PURPOSE:To contrive to increase the infrared rays radiating quantity in low temperature region by a method wherein an active carbon is mixed with a volcanic rock, in generating method of large amount of infrared rays due to the heating of the volcanic rock. CONSTITUTION:A heat source 2 composed of a gas burner is arranged on a portable stove 1, a volcanic rock 3 consist of a rapidly cooled phase of magma and an active carbon 4 of about 5% is placed on the upper side of the gas burner 2. The active carbon 4 absorbes a heat radiation generated from the heat source 2 even at low temperature of 70 deg.C, then generates large amount of infrared rays coupled with the effect of radiation heat due to the synergiastic action with the volcanic rock 3 even under low temperature condition. |
