A rapid response steam generator wherein steam pressure is generated by moving fluid in contact with preheated metal in a heat exchanger having vertical grooves surrounding a downwardly expanding central passage, the passage having an obturator urged upwardly for directing the fluid being heated into the vertical grooves. The obturator is movable downwardly for releasing excess pressure into the central passage. Liquid is stored in a cylindrical housing below said heat exchanger. Steam is discharged through upwardly directed discharge means in the cylindrical housing positioned below said heat exchanger. Liquid is stored in said cylindrical housing and is pumped to the said heat exchanger for steam generation. Superheated steam, if formed in said heat exchanger, passes through fiberous or particulate matter saturated with liquid in the cylindrical housing for generating additional steam.
