Blastpipe
noun ·Rare ·Advanced level
Definitions
- 1 A pipe forming part of the exhaust system of a steam locomotive that discharges exhaust steam from the cylinders up into the smokebox beneath the chimney in order to increase the draught through the firebox; this speeds up the release of smoke through the chimney.
"[W]ith this arrangement the cylinders are cast separately from the saddle, and bolted to the frames on each side with a fabricated stiffener between the frames. This stiffener is carried up to form the saddle for the smokebox, and within it is fitted the exhaust pipes from the cylinders to the blast pipe."
