The effectiveness of chemical methods depends primarily on a type of healing agent, number of carriers (capsules, tubes, vascular networks), degree of dispersion of carriers in concrete and their diameter. The carriers of healing agent should be made of materials which are non-reactive with concrete and healing agent.

Some interesting features of a modern power statio

2019-5-13·Today, we have been forced to use the same rail transporter for transformers with a rating of 390 MVA. This has been made possible by transformer designers who, by using improved materials and advanced techniques, have been able to produce transformers of greatly increased capacity, yet conforming to the rigid limitations of our rail system.


2018-11-22·These materials have been mostly freed by dissolving a fraction of the hemicellulose and side chain moieties broken-off from the hemicellulose, and include sugars, tannins, and small organic acids such as acetic acid. These materials also get washed out in the wash chamber 280, and in the water extrusion processes 290 and 300 along with the

Sloss Furnace Sloss-Sheffield Steel & Iron Compan

In addition to reducing the labor from forty or fifty men to five, the pig machine provided a cleaner, more uniform product than before. It was a decided advantage not to have sand adhere to the iron, and it was much easier to maintain chemical consistency if the iron were thoroughly mixed in a ladle car rather than running freely. from the furnace to the sand molds.

Distillation - Fair* - - Major Reference Works - Wile

Figure 1b shows how the simple batch distillation still is turned into a continuous distillation tower (or column), which in principle is a multiplicity of simple stills mounted on top of each other. In Figure 1b, there are three contact stages. Unlike the batch still in Figure 1a, the feed enters and products are drawn continuously in Figure 1b. . Figure 2 shows how this simple still evolves

Volume 3: Design and Analysis | ASME 2011 Pressur

Anti-seize materials exist to serve two functions, to help even out stud stresses/preloads during assembly, and most importantly, allow the components to be taken apart after they have been exposed to heat. This paper looks at how different anti-seize materials are affected after being exposed to enough heat to burn off the grease base.

A 1000 MWth boiler for chemical-looping combustio

More than 2000 h of solid-fuel CLC operation in a number of smaller pilot units clearly indicate that the concept works. A scale-up of the technology to 1000 MW th is investigated in terms of mass and heat balances, flows, solids inventories, boiler dimensions and the major differences between a full-scale Circulating Fluidized-Bed (CFB) boiler and a Chemical-Looping Combustion CFB (CLCCFB).
