ABSTRACT:
A low pressure steam generator comprising a horizontal coil of tubing having a single upper steam outlet header and a pair of lower water inlet headers on opposite sides of the coil. Curved taps connect the successive turns of the coil with the steam header, and curved taps connect the water headers alternately to the coil turns to give a structure which is resistant to differential thermal expansion and which is minimally susceptible to surging, pressure variation, and entrainment of water in the steam input.
