Surface condenser - Wikipedia

A surface condenser is a commonly used term for a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure.Where cooling water is in short supply, an air-cooled condenser is often used.

1. CLASSIFICATION OF INSTRUMENTS IN POWER PLANT

In general clasification of instruments in power plant are divided as mechanical instruments which measures parameter like- pressure,flow,level,speed,temp,viscosity,humidity,moisture etc and electrical instruments which measures parameters like- voltage,current,power,energy etc.

Thermal power station - Wikipedia

A thermal power station is a power station in which heat energy is converted to electric power.In most of the places in the world the turbine is steam-driven.Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
