Ibrahim Dincer, Marc A. Rosen, in Exergy (Third Edition), 2021. 12.1 Introduction. Steam power plants are widely utilized throughout the world for electricity generation, and coal is often used to fuel these plants. Although the world's existing coal reserves are sufficient for about two centuries, the technology largely used today to produce electricity from coal causes significant negative ...
The Acoustic Steam Leak Detection (ASLD) system works on the principle of detecting the sound waves emanating from the steam leak, processing the same and then indicating the quantum of steam leak and the location. When a leak is detected by a change in the sound patterns, alarms are activated and the fault is localized.

The balance of plant of the centralised control room only remotely monitors but does not do any centralised monitoring and controlling. As the inter-industry competition intensifies, the balance of plant system of the power plant also needs to shift from having a single system to having BOP to exercise integrated and centralised control.
Modern thermal power plant 1. Introduction A steam power plant / thermal power plant is using steam as working fluid. A thermal power station is a power plant in which the prime mover is steam driven. Steam is produced in a boiler using coal as fuel and is used to drive the prime mover, namely the steam turbine. Water is heated, turns into steam & spins a steam turbine which …
