Title:
STEAM GENERATION DEVICE AND STEAM GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/176077
Kind Code:
A1
Abstract:
This steam generation device comprises a heat exchanger, a compressor, and a control unit, wherein: the heat exchanger has a heat source medium flow path, water supply piping that supplies water, and an electric heater; the heat source medium flow path has a configuration for heating the water; the compressor has a configuration for compressing low-pressure steam generated from the water in the heat exchanger to produce high-pressure steam; the control unit adjusts the output of the compressor and the electric heater; and the control unit determines whether heating by the electric heater is necessary. The foregoing makes it possible to stably supply high-pressure steam even if there is a fluctuation in the heat exchange amount from a heat source, in a steam generation device which generates high-pressure steam without using a refrigerant and in which the heat source is warm drainage or the like that has a low temperature with susceptibility to fluctuations in temperature and flow rate.
