Steam engines of this kind propelled the Industrial Revolution in Great Britain and the world. The Watt steam engine design was an invention of James Watt that became synonymous with steam engines during the Industrial Revolution, and it was many years before significantly new designs began to replace the basic Watt design.
In one configuration the valve is lifted onto its seat by steam pressure and falls away under gravity when steam is shut off. This allows air to be drawn freely through it. Alternatively, the valve rests on its seat under gravity and is lifted by inward air flow, which can give rise to a characteristic rattle when a locomotive is coasting.
The sudden dispersion and projection of the water in the boiler against the bounding surfaces of the boiler is the great cause of the violence of the results: the dispersion, being caused by the momentary generation of steam throughout the mass of the water, and in its efforts to escape, it carries the water before it, and the combined momentum ...
Bent connecting rod after Hydrolock Same connecting rod, turned 90°. Hydrolock (a shorthand notation for hydrostatic lock or hydraulic lock) is an abnormal condition of any device which is designed to compress a gas by mechanically restraining it; most commonly the reciprocating internal combustion engine, the case this article refers to unless otherwise noted.
The shafts were turned by two oscillating steam engines, the largest ever built at the time. Each engine had a cylinder that was 100 inches (2.5 m) in diameter, and a piston that had a stroke of 12 feet (3.7 m). Eight boilers produced steam for the engines. The ship's machinery was built by the Novelty Iron Works of New York. [10]

It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.
