... are the main compounds. These results indicate that high temperature oxidation played a key role in the degradation of the components, which is consistent with exposure at high temperatures. Abstract The electric power plant technology for the utilization of heavy fuel oil rich in sulphur, vanadium...

...High temperature corrosion in boilers firing heavy fuel oil has long been a major problem ^{1 , 2} . Early studies on the subject were developed a few decades before ^{3 , 4} . Most of the experience in this field is associated with the utilization of the lighter residual fuels...

...Abstract The role of operational power changes on the corrosion of SA-213-TP-321H stainless steel tubes of a steam superheater was studied. The power unit where the tubes are installed is a 158MW fired with residual oil fuel and the plant is subjected to "peaking operation". The fuel oil consumed...
