Power plant engineering is a division of power engineering, and is defined as “the engineering and technology required for the production of central station electric power.” The field is focused on the generation of power for industries and communities, not for household power production. The field is an interdisciplinary field, using the theoretical base of both mechanical and electrical engineering. The engineering aspect of power plant management has evolved with technology and has become progressively more complicated. The introduction of nuclear technology and the progression of other existing technologies have allowed power to be created in more ways and on a larger scale than was previously possible. The assignment of different types of engineers to the design, construction, and operation of a new power plant is dependent on the type of system being built such as whether it is a nuclear power plant, hydroelectric plant, or solar plant. Energy conversion is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (e.g. lifting an object) or provides heat. In addition to being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed. Energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, in order to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home’s air to raise its temperature. These questions will give you basic idea for Examinations Preparation and/or interview on Power Plant Engineering and Energy ConversionPlease Note: These questions are for practice and understanding level of knowledge only. It is not necessary that these questions may or may not appear for examinations and/or interview questions.
