... oxidizing/reducing alternating conditions can become a very serious materials issue. Ash released from coal during combustion can cause significant problems to the behavior of the boiler components. During combustion, significant amounts of ash are carried by the flue gas stream and cause fly-ash...

..., eventually, asset management. Often, anything that can be safely done to keep a process unit on stream for long periods of time will be of great benefit. A large proportion of corrosion problems are actually caused by start-up or shutdowns. For example, when equipment is opened to the atmosphere for...

... 2 and 7 titanium as corrosion-resistant linings. In North America, so-called “acid rain” legislation requires utilities to clean the sulfur dioxide from their gaseous effluents. This is a very corrosive environment, particularly in closed-loop (recycled stream) systems, where chlorides concentrate...

.... The designer should play a significant role in reliability management. The communication chain, or the reliability loop, from the designer, to the manufacturer, then to the user, and back to the designer is a key factor ( Ref 29 , 37 ). When a risk is well documented, it should be possible to...

... around the pearlite. In both specimens, Widmanstätten side plates of ferrite grew into the prior austenite grains, but to a greater extent at the higher cooling rate. A point-count analysis showed that the steel in Fig. 4(a) had a pearlite volume fraction of 73%, whereas the specimen shown in Fig. 4(b...
