This study aims to develop a high-performance radiant heater which would be able to convert almost all energy released by combustion into thermal radiation. A compact radiant heater was produced, which was an application of the effective energy conversion method from flowing gas enthalpy to thermal radiation emitted from the porous medium of an appropriate optical thickness placed in a duct of high-temperature gas. It consists of a porous medium energy converter and a quartz window. It is also equipped with a convective heat exchanger between the burnt and unburnt gases. The thermal radiation emitted from the porous medium energy converter is taken out in the opposite direction to the burnt gas flow. The temperature profiles in the heater were examined and the energy balance of the heater has been elucidated. The results shows that 80 to 90% of the energy released by combustion is converted into thermal radiation.
