<p>A heat-resistant fuel activation substance is affixed to a combustion device such as a boiler in an adequate manner, that is, the substance is affixed in an adequate position over an adequate area, whereby the effect of activating combustion is rapidly, stably, and inexpensively produced. A heat-resistant fuel activation substance having a spectral emmisivity of 0.85 or higher at electromagnetic wavelengths in the range of 3-20 µm is affixed to a combustion device so that the heat-resistant fuel activation substance is disposed in a position which is located outside or inside the combustion chamber at the back of the flame-generating portion of the burner and rises to at most 300ºC in temperature and that the substance occupies at least 50% of the area of the projected part of the combustion cone.</p> |
