Exercise 1. Read and memorize using a dictionary:

prime mover, steam driven, recycle, Rankine cycle, facilities, district heating, waste incineration, waste heat, overall efficiency, power plant, fossil-fuel power plants, co-generation, conventional power plant, commercial electric utility power stations, alternating current (AC), steam-driven power plants, naval ship, shipboard power plants, couple, ship's propellers, gearbox, nuclear marine propulsion, co-generation plants, nearby buildings, reciprocating steam engines

Exercise 2. Answer the questions:

1) What is a thermal power station?

2) What do some thermal power plants also deliver heat energy for?

3) How arepower plants burning coal, fuel oil, or natural gas often called?

4) What kind of electrical generators do electric power plants typically use?

Exercise 3. Match the left part with the right:

1. Water is heated, turns into steam and	a) due to the different fuel sources.
2. The greatest variation in the design of thermal power stations is	b) spins a steam turbine which drives an electrical generator.
3 Natural gas is frequently combusted	c) are usually constructed on a large scale and designed for continuous operation.
4. Commercial electric utility power stations	d) in gas turbines as well as boilers.

Exercise 4. Open brackets choosing the right words:

Electric power plants typically (use/utilize) three-phase electrical generators to produce (alternating current (AC)/ direct current (DC)) electric power at a frequency of 50 Hz or 60 Hz. Large companies or institutions may have their own power plants (to supply/ to provide) heating or electricity to their facilities, especially if steam is (created/ originated) anyway for other purposes.
