Abstract:
Provided is a steam generating system effective to rapidly and momentarily respond to a drop in steam pressure when utilized in connection with a steam-operated device. Super-heated steam is passed from a heating unit to a vaporization chamber in which a liquid-saturated cartridge is positioned and through which super-heated steam is passed. In addition, a heat storage and liquid supply means are provided above the cartridge whereby, upon a drop in pressure in the generating system, steam is rapidly raised to a desired, predetermined pressure. Steam in the system is recycled through a superheating chamber and is conveyed back into the vaporization chamber, this for a duration in which the steam pressure is below the set predetermined level. Control means are provided to regulate ratio of fuel, typically powdered fuel, and air, typically oxygen or oxygen-rich air. Also controlled is the rate of vaporization and the recirculation of steam in the heating unit.
