Apr 01, 2011 · If the heat loss is greater than the energy output of the fire the fire will extinguish. Both modes, flaming and non flaming surface modes, can occur singly, or in combination. Flammable liquids and gases only burn in the flaming mode. Wood, straw, and coal are examples where both modes may exist simultaneously.

In one study he made a model of the mouth of the river Mersey, and he also worked on the determination of the mechanical equivalent of heat in multi-stage steam turbines. Using dye, he determined that the flow of a liquid will be turbulent unless it has high viscosity, low density, and an open surface.

Steel Glossary | Glossary of Terms | Platts

There are normally three electrodes, but only one with direct current furnaces. Much effort has been directed at minimising the time from scrap charging to steel pouring (tap-to-tap time). It is now standard practice to transfer steel to a separate furnace for alloying modifications (secondary metallurgy) to free-up the EAF for the next charge.

Steam Piping Systems - an overview | ScienceDirect Topics

Steam lines should ideally be arranged to fall in the direction of flow, at not less than 100 mm per 10 m of pipe (1:100).This slope will ensure that gravity (and the flow of steam), will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed (see Fig. 15.4).Any steam lines rising in the direction of flow should slope at not less than

Causes and Prevention of Corrosion on Welded Joints

Dec 17, 2015 · A welded joint can have a low resistance to corrosion due to the varying chemical composition, residual stress and metallurgical structure of the weld zone. Corrosion of weld joints can be avoided by the careful selection of materials to be welded, the filler metal, welding techniques and finishing. However, even after closely matching the metals and using the best techniques, weld …

Glycol Dehydration Process - an overview | ScienceDirect

The glycol dehydration process is an example of a process that provides absorption dehydration, and in the process, a liquid desiccant provides the means to absorb water from the gas stream. Ethylene glycol (HOCH 2 CH 2 OH) was, initially, the principal chemical agent in this process, has a very strong affinity for water and when the glycol is in contact with a stream of water-wet natural gas
