2019-5-26 · Steam is water in the gas phase, which is formed when water boils or evaporates.Steam is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as this water vapour condenses.At lower pressures, such as in the upper atmosphere or at the top of high mountains, water boils at a lower temperature than the nominal 100 °C (212 °F) at standard
2019-5-23 · The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam-electric power plants is
2015-7-13 · Chubu Electric has jointly developed a high-temperature superheated steam generation system with Japan Fine Ceramics Center and Daido Corporation. One unique feature of this system is its capacity for producing clean superheated steam at the high temperature of 600°C using an inductance heating system with heaters made from carbon.
2017-3-9 · Abstract—The aim of this research is to investigate the effect of ambient air temperature on the steam generation. A parametric study was performed based on exergy analysis to study the impact of ambient air temperature on second law of efficiency, irreversibility and adiabatic flame temperature of steam generation.
2003-10-30 · The Basics of Steam Generation - 4 A simple boiler In order to describe the principles of a steam boiler, consider a very simple case, where the boiler simply is a container, partially filled with water (Figure 1). Combustion of fuel produce heat, which is transferred to the container and makes the water evaporate. The vapor or steam
2013-2-12 · 1 HEAT TRANSFER SALT FOR HIGH TEMPERATURE STEAM GENERATION E. G. Bohlmann ABSTRACT AND SUMMARY A literature review and canvass of vendors reveals no experience and sparse, short term data bearing on the possible use of heat transfer salt (HTS - 40% NaN02, 7% NaN03, 53% KNOJ) at temperatures > 1000"F, Stability data found indicate that
Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of
For a given pressure, steam heated above the saturation temperature is called superheated steam, whereas water cooled below the saturation temperature is called subcooled water.If the boiling water is a closed system, then after converting all the water to steam, new heat energy coming into the system is used for increasing steam temperature i.e. superheating the saturated steam.
