A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Boiler Efficiency | How to balance steam loads efficiently
Oct 16, 2020 · Technological improvements have led to improved efficiency of natural gas generators since the mid-1980s, when combined-cycle plants began replacing older, less efficient steam turbines. For steam turbines, boilers combust fuel to generate steam that drives a turbine …
292 Chapter 14 Stack—an opening at the top of the boiler that is used to remove flue gas, p. 297. Steam drum—the top drum of a boiler where all of the generated steam is collected before entering the distribution system, p. 293. Steam trap—a device used to remove condensate or liquid from steam systems, p. 294. Superheated steam—steam that has been heated to a very high temperature so
If the heat output is less than that required by the user, it is Gas Turbine Generator Electricity Steam Ch-07.qxd 2/23/2005 11:24 AM Page 158. A gas turbine or diesel engine producing electrical or mechanical power followed by a heat recovery boiler to create steam to drive a
Steam Generator Vs. Boiler | Manufacturing.net
the heat to generate steam in a waste heat boiler, which then drives a steam turbine. Steam turbines are one of the oldest and most versatile prime mover technologies. Heat recovery boiler/steam turbine systems operate thermodynamically as a Rankine Cycle, as shown in Figure 2. In the steam Rankine cycle, the working fluid—
There is also the issue of steam saturation. Steam should have a dryness of 0.95 (steam by weight) and contain less than 3.5% (gases by volume) of non-condensable gases. Electric Steam Generator. An electric autoclave steam generator (or boiler) utilizes electric heating elements to heat water and generate steam.
