Abstract
An injection head introduces H.sub.2 and O.sub.2 into one end of an elongate combustion chamber. At the same time, water is injected into the chamber through peripheral ducts to form a water curtain, or through inlets in the injection head, or through apertures facing away from the injection head in water-cooled tubing extending in a plane perpendicular to the chamber axis.
Claims7
A steam generator, comprising
- (a) means defining a combustion chamber having a longitudinal axis;
- (b) an injection head for introducing gaseous hydrogen and gaseous oxygen into one end of said combustion chamber;
- (c) tubing means extending within said chamber in a plane substantially perpendicular to the longitudinal axis thereof;
- (d) means longitudinally partitioning said tubing means into a first compartment adjacent said injection head and a second compartment remote from said injection head;
- (e) means for supplying water to the first compartment, and means for discharging water from the first compartment so that water is conducted through the first compartment in order to cool the tubing;
- and
- (f) means for supplying water to the second compartment, said second compartment having a wall portion containing apertures for injecting water into the combustion chamber away from the injection head.
