Basic of steam generation
Superheated steam has important advantages on certain applications, for example, when used in power stations to drive turbines for efficient use on heating applications however, the steam must be desuperheated this tutorial considers basic desuperheating theory and calculations. Electricity generation from steam turbines examples and diagrams of various types of steam turbines and ancillary equipment.
