Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Steam locomotive - Wikipedia

The intense heat causes water in the boiler to turn into steam, which is piped into the cylinders (24). Valves (25) cause the steam to oscillate the pistons (23) back and forth. The piston rod (22), connecting rod (21) and coupling rod (19) transmit the movement to bearings on the wheels, converting the oscillation to rotation, which moves the locomotive as shown in this animation

Types of Boiler Explained: Combi, System & Conventional

A conventional boiler is often found in older homes, but a lot of modern homeowners choose to replace them with a system or combi boiler as they deliver higher water pressure. However, some older properties may not have pipework which can cope with higher water pressure and so need to keep using a conventional boiler system.
