A steam generating apparatus which includes a novel gas burner and consisting of a pair of spaced coaxial cylinders, the outer of which is of considerably greater axial length than the inner and both of which are provided with apertures for admixing the gas with air. The inner cylinder functions as an integral pilot burner which is highly stable. The steam generating apparatus heats water to provide steam, heats it still further, then condenses the steam into liquid to assist in the formation of still more steam.
