Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited. Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008. [10]
A single experimental tank engine was constructed to burn oil in 1902, and 37 engines of four different classes were converted to burn oil between 1946 and 1950. Neither experiment resulted in the long-term use of oil as fuel for steam locomotives. A single pannier tank locomotive was also converted under British Rail in 1958.
Vessels typically contained several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. . The fire room got its name from the days when ships burned coal to heat steam to drive the steam engines or turbines; the room was where the stokers spent their days shoveling coal continuously onto the grates under the ...
Receives the hot gases that have passed from the firebox through the boiler tubes and, when the throttle/regulator is open, directs them and steam exhausting from the cylinders up the smokestack/chimney, sucking air through the firebed. The smokebox may contain a cinder guard to prevent hot cinders being expelled.
A shell or flued boiler is an early and relatively simple form of boiler used to make steam, usually for the purpose of driving a steam engine. The design marked a transitional stage in boiler development, between the early haystack boilers and the later multi-tube fire-tube boilers .
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
Where such a boiler may be heated either by the exhaust gases of the main propulsion plant, or else separately fired when in port (usually by oil rather than coal) it is referred to as a composite boiler. [4] The boiler is a cylindrical vertical water drum with a hemispherical domed top. This domed shape is strong enough not to require staying.
Improved design and maintenance almost totally eliminated the first type, but the second type is always possible if the driver and fireman do not maintain the water level in the boiler. Boiler barrels could explode if the internal pressure became too high. To prevent this, safety valves were installed to release the pressure at a set level.
