The tank is usually cylindrical for the most part—being the strongest practical shape for a pressurized container—and this cylindrical tank may be either horizontal or vertical. This type of boiler was used on virtually all steam locomotives in the horizontal "locomotive" form.

PROPULSION BOILERS (BOILER COMPONENTS

Why are drum type boilers installed in a way that the long axis of the boiler drum runs fore and aft, rather than athwartships? Top of the boiler, cylindrical in shape, but on some boilers the steam drum may be slightly flattened along its lower curved surface.

Steam Boilers and Stay Bolts - Farm Collect

On the other hand a flat boiler head is subjected to a high internal pressure and has a tendency to bulge as shown by the drawing. To prevent the plate from assuming the bulged shape and possibly exploding or cracking, stays or braces must be used to hold it. Stay bolts in a steam boiler

Vertical boiler with horizontal fire-tubes - Wikiped

2019-9-7 · 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. The boiler is a cylindrical vertical water drum with a hemispherical domed top. This domed shape is strong enough not to require staying.

why maintain ph 9 6 to10 5 boiler drum

It is cylindrical in shape and situated at the top of the boiler. In Super-critical units, water is directly converted into steam so drum is not required, but in case of subcritical boilers, the whole water quantity is not directly converted into steam. Why does boiler drum ph maintain from 9.5 to 10.2 .
