ABSTRACT:
A superheated steam generator for crude oil recovery systems includes a centrally disposed second stage electric superheated steam generating tank surrounded and fed by a plurality of radially spaced first stage electric steam generating tanks. A primary manifold system supplies water to each of the first stage tanks and includes a central reservoir communicating with a plurality of constriction fittings. Each constriction fitting includes a tapered nozzle directed interiorly of the manifold toward a removable plug closing an associated inspection orifice permitting cleaning of the manifold and removal of the associated constriction fitting. Tubes coupled to opposite external ends of the constriction fittings deliver water to the first stage tanks, and are coupled to elongated tubes having portions extending longitudinally interiorly of the first stage tanks. A rigid tubular sheath coaxially surrounds and protects each of the last mentioned tubes, and defines a steam output passageway between the sheath and the mouth of each first stage tank. Steam from the first stage tanks is transmitted to the second stage tank by a plurality of radial equal length conduits extending between each first stage steam output passageway and the central manifold and by a pipe connected to the central manifold and extending longitudinally interiorly of the second stage tank. A steam output passageway is defined between the latter pipe and a rigid pipe extending between the central steam manifold and the mouth of the second stage heater tank body.
