Author – Daniel G. Teleoaca – Marine Chief Engineer Understanding the Scavenging Air System The turbocharger uses the exhaust gas from the engine to compress new air and charge the engine with a positive pressure higher than ambient conditions. Exhaust gas temperature convection and compression raises the temperature of the air and this cannot be…
Asphaltene, carbon residues and sediments Asphaltenes are complex suspended solids in fuel that have high melting points and high carbon/hydrogen ratios. The proportion of asphaltenes in a fuel appears to increase as secondary refinery processes are more widely used. They have poor combustion properties and burn very slowly. If these formations precipitate, they can have…
Into the following posts I will explain about fuel oil properties and their effects from operational point of view. I will not write and show any mathematical formulas as these formulas can be found in dedicated manuals and anyone who is interested in depth theoretical knowledge can search for the same. The properties described in these posts are…
