The oil burner nozzle is usually mounted in the front of the firebox, protected by a hood of firebrick, and aimed at the firebrick wall below the firebox door. Dampers control air flow to the oil fire. Schematic of a later steam locomotive firebox boiler, with firebox to the left and indicatively showing two superheater elements to the right.
The main components of a typical steam locomotive. Click or hover over numbers to see names. The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types.
The stack and the damper have been removed for clarity. In steam locomotive use, by far the most common form of superheater is the fire-tube type. That takes the saturated steam supplied in the dry pipe into a superheater header mounted against the tube sheet in the smokebox .
The South African Railways Class 14B 4-8-2 of 1915 was a steam locomotive. In 1915, the South African Railways placed fifteen Class 14B saturated steam locomotives with a 4-8-2 wheel arrangement in service. When they were subsequently converted to superheating, they were reclassified to Class 14.
In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders into the Chimney via a nozzle or 'blast pipe' this creates a vacuum in the Smokebox. The Lempor ejector is a development of similar multiple orifice/nozzle ejectors which create either a stronger vacuum or the same vacuum more efficiently ...
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.
The South African Railways Class 19D 4-8-2 of 1937 was a steam locomotive. Between 1937 and 1949, the South African Railways placed 235 Class 19D steam locomotives with a 4-8-2 Mountain type wheel arrangement in service. Between 1951 and 1955, 33 more were built for other operators like the Rhodesia and Angolan railways and the Nkana and Wankie ...
