Power plant engineering is a branch of engineering that is concerned with the design, construction and operation of large, thermodynamic machines that convert heat into mechanical work. The main purpose of a power plant engineer is to ensure that the end product is safe and efficient. Power plant engineering is an important engineering discipline, as the process of designing, constructing and operating a power plant is complex, and the consequences of the project can have significant impact on a nation’s economy. Power plant engineers need to be familiar with a wide variety of topics, including the process of converting heat into mechanical energy, the combustion of fossil fuels, and the management of hydroelectric generators.
