Heat-Recovery Steam Generators: Understand the Basics

Heat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to …

Steam Generator | Definition & Characteristics | nuclear-power.com

high pressure steam produced by a boiler or heat recovery steam generator (HRSG). Unlike gas turbines or microturbines, steam turbines do not directly consume fuel. Rather, the fuel driving the process is the fired boiler or plant equipment that produces heat for

(PDF) Power Plant Lecture Notes - CHAPTER-3 STEAM GENERATOR

Steam generators are very rapid acting (produce steam within seconds). Superheated steam often leads to a reduction in the number of boilers, a reduction in the feed water usage, reduction in boiler load, improvement in the process timing, a reduction in the reagents, and …

A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler.[1] The narrow-tube construction, without any large-diameter drums or

Steam generator (boiler) - Wikipedia

LP Turbine – Low-pressure Steam Turbine Most of nuclear power plants operates a single-shaft turbine-generator that consists of one multi-stage HP turbine and three parallel multi-stage LP turbines, a main generator and an exciter. Each LP Turbine (low-pressure turbine) is usually double-flow reaction turbine with about 5-8 stages (with shrouded blades and with free-standing blades of last 3

If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple
