WebJan 31, 2024 · The furnace burns fossil fuels, hot gas heats the metal and the hot metal heats the air around it. Depending on the efficiency of the furnace in question, it would have one or two heat exchangers. The primary heat exchanger is the one closest to the burner in the furnace. As such, it absorbs the most heat and suffers the most stress. WebThermal management volume is further decreased when using Thermosiphons as the 3D volume is more isothermal and efficient. Also, when using a remote condenser unit as a heat exchanger, the number of tubes needed between the evaporator and condenser is a fraction of the number used for a similar heat pipe solution and can operate over longer distances. WebThe operation is very similar to that of a calandria where the liquid is boiled inside vertical tubes by applying heat to the outside of the tubes. The produced solvent vapor presses the liquid against the walls of the tubes forming a thin film which moves upwards with the vapor. irs disallowed expenses
