What is boiler | Types of boiler | How does a steam boiler work

What is boiler? A boiler is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.

Reheaters - an overview | ScienceDirect Topics

Double-RH thermal power plants have nearly 450 m of pipework between the boiler and turbine, manufactured from high-cost materials, against 150 m of such pipework for a single-RH plant. Therefore, alternative boiler-turbine configurations could reduce the length of the pipework and thus dramatically reduce capital costs.
