Radiant Heat Absorption by Water-Walls of Steam-Boiler Furnaces (2nd. Report) : Finned-Tube Walls

Full Analysis of Low Finned Tube Heat Exchangers

In this paper, first the governing parameters characterizing low-finned tubes are reviewed. Second, the more important of the available performance correlations are compared with the available experimental data. The most reliable one can be employed to develop a pressure drop relationship, which has already been used in an algorithm for exchanger sizing. Also a means for the identification of a...

1 . WALLS OF WATER Tsunamis

Tsunamis I got outside my hotel, and saw that the ocean was now level with our island. To my horror, a wall of water— boiling, frothing, angry as hell—was bearing straight down at us, and a strange mist that looked like thick fog blocked out the sun. I stopped breathing. .. . —Dave Lowe, eyewitness to the 26 December 2004 tsunami on the South Ari Atoll in the Maldives W e relate Christmas to ha...

Numerical Studies on the Performance of Finned-Tube Heat Exchanger

Finned-tube heat exchangers are predominantly used in space conditioning systems, as well as other applications requiring heat exchange between two fluids. The design of finned-tube heat exchangers requires the selection of over a dozen design parameters by the designer such as tube pitch, tube diameter, tube thickness, etc... Finned-tube heat exchangers are common devices; however, their perfo...

Efficient model-based leak detection in boiler steam-water systems

A model-based least-squares algorithm with a time-varying forgetting factor is developed for leak detection in boiler steam-water systems. The algorithm has been tested using real industrial data from Syncrude Canada, and has proven to be effective in detection of boiler tube or steam leaks; proper implementation of the algorithm would lead to early leak warning, which is important in maintaini...
