Introduced in the late 19th century, steam turbines are largely used for generating electricity across many parts of the world. In addition to power generation, these mechanical devices are also used in various industrial applications and marine propulsion. According to a recent report, they are responsible for generating nearly 80% of the world’s electricity, employing fossil and nuclear fuels as well as from specific renewable sources. Considering the present situation, it can be derived their usage is all set to reach new heights in future.
A technology-led solution
The whole concept of steam turbines is that they procure heat produced from burning fossil fuels, from nuclear reactors and from various biomass and other renewable sources that eventually drive generators. Based on a preliminary 1884 design by British engineer Charles Parsons, steam turbines quickly became the major source of electricity power generation. Steam turbine generator technology has developed significantly over the years and the tractability of steam turbines allows them to be employed for a great variety of applications, operating in association with various energy sources and other systems to enhance their overall efficiency.
One solution for multiple applications
Do you know most of the electricity produced in the world nowadays is generated using steam turbines? From 50 kW to several hundreds of MWs, there are various power plants that rely on this technology to meet varied demands of electricity. Contrary to gas-based turbines, where heat results as a byproduct of power generation, these turbines produce electricity from steam, a derivative of heat.
Due to this property, there comes out the option of using a range of fuels including nuclear energy, fossil fuels, biomass and others. These may also encompass CHP (combined heat power) systems, in which steam is procured from the turbine and is employed for heating purpose or transformed into other types of thermal energy such as hot or chilled water as well as industrial elements such as chemical plants, refineries, or pulp and paper factories. In some cases, low-cost fuel options such as wood chips, residual refinery oils, and other byproduct fuels are used to run steam turbines, enhancing energy use and limiting the amount of waste product generation. As compared to other options, steam turbine repair companies find it much feasible to work on these machines due to their simple mechanical structure.
Power generation using natural energy
Apart from using fossil fuels for power generation, steam turbine is also used to generate clean power by harnessing the efficiency of renewable energies. For example, in many cases natural heat of the sun and the earth surface is transformed in geothermal power facilities and in concentrated solar power systems.
Steam turbine technology supports power generation using three most commonly employed CSP technologies- parabolic trough, solar power tower and linear Fresnel systems. In case of parabolic channel settings, a heat transfer fluid is heated using concentrated intensive sunlight and is driven using heat exchangers to generate steam. In the other power generation settings, concentrated sunlight is employed directly boil the water, generating steam which is served into steam turbines to produce electricity.
According to experts, these turbines are not only capable enough of generating required amount of electricity an easy way but tend to improve overall efficiency of mechanical process. For example, besides power generation capacity, repair and maintenance are also important. In order to maintain the turbine functional for longer periods of time, it is necessary to count on the most effective, steam turbine maintenance services that are really valuable.
There are many steam turbine manufacturing companies in India that provide full-fledged turbine solutions to power generation companies from repair to maintenance. These turbine manufacturers provide back-pressure and condensing steam turbines that work across a wide variety of pressure and flow applications. In addition, they also provide a wide assortment of integrated solutions such as erection & commissioning, spare parts, operations & maintenance and refurbishing, among others.
Though only big players are involved in this segment, it is still much needed to choose the right partner who can meet all your power generation needs in a cost effective and efficient manner. In addition, technology should always be on top seat when it comes to invest in steam power turbines for your facility. Make sure to check international standards with respect to turbines to generate the best value out of your investment.
