Hot oil heaters and thermal fluids: the complete guide | …

A boiler with a horizontal assembly allows it to be located in rooms that are relatively low in height and permits convenient and easy access to the burner and to the various parts of the equipment. By contrast, the greater needs for floor space with respect to a vertical boiler, can sometimes be a decisive element in the final decision.

High Temperature Corrosion in Boilers - Bright Hub …

23/9/2009 · High temperature corrosion in a boiler firing coal is mainly caused due to the presence of impurities like sulphur, alkali metals and chlorine. In fuel oil fired boilers, the main impurities are vanadium, sulphur, sodium, and chlorine. During combustion, these elements combine to form various types of vapors and condensed phases.
