Achim Frank for use in pipe smoking competitions.. The Frank method involves compacting the tobacco from the sides without compressing the top.
Smoking a pipe involves more equipment and technique than smoking cigarettes or cigars. In addition to the pipe and a source of ignition like matches or a pipe lighter , pipe smokers typically use a pipe tool for packing, adjusting, and emptying tobacco from the bowl, along with a regular supply of pipe cleaners to maintain the pipe.
A smoking pipe is used to taste the smoke of a burning substance; most common is a tobacco pipe. Pipes are commonly made from briar , heather , corncob , meerschaum , clay , cherry , glass , porcelain , ebonite and acrylic .
The Blast Pipe (a) directs exhaust steam into the smokebox (b). The steam entrains the smoke from the firebox (c), creating more draft which helps speed the smoke out the chimney (d). The primacy of discovery of the effect of directing the exhaust steam up the chimney as a means of providing draft through the fire is the matter of some ...
Increasing the velocity of steam exhaust tended to both accelerate airflow through the firebox and lift the smoke higher above the top of the chimney. By the 1830s, steam exhaust was directed through a contracted nozzle called a blastpipe, so as to achieve the desired velocity through the chimney. Pressure drop through the blastpipe nozzle was ...
