STEAM GENERATOR

摘要

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.

1. 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.
