These brick-wall-constructed boilers, sometimes referred to as brick-faced boilers, were the first in the evolution of boiler design, but they were limited in size and capacity. As the size of the boiler increased, so too did the furnace heat input, the boiler rating (pressure), and steam temperature.

Function. To control the flow of steam from the boiler to the main steam pipe. To shut off the steam completely when required. Location: This valve is usually mounted over the boiler drum, in the steam pipe leading to-the steam turbine/engine, and between the steam, pipes to stop or regulate the flow of steam.

Energy. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Electric steam boilers use resistance-or immersion-type heating elements. Nuclear fission is also used as a heat source for generating steam, either directly (BWR) or, in most cases, in specialised heat exchangers called "steam …
