High Temperature Heating System (HTHS)
Abstract
Natural gas has potential to become an energy alternative to electrical resistance heating for process temperatures above 1800F in furnaces where controlled process atmospheres are required. This program is intended to develop and integrate into a system, a radiant tube gas fired heating element, burner and energy recovery device. A thermal analysis is performed and shows that the heat flux of radiant tubes may be increased by application of a high combustion intensity burner and a heat transfer enhancement mechanism to increase the rate of heat transfer from the combustion products to the heating element. A radiant burner is developed which is capable of burning ten (10) times as much fuel per unit of volume as conventional radiant tube burners. The burner and radiant tube combination has demonstrated a 200 to 300 percent increase in heat flux compared to conventional systems.
