Superheater Metal Temperature Measurement
Measurement and Control, 1970 With the insistence of the Electricity Boards that Boiler manufacturers be responsible for installation of metal temperature measuring equipment, it is necessary that the companies should be in a position to implement this requirement. The report examines the performance of selected thermocouple attachments under simulated service conditions.

Numerical simulation of superheated steam flow in dual-tubing wells
Journal of Petroleum Exploration and Production Technology, 2017 In this paper, a novel model is presented to estimate the thermophysical properties of superheated steam (SHS) in dual-tubing wells (DTW). Firstly, a mathematical model comprised of the mass conservation equation, momentum balance equation and energy ...

Lifetime estimation of superheater header
Procedia Structural Integrity, 2016 AbstractThe safe operation of thermal power plants (TPPs) is largely determined by the reliability of main components of steam systems of power units, to which belong the headers of boiler superheaters.The aim of the study is to estimate the residual lifetime of superheater header starting from the initial defect size and up to the maximum allowable ...

Experimental study of heat transfer characteristics among the two-phase expansion process
Mechanical Engineering JournalDifferent from a gas expander, there is a phase change from liquid to vapor called the flash inside the two-phase expander. But, same with the gas expander, only the vapor phase expands and pushes the rotation of the expander to output power in the two ...
