METHOD AND DEVICE FOR GENERATING A HEATING MEDIUM

摘要

Provided are a method and device for generating a steam heating medium, the method involving generating, from a nozzle, Aqua-gas or low-temperature superheated steam that is a steam heating medium by operating an electrothermal-type generator or a steam-type generator. The method comprises the step of generating Aqua-gas by increasing a water supply amount in such a manner that an internal nozzle pressure takes on a constant value exceeding a saturated water vapor pressure of water at each internal nozzle pressure set temperature; or generating low-temperature superheated steam by reducing the water supply amount in such a manner that the internal nozzle pressure does not exceed the saturated water vapor pressure of water at each internal nozzle pressure set temperature, in a relational expression relating to a flow rate of water vapor sprayed from the nozzle, and given by Expression 1 or Expression 2, as prescribed in the present invention.
