Cooling metallized

The combustor is assembled of flanged, spool-shaped water-cooled metal components, each with its own water-cooling circuit and pressure shell. No ceramic linings are used. Gas pressure is contained by stainless steel outer shells and the internal surfaces subject to high heat fluxes are lined with low alloy water-cooled panels. 

Electrode Walls. Development of durable electrode wads, one of the most critical issues for MHD generators, has proceeded in two basic directions ceramic electrodes operating at very high surface temperatures (>2000 K) for use in channels operating with clean fuels such as natural gas, and cooled metal electrodes with surface temperatures in the range 500—800 K for channels operating with slag or ash-laden flows. 

Although ceramic electrodes have received much attention (101), they have not been successful in channels operating with slag-laden flows, because of excessive electrochemical corrosion caused by the slag. Only weU-cooled metallic elements have been used successfully in slagging environments. 

A fairly recent application of the water-cooled metal belt to solidification duty is shown in Fig. 11-54. The operation is termed pastilhz-...

The injector should also be cleaned by removing the liner and cleaning the cooled metal injector with methanol. Allow the injector to dry and insert a clean liner. 

Superconductors have the ability to levitate vehicles with embedded magnets. This picture shows an experimental zero-friction train in Japan, built to use helium-cooled metal superconductors. 

It is impossible to find inert containers owing to both the high mp of borides (> 2000°C) and their reactivity with refractory materials. The problem is solved by melting borides either in water-cooled boats or pedestals. Water-cooled, metal...

Cool Metal—by applying water directly onto the protected surface to prevent distortion or rupture from flame exposure or radiant heat. 

In an ice-cooled metal reactor was charged a 50 vol % solution of the alkene in liq HF and CIF gas was passed through the solution in equimolar quantity with respect to the substrate. The mixture was poured onto ice. The organic layer was separated, neutralized with anhyd NalICO, and evaporated to leave the product which was purified by distillation. 

PIG IRON. Product of blast-furnace reduction of iron oxide in the presence of limestone. About half the ore is converted to iron. Average analysis is 1% silicon, 0.03% sulfur, 0.27% phosphorus, 2.4% manganese, 4.6% carbon, balance iron, Pig iron is the basic raw material for steel and cast iron. In metal terminology a pig is a bar or ingot of cooled metal. 

Cutting oil oil used to lubricate and cool metal-cutting tools also called cutting fluid, cutting lubricant. 

But the Doctor s other arm was his own. His free hand shot into his pocket and closed around a cool, metallic crescent. Straining now, as Garudin latched on to the movement, the Doctor pulled out the half-...
