The blastpipe is part of the exhaust system of a steam locomotive that discharges exhaust steam from the cylinders into the smokebox beneath the chimney...

order to increase the draught through the fire. It usually consists of the blastpipe (or first stage nozzle), smokebox, and chimney, although later designs...

road vehicles; and laid claim—still discussed and disputed today—to the blastpipe, a key component in the success of steam locomotives, engines, and other...

through the blastpipe, which is located within the smokebox. The steam is ejected through the chimney, again drawing the fire. The blastpipe is what produces...

as the 'Kylala spreader' involved the insertion of four nozzles in the blastpipe of steam locomotives. The system was originally devised to reduce spark-throwing...

where the conventional single opening is duplicated, together with the blastpipe beneath it. Although the internal openings form two circles, the outside...

usually acknowledged as the inventor of this concept. From 1830 onwards the blastpipe was employed by the Stephensons for their updated Rocket and all subsequent...

formal development as the injector, in the form of the arrangement of the blastpipe and chimney in the locomotive smokebox. The sketch on the right shows...

smokebox because in normal running the exhaust steam is sent through the blastpipe to draw the fire and eject the combustion products from the chimney...

the smokebox also permitted shorter steampipes and exhaust pipes to the blastpipe, giving better efficiency. Northumbrians were the last, and only, production...

achieve the desired velocity through the chimney. Pressure drop through the blastpipe nozzle was subtracted from the boiler pressure available to the steam...

strange rolling gait due to its vertical cylinders and the draft from the blastpipe was, in Hackworth's trademark style, very strong, so most of the coke...

hollow ring mounted either in the base of the chimney or on top of the blastpipe. Holes are drilled in the top of the blower ring, and when steam is...

fire. Credit for the invention of the blastpipe is disputed, though Stephenson used it as early as 1814. The blastpipe worked well on the multi-tube boiler...

steam from the cylinders similarly went through articulated ducts to the blastpipe at the rear of the tender, while articulated pipes connected the preheater...

reheater, in the upper part of the boiler flue, immediately before the blastpipe nozzle. This heated the exhaust steam to avoid it condensing into a...

steam is that it is no longer available to draw the fire, by use of the blastpipe. The draught must thus be generated instead by a steam-driven fan. Where...

air brake system made use of the following: A valve in the base of the blastpipe isolated the cylinders from the smokebox to prevent the ingress of hot...

brought the chimney in line with the cylinders and avoided a "set" in the blastpipe. The cylinders were arranged outside the plate frames. Like the Class...

smoke and flames from entering the cab through the firebox door – when the blastpipe is insufficiently effective, for example when a locomotive is stationary...
