APPARATUS FOR SUPPLYING HEAT.

SPECIFICATION forming part of Letters Patent No. 536,667, dated April 2, 1895.

Application tiled December 6 1894. Serial No. 531,014f (No model.)

To all whom it may concern:

' Be it known that I, SAMUEL TURNER, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Apparatus for Supplying Heat, of which the following is a'specification.

My invention relates to an improvement in the method of and apparatus for producing heat in which a fluid of hydrocarbon, mingled with water, is utilized to support combustion.

My invention consists broadly in supplying a burner with mingled oil and water by confining the' supply of water in an air tight receptacle and introducing the oil-under head or pressure-into contact with the water intermediate of the water supply tank and the burner. v

. A practical apparatus for carrying this method into effect is represented in the accompanying drawing which shows, in vertical section, a lower tank for holding the water, an upper tank for holding the hydrocarbon, and a heater and conduits leading from the tanks to the heater.

The particular form of heater and its arrangement with respect to the supply tanks, and the shape and location of the supply tanksother than the location of the hydrocarbon tank at a higher level than the water tank-are matters of choice and may be varied to suit convenience.

A represents a support, which may be a column or the side of a wall or other suitable support for holding one or both of the tanks at the desired elevation. In the present instance, I have shown the support A as provided with a fixed bracket a for supporting the water tank B at the desired height and with an adjustable bracket a for holding the hydrocarbon tank 0 at a greater or less elevation with relation to the tank B, as may be desired.

Ihave represented the tanks B and O as made of glass, but the material employed may be metal or any other suitable material for holding the water and hydrocarbon, although it would be found convenient, in practice, to employ in connection with an opaque tank a transparent column to denote the height of bottom of the water tank B, on a slight downward decline, to the heater E within the lower chamber 6 of which the said pipe connects with a coil d, the said coil forming in the present instance a continuation of the pipe D, and the lower end of the coil (1 being provided with a nipple d, the orifice of which is directed upwardly in the coil (1, so that the flame from the nipple d which serves as a burner will come in contact with the different parts of the coil d when the apparatus is in operation. The lower end of the coil d is stopped so that the only opportunity of escape of the material from within the coil d is through the orifice in the nipple d.

A pipeF leads from the bottom of the hydrocarbon tank 0 downwardly to and communicates with the interior of the water discharge pipe D intermediate of the tank B and the burner d; in the present instance, at apoint (1 near to and outside of the heater E. The pipe F is provided with a stop cockf for shutting oE and turning on the oil supply. The upper part of the heater E is here shown as filled with refractory material e for retaining the heat supplied by the flame from the burner (1'.

The water tank B is made air tight, the supply of water to the tank being conveniently furnished by the pipe G, leading from the water main, or from any suitable water reservoir above the tank B, and said filling pipe G is supplied with a stop cock 9 for opening and shutting ofi the supply. For purposes of removing the oil, which accumulates in the tank B under the operation (to be hereinafter more fully set forth) I have provided the tank B with a short vent pipe I) provided with a stop cock I) and with a discharge pipe 1) provided with a stop cock b The hydrocarbon tank 0 is provided with a vent cat its top.

The operation is as follows: The tank 0, being filled with a suitable fluid hydrocarbonsuch for example as kerosene oiland the tank B being filled with water, and the supply and vent both out off by closing the cooks g and b, the discharge cock I) for emptying the tank B being also closed and the vent c in the tank C opened; the cock f may be opened to discharge the oil from the tank 0 into contact with the water in the pipe D. The vapor or fine stream of oil issuing from the burner d may be ignited and, as soon as its flame has raised the heat of the coil (1 and the material therein to'a considerable extent, preferably to a degree sufficient to convert the water in the coil (1 into steam, the mingled oil and water will escape from the burner d with great velocity in the form of invisible vapor and the flame will change to a blue or heat flame and the apparatus will continue its operation automatically until the oil or water (one or both) has become exhausted.

During the operation of the apparatus, it has been found that a portion of the oil discharged from the pipe F creeps back along the pipe D into the water tank B and accumulates above the water in said tank, as denoted at 0, thereby supplying the vacuum which the discharge of water from the air tight tank B would tend to produce, and by its pressure upon the water in the tank B,

forces the water to the burner against the back pressure of the steam from the coil.

While the size of the discharge pipes may undoubtedly be varied, without materially interfering with the operation of the apparatus, I have found that the following conditions produced eminently satisfactory results: The pipes F had each of them one-eighth of an inch bore and the oil tank 0 was adjusted to eight feet above the tank 13. Three quarts of kerosene oil, such as commonly purchased on the market, were placed in thetankO and the lower tank B was filled with water. The apparatus was set in operation and after burning twelve hours, the oil in the tank 0 had disappeared. Upon examining the tank B, I

found that one quart of oil had replaced an equivalent amount of water in the tank B and that two quarts of oil and one. quart of water had escaped in the form of invisible vapor from the burner to support combustion. I further found, during the tests which I made, that the flame was increased in size and force by elevating the oil tank 0 farther above the water tank B and that the flame was lessened in size and intensity by lowering the said oil tank with respect to the Water tank.

What I claim is- 1. Means for containing a body of water, means for containinga body of liquid hydrocarbon under head or pressure, means for transmitting pressure upon the body of water through the medium of the body of hydrocarbon, and means for bringing the two liquids into intimate contact in their passage to a burner substantially as set forth.

2. The combination with a burner and an air tight water tank in communication with the burner, of an oil supply tank, a conduit for leading the oil under head or pressure from the supply tank to the water at a point intermediate of the air tight water tank and burner and means for heating the mingled oil and water before reaching the burner, substantially as set forth.

3. In combination, a pipe coil, a burner located beneath the coil, an air tight water tank, a pipe leading from the water tank to the coil, an oil tank, a pipe leading from the oil tank to the water conducting pipe intermediate of the water tank and coil and means for regulating the discharge of the oil and water, substantially as set forth.
