Abstract:
A method for heating a body of a liquid from a first lower temperature T1, to a second higher temperature T2, comprising the steps of:compressing a gas; heating the compressed gas to a third temperature T3, higher than a second higher temperature T2; introducing the compressed heated gas into an elongated heating conduit disposed in a body of a liquid having a lower temperature T1 such that the gas expands to induce a flow of the liquid in the heating conduit and raises the temperature of the flowing liquid in the heating conduit to a temperature greater than said second temperature T2, and then delivering the heated flowing liquid from the heating conduit into the body of the liquid to raise the temperature thereof toward temperature T2 at a heat transfer rate that is in accordance with the velocity of the heated liquid flowing from the heating conduit into the body of the liquid.
