production of electricity from thermal energy click to hear : production of electricity from thermal energy

The heat that is given off by burning combustible fuels in the thermal power plant converts water into steam; the steam turns a turbo-alternator unit to produce electricity.

condenser click to hear : condenser

Circuit that cools the steam from the turbine and condenses it into water, which is reintroduced into the steam generator.

transmission to consumers click to hear : transmission to consumers

Electricity is carried to areas of consumption over low-voltage distribution lines.

voltage decrease click to hear : voltage decrease

The transformer reduces the voltage in order to increase the strength of the current; this allows a greater number of consumers to be served.

high-tension electricity transmission click to hear : high-tension electricity transmission

Using high-voltage lines to transmit electricity over long distances reduces the strength of the current and, as a result, energy losses.

voltage increase click to hear : voltage increase

At the outlet end of the power plant, the transformer increases the voltage; this reduces energy losses during transmission over long distances.

stack click to hear : stack

Pipe through which gases produced by burning coal are discharged; these gases are first partially cleaned to reduce pollution.

steam generator click to hear : steam generator

Device that uses the heat produced from burning coal to convert water into steam; the steam powers the turbo-alternator unit.

pulverizer click to hear : pulverizer

Device that pulverizes coal into a very fine powder so that it burns more easily in the steam generator.

coal-fired thermal power plant click to hear : coal-fired thermal power plant

Plant that produces electricity from thermal energy by burning coal.

crusher click to hear : crusher

Device that pulverizes the coal carried by the conveyor belt into relatively fine fragments.

coal storage yard click to hear : coal storage yard

Area where the coal extracted from a mine is stored to ensure a continuous supply to the thermal power plant.

belt loader click to hear : belt loader

Movable materials-handling device that is fitted with an inclined conveyor belt; it is used mainly to raise loads.

conveyor click to hear : conveyor

Materials-handling device that consists of a conveyor belt (sturdy belt on rollers) that carries coal to the crusher.

turbo-alternator unit click to hear : turbo-alternator unit

Device with a turbine that transmits the water’s mechanical energy to the alternator’s rotor to make it turn to produce electricity.

cooling tower click to hear : cooling tower

Device that cools the heated water in the condenser through contact with the air; a small amount of water evaporates and the rest is reinjected into the condenser.
