The liberalization of the European energy markets combined with the rapid spread of
unpredictable renewable energy sources have stressed the need of improving the traditional …

Abstract A CFD (Computational Fluid Dynamics) model of steam superheater in stationary
and non-stationary state was presented in the paper. The developed model allows for …

Coal-fired boiler tubes are generally exposed to high internal pressure and high
temperature of steam and flue gas. The common cause of any metallurgical failure of a …

Superheater model was used to analyzing the impact of ash deposits on the outer tube
surfaces and scales formed on the inner tube surfaces on the heat flow rate transferred from …

The failure analysis of a ruptured superheater tube after 20 years service in the oil-fueled
boiler, as the typical problems in power plants, was investigated. A thin-lipped rupture at …

This paper investigates the causes of failure in the tubes of a 12,000 kg/hr. dual fired steam
boiler used in a Food and Beverage manufacturing plant located in southwestern Nigeria …

The present study concentrated on the metallurgical, micro-and macroscopic observations,
hardness evaluation, as well as X-ray diffraction (XRD) and energy-dispersive spectroscopy …

The spread of wind turbines and photovoltaic modules for green electricity generation is
stressing the need of installing large-scale electricity energy storage. Among the in …

This paper highlights a methodology for failure investigation of superheater tubes made of
the material T-22 of a coal-based boiler. The process includes visual observation, the …

Increased temperature and decreased hardness values of the tube metal and development
of oxide scale on the inner surface of boiler tubes over prolonged period of time are typical …
