- IMMERSION HEATER Filed May 22, 1967 Sheet In of 2 Fran/0 565551129, 59 2% 7 Jan. 14, 1969 F. GETHING IMMERSION HEATER Sheet Filed May 22, 1967 United States Patent Claim ABSTRACT OF THE DISCLOSURE
- An immersion heater having a housing is adapted to be seated on the edge of a tank containing liquid to be heated.
- the housing carries a chamber adapted to furnish fuel and air to a plurality of nozzles disposed in said chamber.
- An equal plurality of heat exchange tubes extend downwardly from the chamber and said plurality of nozzles to be immersed in the liquid in the container with the tubes being of diminishing size and there being provided a drain for collecting condensing products of combustion with the drain being in communication with that portion of the immersed tubes wherein the products of combustion are still primarily in gaseous form.
- the invention relates to an immersion heater and more particularly to a gas fired immersion heater having a plurality of heat exchange tubes to be immersed in a liquid to be heated.
- the immersion heater of the present invention is adaptable to many uses, it is particularly useful in providing a large source of heated water for car washes.
- a concrete tank usually open so as to be at atmospheric pressure which tank prov-ides the source of water to be used in the car washing operations.
- the water must be heated in order more satisfactorily to perform its function and the immersion heater of the present invention is particularly adapted for use in connection with such open tanks inasmuch as it is arranged to be seated on the upper edge of the tank with the heat exchange tubes used in connection therewith immersed in the water in the tank.
- an immersion heater particularly adapted to be seated on an upper edge of an open container for water which heater is provided with a plurality of tubes immersible in the water together with gas fired means for constituing a flow of hot gases through the tubes.
- FIG. 1 is a side elevational view partly broken away of an immersion heater embodying the features of the present invention
- FIG. 2 is a view like FIG. 1 taken from a position 90 therefrom;
- FIG. 3 is an enlarged detail view taken along line 3-3 of FIG. 2.
- an immersion heater 10 provided with a housing 11.
- the housing is provided with portions 12 and 13 adapted to seat upon the upper edge of a container (not shown) for liquid to be heated.
- the housing is arranged to be positioned above the upper level 14 of liquid in the container and is provided with a control panel 15 housing controls operative to response to temperature of the liquid to be heated to supply additional heat thereto or to cut ofi the source of heat when not needed.
- a plurality of gas nozzles 16 are located in a chamber 17 in the housing with the gas exited from the nozzles arranged to be ignited by a ribbon type pilot burner 18.
- the pilot burner is of the constant type, i.e.
- the control 15 senses the ignition of the pilot light and operates to cut ofi the flow of gas to the nozzles in the event the pilot light is extinguished. Pre-ignition of the pilot is achieved in the usual fashion by means of the electrode 19. Gas is supplied from a gas source 20 to a gas conduit 21 connected to each of the gas nozzles with the source being controlled, of course, by the control 15 as previously described. Air for combustion is supplied by a centrifugal blower 22 having a discharge conduit 23 connected to a distribution conduit 24 opening into the chamber 17. The flow of air through the conduit 24 is regulated by a damper 25 under the control of the control device.
- a plurality of fire tubes 30 open at one end into the chamber 17 and the flame from the gas nozzle 16 is directed downwardly into said open end.
- the tubes have a first vertical portion, as shown, which connects by means of an elbow 31 into a horizontal portion 32, constituting the lowest portion of the heat exchange fire tubes.
- the portion 32 is connected by means of elbows 33, 35 and 37 to a plurality of horizontal tubes 34, 36 and 38 which provide tortuous passages for the hot gases produced in the first vertical portion of the fire tubes.
- the horizontal portion 38 of the fire tubes terminates in an upwardly extending portion 39 which communicates with the atmosphere.
- the portions 30 and 32 of the tubes are of larger transverse diameter than the portions 34, 36 and 38. This provides a more uniform flow of gases through the tubes. As the gases transfer heat to the water heating the same, the volume of the gases decreases.
- the portion 32 of the fire tube is the lowest portion of the heat exchange assembly and each of the portions 32 of the tubes shown is connected to a common drain 40 which is connected in turn through a coupling 41 to a vertically extending pipe 42 opening to or connected with the atmosphere.
- the location of the drain 40 in the position shown enables it to operate as a collector for such condensed products, primarily water.
- the drain 40 is located quite close to the source of heat, i.e., that initial portion of the fire tubes wherein the gases passing therethrough are still quite hot, the condensed products of combustion collecting in the drain 40 are vaporized by the heat and pass out to atmosphere through the pipe 42.
- the heat exchange tubes With the products of combustion disposed of in the manner described, the heat exchange tubes will not become 3 blocked through the accumulation of condensed water therein nor will the corrosion which would otherwise 0ccure be encountered in immersion heaters of the present design.
- An immersion heater of the character described comprising: a housing adapted to be supported above a container for liquid to be heated; a chamber carried by the housing; a plurality of fire tubes each opening at one end to the interior of the chamber and each having a first portion extending downwardly from the chamber for immersion in said liquid, a second portion providing tortuous passages for hot gases, and a third portion extending upwardly from the second portion and communicating with the atmosphere; a plurality of gas nozzles in the chamber each directed into the open end of a different one of said fire tubes; means including a blower and a distribution conduit for supplying combustion air to said chamber to provide uniform air distribution to each gas nozzle; a drain connected to a lower part of said first portion for collecting condensed products of combustion; and means connecting the drain to the atmosphere.
