Abstract
A steam generator having a channel for circulating heated fluid through a heat exchanger and having a channel for supplying water through the heat exchanger. The steam side of the heat exchanger is maintained at a pressure lower than the outside atmosphere and is heated by the heating fluid to a temperature more than the boiling point of the water at the lowered pressure. The water being introduced to the heat exchanger is heated to a boil. The steam produced is less than the boiling point of water in the atmosphere. A vacuum pump draws the steam from the heat exchanger and ejects the steam through a steam hose into atmospheric pressure. This rise in pressure is accompanied by a rise in temperature of the steam above the boiling point of water at atmospheric pressure.
Claims20
Apparatus comprising:
- a heater for heating fluid and for circulating the heated fluid through a heating tube;
- a supply of water fluidly connected to a water supply tube for supplying water through the water supply tube;
- a heat exchanger containing part of the heating tube and connected to the water supply tube for receiving the water and for heating the received water and generating steam;
- a hose;
- and
- a vacuum pump fluidly communicating with the heat exchanger and with the hose, the vacuum pump for drawing the steam from the heat exchanger and injecting the steam into a first end of the hose,
- wherein the hose outputs the steam through a second end thereof.
A method of generating steam comprising:
- maintaining a pressure in a heat exchanger at less than atmospheric pressure using a vacuum source;
- heating water in the heat exchanger under the less than atmospheric pressure past its boiling point at the less than atmospheric pressure to generate steam;
- and
- drawing the steam from the heat exchanger and discharging the steam into an environment at atmospheric pressure using the vacuum source.
A steam generator comprising:
- a supply of water;
- a boiler for heating a fluid;
- a heat exchanger fluidly connected to the boiler for receiving the heated fluid and fluidly connected to the supply of water for receiving the water, and for converting the received water to steam;
- a vacuum pump fluidly connected to the supply of water for maintaining a pressure of the water supplied to the heat exchanger at less than atmospheric pressure and for drawing the steam from the heat exchanger and ejecting the steam into an environment at the atmospheric pressure.
