In 2012, Valve announced Steam for Schools, a free function-limited version of the Steam client for schools. [145] It was part of Valve's initiative to support gamification of learning. It was released alongside free versions of Portal 2 and a standalone program called "Puzzle Maker" that allowed teachers and students to create and manipulate ...
Herreshoff steam generator in a Peruvian torpedo boat of 1879. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873. [1]

Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame. Steam generator (boiler), an oil- or gas-fired boiler, based on a low-water content monotube coil. Steam generator (nuclear power), a heat exchanger in a pressurized water nuclear ...
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 (7–2,000 kPa or 1–290 psi ) but, at pressures above this, it is more usual to speak of a ...
A generator or other such device can be placed on the shaft, and the energy that was in the steam can now be stored and used. The steam leaves the turbine as a saturated vapor (or liquid-vapor mix depending on application) at a lower temperature and pressure than it entered with and is sent to the condenser to be cooled.

The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz). The rotating parts of a turbo generator are subjected to high mechanical stresses because of the high operation speed.
A steam–electric power station is a power station in which the electric generator is steam-driven: water is heated, evaporates, and spins a steam turbine which drives an electric generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam–electric power plants is due ...
