<p><P>PROBLEM TO BE SOLVED: To provide a thermogenic agent mainly used in a heating apparatus for portable heating and cooking vessels, reaching a temperature in the heating apparatus to about 90°C to about 100°C in a short time without increasing the weight and the bulkiness of the agent and keeping a retention time required for lowering to 60°C for at least 20 min. <P>SOLUTION: The thermogenic agent is obtained by compounding 10 g powdery aluminum with 10 g powdery quick lime. The thermogenic agent in an amount of 20 g is brought into contact with 40 g water and the powdery quick lime is reacted with water to generate reaction heat and produce calcium hydroxide and the calcium hydroxide is reacted with powdery aluminum to generate reaction heat and about 3886 cal/g is utilized as a sum of both reaction heat. <P>COPYRIGHT: (C)2004,JPO</p> |
