Flows through and touches the second porous material The air is effectively heated to a higher temperature without flow. Mixtures of exhaust gas and 1 8. The process of heating the air to a higher temperature before combustion by means of radiation and Thermal radiation is absorbed by the porus medium as described in point 1. 7. Relies on hot gas caused by The burning of a venturi burner (12) allows the hot gas to expand, flow through the porous material, radiate heat and then vent to the outside, while also relying on the venturi effect on the isthmus of the pipe. Venturi Induce the primary air (35) to pass through the porous material, absorbing heat radiation (17) to warm it up to a significantly higher temperature. Automatic without the use of a fan or air pump to help the burner.
