The saturated steam thus formed is further superheated. After passing over the heating surfaces at various zones the flue gas is cooled and discharged to the atmosphere through a stack. The primary function of a steam generator is to generate steam under pressure, but modern steam generators are also required to do the following: i. Ensure
Steam's energy is converted into mechanical energy by forcing it through a steam turbine. The high pressure of the steam pushes on the many angled blades of the turbine, causing the shaft to rotate. This mechanical energy is converted to electricity by using the power form the rotating shaft to turn an electrical generator.
Dec 27, 2013 · Steam generator part 1 1. BOILER Prepared by: Mohammad Shoeb Siddiqui Sr. Shift Supervisor Saba Power Plant 2. Steam Generator (Boiler) Hello, I am trying to explain about Steam Generator (Boiler) in this session, due to length of said presentation, I am deciding to divide it in three parts. Part 1 cover the “Introduction & Types of Steam Generator” Part 2 cover about the “Parts of Steam
For more information, see: Steam. A steam generator is a device that uses a heat source to boil liquid water and convert it into its vapor phase, referred to as steam.The heat may be derived from the combustion of a fuel such as coal, petroleum fuel oil, natural gas, municipal waste or biomass, a nuclear fission reactor and other sources.
Oct 29, 2016 · A steam generator is basically a heat exchanger. A heat source warms a pool of liquid water to above boiling temperature. Steam vapor collects in the space at the top.
Jul 25, 2017 · The steam function won’t work well if there isn’t enough water to create the kind of steam pressure you want. Use a good ironing board designed to work with a steam generator iron. A wider surface area for ironing and a special tray for holding the steam generator iron base will make ironing easier.
A wide variety of steam generators (also simply called boilers) are in use today, and most of the larger ones are used to generate electricity. The most commonly seen types of steam generators include firetube, flextube, electrical, condensing, commercial and heat recovery steam units.
As water passes through the coil, the heat is transferred from the hot gases which causes the water to convert to steam. The generator design does not utilize a steam drum where the steam of a boiler has a disengagement area from the water in so the use of a steam/water separator to achieve 99.5% steam quality is required.
Jun 03, 2020 · Steam iron is used to remove wrinkles and creases of the clothes. There are different types of steam irons, such as handheld steam iron, water tank steam iron, and simple best steam iron. Steam iron is preferable than dry iron or any other electric iron.
Entire steam generators are often replaced in plant mid-life, which is a major undertaking. Most U.S. PWR plants have had steam generators replaced. History. The nuclear powered steam generator started as a power plant for the first nuclear submarine, the USS Nautilus.
