METHOD AND DEVICE FOR HIGH-TEMPERATURE COMBUSTION USING FUEL AND AQUEOUS SOLUTION OF ORGANIC COMPOUND

摘要

A method and a device are disclosed with which high-temperature combustion is attained using a fuel and an aqueous solution of an organic compound, e.g., an aqueous alcohol solution. In a combustion chamber, a fuel is sprayed and burned with a first burner to elevate the interior temperature of the combustion chamber (and/or a heat-resistant reflector disposed inside the combustion chamber) to a high temperature of 700ºC or above, and an aqueous solution of an organic compound (e.g., an alcohol-water mixture) is subsequently sprayed with a second burner into the high-temperature combustion gas obtained with the first burner, thereby causing microexplosion of water vapor and further elevating the interior temperature. Thus, high-temperature superheated steam containing a large amount of water vapor is yielded.
