The world is facing the challenge of providing abundant and affordable electricity to meet the
need of a growing global population, while lowering and controlling CO 2 emissions. Both of …

A comprehensive numerical study of the combustion optimization of a 660-MW tangentially
fired boiler under the constraint of steam tube overheating is presented. To obtain the …

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 …

This paper investigates the heat transfer of superheater tubes in one 600 MW boiler
combining the 3-D CFD simulation and the 1-D analytical model. To confirm the validity of …

Creep is a slow and continuous plastic deformation of materials over extended periods
under a constant load and high temperature [1]. Traditionally creep has been associated …

The efficiency of the coal-fired boilers can be enhanced through increasing the operating
steam pressure and temperature. Though, higher steam pressure and temperature may …

This paper establishes and examines the constitutive model of the modified theta-projection
concept for predicting the creep-rupture behaviour of a 2.25 Cr-1Mo ferritic steel alloy foil at …

The failure of a superheater tube in a coal-fired power plant, designed to resist creep
damage at high temperatures and pressures, was investigated after it ruptured following …

Based on the thermal deviation theory and local energy and mass balance of the
superheater tube, a new method of calculating tube wall temperature is proposed. The wall …

The spallation of steam-side oxide scale on boiler tubes can seriously influence the safety of
power plants. In this work, the failure behavior of oxide scale formed on T91 alloy …
