A thermal power station is a power plant in which the prime mover 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 .
In thermal power plants, water droplets in high-velocity steam from nozzles erode turbine blades. According to the principle of operation, they are classified into Impact or Baffle type, Reverse current type, Centrifugal type.

A composite approach is needed to insure that the entire coating will function as protection - not just the surface of the coating. Not Just the Surface Sulfur induced corrosion on alloy 625 weld overlay and a Ni/Cr thermal sprayed composite coating. Compromises in the alloy's surface film require a constant source of oxygen to repair.

Thermal power plant or thermal power station is the place where we use the energy of heat to produce electric power, and it's the most convenient sources of electric power generation, as we burn fuels such as oil, coal or liquefied natural gas to produce high temperature, high-pressure steam then we use this steam to turn a steam turbine
Gas flowing through a typical power plant turbine can be as hot as 2300 degrees F, but some of the critical metals in the turbine can withstand temperatures only as hot as 1500 to 1700 degrees F. Therefore, air from the compressor might be used for cooling key turbine components, reducing ultimate thermal efficiency.
Abstract— In the present, studied "Energy Auditing of Thermal Power Plant: A Case Study" The Energy aspects tell us how we can increase the efficiency of a thermal power plant. In this work, I have studied various parameters like boiler, turbine, thermal insulation, cost benefit analysis etc. It is
For instance, if we raise the boiler efficiency from 85% to 90%, the resulting overall efficiency of the combined cycle power plant is raised to: OE = (33.33 x 98% + 66.67% x 90% x 37%) x 100% x
Vapor Power International. Vapor Power's six distinctive product lines provide steam generator, thermal fluid heater, hot water and superheated steam solutions, to meet every industry need and application.
