Modeling, Simulation, and Control of Steam Generation

Apr 10, 2019 · This chapter describes a modeling methodology to provide the main characteristics of a simulation tool to analyze the steady state, transient operation, and control of steam generation processes, such as heat recovery steam generators (HRSG). The methodology includes a modular strategy that considers individual heat exchangers such as: economizers, evaporators, superheaters, …

US5368775A - Corrosion control composition and method for

A corrosion control composition and method for boiler/condensate steam systems is provided. Corrosion is controlled by the addition to the feedwater of a relatively high molecular weight amine. The high molecular weight amine is formulated so that at the conditions of temperature and pressure in the boiler/condensate steam system, partial degradation into more volatile amines occurs.

The Essentials of Continuous Evaporation | AIChE

In theory, the evaporation of 1 kg of water requires slightly more than 1 kg of steam, since the latent heat of vaporization decreases as pressure increases (3). As the steam's latent heat is transferred to the feed, some of the heat raises the initial feed temperature to the boiling point and the remaining latent heat evaporates water.

Steam explosion - Wikipedia

A steam boiler has an interface of steam and water in the steam drum, which is where the water is finally evaporating due to the heat input, usually oil-fired burners. When a water tube fails due to any of a variety of reasons, it causes the water in the boiler to expand out of the opening into the furnace area that is only a few psi above
