1. A steam generating apparatus comprising:
a heater for heating a fluid and for circulating the heated fluid through a heating tube; a supply of water for supplying water through a water supply tube; a heat exchanger containing part of the heating tube that receives the heated fluid from the heater for circulation through the heat exchanger and returns the fluid to the heater through a return line as part of a closed loop, the heat exchanger being fluidically connected to the water supply via the water supply line in which the heat exchanger receives the water from the water supply, for heating the received water and for generating steam; a vacuum pump fluidly connected with the heat exchanger and an exhaust hose, the vacuum pump being coupled to the heat exchanger for drawing the generated steam from the heat exchanger and injecting the steam into a first end of the exhaust hose, in which the heater heats the fluid to a temperature less than the boiling point of the water at a standard atmospheric pressure and the vacuum pump maintains a pressure in at least a portion of the water supply line less than the pressure of an atmosphere immediately outside of the apparatus; wherein the exhaust hose outputs the steam through a second end thereof. |
