High-temperature corrosion problems in steam

2019-8-23 · Abstract. There are essentially three distinct high temperature corrosion problems in fossil fuel fired steam boilers. These are: (1) corrosion of the superheaters and reheaters due to the deposition of fuel impurities, principally alkali metal sulfates in the case of coal-fired boilers and vanadium pentoxide in the case of oil-fired units.

A review of the oxidation behaviour of structural

2018-6-5 · Abstract The focus of this review is the state of knowledge of the oxidation behaviour in steam of alloys with potential for use as pressure parts in steam boilers. The rate of oxide growth on steam-touched surfaces and the characteristics of that oxide are of increasing interest as the quest for improvements in cycle efficiency leads to progressively higher operating temperatures and pressures.

Energy-Water Efﬁciency and U.S. Industrial Steam

Steam system energy efﬁciency not only makes sense from an environmental perspective, but also from an economic perspec-tive. As of 2006, U.S. manufacturers spent $21 billion on exter-nally purchased boiler fuels. The actual price tag of industrial steam is likely much higher; nearly one-half of U.S. boiler

An integrated method using MACBETH and EDAS

According to the results of the integrated method final ranking of steam boiler alternatives is obtained as A 1 > A 4 > A 3 > A 5 > A 2. As a result, the most appropriate steam boiler for the dyehouse is found as A 1 alternative. So it is advised to the dyehouse of the textile company to select the A 1 steam boiler.

Flow Stability of Heat Recovery Steam Generators

This paper presents the results of theoretical flow stability analyses of two different types of natural circulation heat recovery steam generators (HRSG)—a two-drum steam generator—and a HRSG with a horizontal tube bank.
