Steam engine - Wikiped. A steam engine is a heat engine that performs mechanical work using steam as its working fluid.In simple terms, the steam engine uses the expansion principle of chemistry, where heat applied to water evaporates the water into steam, and the force generated pushes a piston back and forth inside a cylinder.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Types of Boilers Nuclear Steam Generating System Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core.

The Basics of Steam Generation - 4 A simple boiler In order to describe the principles of a steam boiler, consider a very simple case, where the boiler simply is a container, partially filled with water (Figure 1). Combustion of fuel produce heat, which is transferred to the container and makes the water evaporate. The vapor or steam
A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
