Description

April 3, 1934. D. c. SEMMER 1 PRODUCTION OF EXPANSIVE FLUID Filed April 5, 1929 6) Jam: 12167562722716?" INVENTOR ATTORNEY Patented Apr. 3, 1934 UNITED STATES PATENT OFFICE 2 Claims.
This invention relates to the production of expansible fluid by the transfer of heat by convection and conduction, the general object of the invention being to provide means for heating the vapors in the vapor space of a boiler or the like and conducting the heated vapors through a conduit which has portions in both the vapor space and liquid space of the boiler, with means for spraying liquid into the vapor space where the spray is subjected to the heating action of a burner, which also acts to heat the vapors and the walls of the conduit in said space.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawing which shows a sectional view of an apparatus for carrying out the invention.
In this view, the numeral 1 indicates a boiler which contains liquid, as shown at 2, the space above the liquid forming a vapor space 3. A pipe 4 extends from a source of liquid supply into the vapor space and that portion of the pipe within the boiler is formed with the perforations 5 in its lower part so that the liquid flowing through the pipe is sprayed on to the surface of the liquid in the boiler. A coil 6 is arranged in the boiler,
with portions of its convolutions extending into the liquid and other portions arranged in the vapor space. The inlet end of the coil is formed with a flaring mouth '7 so that vapors from the space 3 can pass into the same and the other end of the coil is connected with a discharge pipe 8 which leads the vapors to the point of use.
A burner 8 is arranged in the vapor space and is supplied with fuel through the pipe 9 and with air through the pipe 10. This burner is so arranged that the products of combustion will be ejected into the major portion of the space 3 and against the perforated part of the pipe 4 as well as against portions of the convolutions of the coil.
The heat propagated by convection is distributed through the vapor portion of the boiler. The vapors pass into the coil and flow through the same to the outlet 8, thus heating the walls of the coil and thereby heating the liquid through the transfer of heat thereto by conduction.
From the foregoing, it will be seen that I utilize the combined principles of convection and conduction in the transfer of the heat produced by the burner to the liquid and vapors and thereby produce a condensible vapor very quickly and with the minimum consumption of fuel.
Owing to the simple nature of the device, it can be made of light weight so that it will be portcs able and thus used as a furnace or heater in cases where such a furnace must be moved from one place to another.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the 7 appended claims.
What I claim is:
1. An apparatus of the class described comprising a boiler having liquid therein, with a vapor space above the liquid, a spray pipe extending into the vapor space, means for introducing liquid into said pipe, a coil in the boiler having portions of its convolutions extending into the liquid and other portions extending into the vapor space, an outlet pipe connected with the coil, the other end of the coil being in communication with the vapor space and a burner for heating the spray pipe, the portions of the coil in the vapor space and the vapors.
2. An apparatus of the class described comprising a boiler having liquid therein, with a vapor space above the liquid, a spray pipe extending into the vapor space, means for introducing liquid into said pipe, a coil in the boiler having portions of its convolutions extending into the liquid and other portions extending into the vapor space, an outlet pipe connected with the coil, the other end of the coil being in communication with the vaport space, and unitary means for heating and diffusing vapor in the vapor space of the boiler and heating liquid being discharged from the spray pipe and being constantly added to the liquid first named.
