ABSTRACT:
Disclosed is apparatus for dispersing water within a flowing stream of fuel oil, to produce an oil and water emulsion which improves combustion efficiency by as much as 15 percent. The apparatus includes a pressurized supply of water, a differential pressure regulator, a proportioning or tracking valve, and an emulsifying mixer. The differential pressure regulator provides water to the tracking valve at a pressure which is a constant amount above that of the oil just upstream of the mixing point. The tracking valve has two chambers. A first chamber receives oil and contains a float which moves in response to oil flow therethrough; a float extension penetrates from the first chamber into the second chamber which receives the water, and causes movement of a needle shaped element therein, to vary the water flow path area. The operative valve elements are coaligned and configured especially for responsiveness and accuracy in proportioning. The apparatus further includes a control and valving system which prevents operation of the water injection components when the oil flow is inadequate. Also prevented is inadvertant passage of oil into the water processing components.
