Heating by radiation is widely used for materials possessing and a radiant heater in which electricity has been mainly used. Electricity is expensive and emits CO_2 when energy is converted to electricity from fossil fuel. In order to transfer the energy of fuel to radiation energy directly and efficiently, our group had developed a compact high efficiency radiation converter using a spiral heat exchanger to recover the energy from high-temperature exhaust gas. The combustion chamber equipped with a swirler to mix fuel gas and air, can achieve stabile combustion. The distribution of the surface temperature of radiant tube was measured by a radiation thermometer so called thermo viewer, then radiant energy emitted from the radiant tube was estimated. The efficiency of the spiral heat exchanger was measured from temperature of inlet air and exhaust gas. High effectiveness of the heat exchanger was achieved and heat loss by the exhaust gas was minimized. Consequently, a high efficient radiation converter was achieved to transfer the fuel energy to radiation energy.
