A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [1]
Alternators made in 1909 by Ganz Works in the power generating hall of a Russian hydroelectric station (photograph by Prokudin-Gorsky, 1911). [1]An alternator (or synchronous generator) is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. [2]

The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.
By 1923 the plant at Harrogate comprised boilers delivering a total of 50,000 lb/h (6.3 kg/s) of steam to: [9] 1 × 300 kW turbo-alternator generating alternating current (AC) 1 × 1,000 kW turbo-alternator generating AC; 1 × 1,200 kW turbo-alternator generating AC; 1 × 1,250 kW turbo-alternator generating AC
The thermal power plant of Vouvry, also known as the Chavalon Plant, is a former power station located in the municipality of Vouvry, in the canton of Valais, Switzerland. Until its closure in 1999, the plant utilized heavy fuel oil, combusted to heat a steam generator. The vaporized water then drove a turbine, which powered an alternator.
Thermal power station ; Primary fuel ... 3 × 45 MW English Electric turbo-alternators generating at 10.5 kV, The plant installed in 1932–37 and 1950–54 ...
The steam produced in the boilers travelled at great pressure (38 kg/cm 2) to the turbo-alternator sets, which transformed the steam's thermal energy into mechanical energy through the turbine, which in turn transformed it into electric energy upon exiting the alternator.
