Abstract: Linear Fresnel collectors offer great potential for producing solar heat for industrial processes, both on a small and large scale. Thermal oil, pressurized water, or steam are used as heat transfer fluid in most applications, due to their suitable thermal properties. A heat exchanger is required for thermal power delivery to the user unless the heat transfer fluid is directly used as a medium in the industrial process. For those industrial applications using hot air as a process fluid, direct air heating inside linear Fresnel collectors can be an interesting solution aiming at simplification, cost reduction, and environmental and safety benefits.
