Modeling and simulation of a natural circulation water

In the present work, the overall behavior of a steam boiler is investigated using RELAP5/MOD3.2 system code at three different operating loads. Main thermal–hydraulic parameters are analyzed at steady-states corresponding to 60%, and 110% of the boiler nominal load. RELAP5 system code is widely used in the design and safety analysis of nuclear reactor installations as well as for

The Implementation of a Steam Transformer System

2015-7-29 · A steam transformer may be described as a single effect evaporator that uses live or exhaust steam and delivers process vapour to the end user. It effectively de-couples the clean boiler steam/condensate circuit from the process vapour/condensate circuit. The Al Khaleej factory uses saturated steam at a pressure of about 140 kPa (a).

Theory of Steam Turbines - Thermodynamics

2021-2-27 · In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy.In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices. Unlike with reciprocating engines, for instance, compression, heating and expansion are continuous and

Evaporators - an overview | ScienceDirect Topics

An overall steam economy of 4–5, depending on the number of effects, is normally good for mill operation. If this stage is a bottleneck, lower steam economy is sacrificed for higher throughput. The initial steam introduced at the first effect comes from the boiler, and its condensate is returned to the boiler.
