Abstract
A steam generator includes a tank having an inlet in a lower part for feeding a fluid, and an outlet in an upper part for discharging a vapor-liquid two phase flow. A heating unit heats the fluid in the tank thereby producing the vapor-liquid two phase flow. A porous cylindrical member projects from the outlet into an inside of the tank and functions as a rectifying unit that homogenizes vapor-liquid distribution in the vapor-liquid two phase flow before the vapor-liquid two phase flow is discharged from the outlet.
Claims6
A steam generator comprising:
- a tank having an inlet in a lower part for feeding a fluid, and an outlet in an upper part for discharging a vapor-liquid two phase flow;
- a heating unit that heats the fluid in the tank thereby producing the vapor-liquid two phase flow;
- and
- a rectifying unit that homogenizes vapor-liquid distribution in the vapor-liquid two phase flow before the vapor-liquid two phase flow is discharged from the outlet,
