METHOD AND DEVICE FOR GENERATING HEATING MEDIUM

PROBLEM TO BE SOLVED: To develop an aqua gas generation system using a heat exchange method by electric heat and steam. SOLUTION: A method is for generating a steam heating medium (aqua gas or low-temperature zone superheated steam) from a nozzle by operating an electric heat type generater or a steam type generator. The method and a device for generating the steam heating medium generate the aqua gas by increasing a supplied water amount so that nozzle internal pressure exceeds the saturated steam pressure of water at respective nozzle internal pressure set temperatures to show a constant value, or generate the low-temperature zone superheated steam by decreasing the supplied water amount so that the nozzle internal pressure does not exceed the saturated steam pressure of water at the respective nozzle internal pressure set temperatures in a relational expression of a formula 1 or a formula 2 specified by this invention.
