Conduct Tests Remotely to Discover Health With Switchees remote testing tool you can pre-emptively identify Maintenance teams have a reduced number of emergency callouts and spending on maintenance is regular with no large spikesGet a Quote
mills similar to those used in the gold mining industry produce finer ground coal as was well proven at Lethabo where the calorific of the coal is equivalent to that of a Provita biscuit This coal is the most inferior coal used by Eskom with an ash content of inGet a Quote
It is often difficult to determine detrimental conditions because the large number input and output parameters create a complex problem Such was the case in this study where a radiant superheater and internal desuperheater were retrofitted in an existing industrial water- at a South African sugar millGet a Quote
The insulating effect of a can cause tube metal overheating and subsequent failure Because they are usually porous deposits can also provide sites for boiler water concentration and consequently the potential for caustic attackGet a Quote
Because pits can penetrate deep into the metal can result in rapid failure of feedwater lines economizers boiler tubes and condensate lines Additionally iron oxide generated by the corrosion can produce iron deposits in the boiler mayGet a Quote
· These hot spots will have a significantly lower creep life than operating at expected metal temperatures and will cause unexpected and early life The temperature distribution is not random and a pattern can typically be found where only a handful of are at risk of failureGet a Quote
