Abstract
We have developed the successful technique to improve the temperature exchange efficiency at the heat exchange region by absorbing thermal radiation energy emitting from CO_2 1n the combustion exhaust gas. The electro-magnetic radiant materials as the absorption materials are applied at the inner surface of combustion chamber (Spectrum Heat Absorption Technique). .In order to check how robust our results are, the verification tests on the temperature exchange efficiency are carried out by employing the wick diffusion flames and fire tube and flue boilers. The fuels studied are kerosene, ethanoi, and methanol for wick diffusion flames and LNG for fire tube and flue boilers (capacity:6ton/h). From these results obtained from the verification test we may predict that the spectrum heat absorption technique is very useful and effective to achieve the high energy saving through the improvement of thermal efficiency on fossil fuel combustion.
