Abstract
Abstract A boiler for a heat sensitive working fluid in which there are three systems, first, a stream of hot combustion gas system, second, a heat transfer fluid system and lastly, a heat sensitive working fluid system. The heat transfer fluid is at the interface between the hot combustion gas and the working fluid so as to prevent the formation of hot spots.
