More heat energy is contained within high temperature steam so its potential to do work is greater. The higher the pressure, the higher the temperature. It can be generated at high pressures to give high steam temperatures. The steam contains a large quantity of stored energy which will eventually be transferred to the process or the space to be heated. Depending on the pressure in the boiler, the water will evaporate at a certain temperature to form steam. When water is heated in a boiler, it begins to absorb energy. Steam can hold five or six times as much potential energy as an equivalent mass of water. In its gaseous form, it is a safe and efficient energy carrier. It is non-hazardous to health and environmentally sound. Steam is efficient and economic to generate Its use is popular throughout industry for a broad range of tasks from mechanical power production to space heating and process applications. Therefore as steam moves around a plant it can equally be considered to be the transport and provision of energy.įor many reasons, steam is one of the most widely used commodities for conveying heat energy. Steam provides a means of transporting controllable amounts of energy from a central, automated boiler house, where it can be efficiently and economically generated, to the point of use. Without it, our food, textile, chemical, medical, power, heating and transport industries could not exist or perform as they do. Steam today is an integral and essential part of modern technology. Steam has come a long way from its traditional associations with locomotives and the Industrial Revolution. It is useful to introduce the topic of steam by considering its many uses and benefits, before entering an overview of the steam plant or any technical explanations.
