Abstract
A vapor generator is provided for producing vapor such as steam to be used for heavy oil recovery and the like. The vapor generator includes an octagonal cross-section furnace, which has evaporator surface arranged to allow for heating of said fluid to final evaporation in a relatively low heat flux portion of the generator to lessen the likelihood of scale formation on heat transfer elements of the vapor generator.
