To all whom it may concern:
Be it known that I, Luonunsu Gino-Mans, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Gas Furnaces, of which the following is a specification. a
This invention relates to improvements in hot air furnaces of the gas heated type and has particular reference to a gas heating unit forming a part of the furnace, which unit is constructed in a novel and efficacious manner in-order to prove more efiicient in operation.
An object of the invention is to provide an improved gas heater for furnaces of the character described wherein the products of combustion are maintained separate from the heated air which is conveyed to the different rooms of a house or dwelling, the products of combustion being carried off through a chimney or flue. V
Another object of the invention is to provide a gas heater construction of the character described wherein the draft in all circulating parts of the heater is equalized and such parts of the heater are therefore uniformly heated with the result that a thorough combustion of the gases is provided for, the products of combustion travelling substantially an equal distance from the point of their formation to the point of discharge thereof from the heater, regardless of the number of conduits or passages through which the products of combustion are directed.
Heretofore it has been the practice to cause the products of combustion from a gas burner to circulate through passages or conduits in order that air surrounding the passages or conduits. will be heated and may be taken off to heat various rooms or parts of houses or dwellings, the products of combustion usually discharging into a chanr her having an outlet leading to a flue or chimney. The outlet is located either at an end or side of the drum or chamber or is such that certain of the passages or fluesare close to the outlet and have a greater draft action set up therein than is the case with others of said flues. Thus the products of combustion will more readily pass through those of the passages orconduits which have discharge ends located closer to the outlet above mentioned and such passages or 0011- duits will be heated to a greater degree than the other passages or conduits. The heated parts of the furnace which are depended upon to heat the air surrounding them are therefore. unevenly heated and full heating efficiency is not obtained. Furthermore by producing a greater draft near one part of the burner than at other parts, the burner will not function with full efficiency in that the combustion of the gas is irregular at certain points of the burner.
I have found that by causing the prodnote of combustion to travel substantially unequal distance from the burner through a plurality of flues or passages to the point of the discharge of said products of combustion from the heater, that the draft will be equalized throughout such heater parts and said parts will be uniformly heated. Also the combustion of gas at the burner will be uniform and thorough.
With the above mentioned and other objects in view, the invention consists in the novelconstruction and combination of parts hereinafter described, illustrated in the accompanying drawings,and set forth in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be re sorted to without departing from the spirit or sacrificing any of the advantages of the invention.
Referring to the drawing:
Fig. 1 represents a cross sectional View of a furnace constructed in accordance with the present invention, showing the gas heater in. top plan.
Fig. 2 represents a vertical sectional view of the furnace and heater of the invention.
In carrying out one embodiment of the invention I provide a burner casing or cha1nher and mount a burner adjacent the lower end of said casing. Arranged radially on the outside of said casing are a plurality of flues or pipes whose terminals are respectively communicated with the upper end of the casing and a chamberor collection drum at the lower end of the casing. The heat and. products of combustion pass upwardly from its upper end heated air is directed to the various parts of a house or dwelling as the case may be. The collection drum or chamber at the lower end of the gas heater casing is provided with an outlet opening which measures the same distance throughout all the flues or pipes to the burner, or, in other words, to the point where the combustion of the gas talres place. Preferably this discharge opening is in the center of the lower side of the chamber and is in communication with a flue leading to a chimney, (not shown). Thus the draft set up is of suii'icient intensity to force through the various flues and within the casing and burner causing all flues and all parts of the burner through which the heat and products of combustion pass to be uniformly heated.
It will thus be seen that the size of the heater may be varied as d sired and that any number of radial flues or pipes may be employed without disturbing the equalization of the draft action through the circulatory parts of the heater.
In the embodiment of the invention shown in the accompanying drawing, the furnace comprises a main furnace casing 1, from the upper closed end of which a plurality of hot air fines or pipes 2 extend, which flues or pipes are to be directed to various parts of a house or dwelling in which the furnace is installed. At the lower end of the casing 1 are a plurality of screened air intake openings 8. Located within the casing 1 is a gas heater for heating air in the casing 1. This heater comprises an upright cylindrical casing 4, closed at its ends and containing near its lower end gas burners 5 and 6. Pipes 7 lead to said burners through the casing from a source of supply of gas, not shown, the burners being controlled by the usual valves 8. Immediately below the burners is a false bottom 9 between which and the bottom 10 of the cylinder there is defined a collection drum or chamber 11. A plurality of pipes or flues 12, in this instance radially arranged exteriorly of the casing 4', are connected at their upper ends with open ings 13 provided at the upper end of the casing and at the lower end with openings l-i in the cylindrical wall of the chamber or drum 11. These fines or pipes project considerably outwardly from the cylindrical wall of the gas heater asing and provide for a rapid and effective heating of the air in the furnace casing 1, due to their arrangement and location. Centrally of the lower side of the chamber or drum 11 there is provided an outlet opening 15 from which a discharge pipe or flue 16 extends to a chimney or flue, not shown. The opening 15 is so arranged that the distance from the burner to said opening through each of the fines or pipes 12, is substantially the same. This condition will obtain regardless of the number, size or location of the flues, provided they discharge into the chamber through openings such as the ones M which are substantially equidistantly spaced from the discharge or outlet opening 15. The arrangement provides for an equal draft throughout the fiues with the result that the fiues will be uniformly heated and the burners will operate more effectively throughout their burning areas. If the outlet opening were located closer to certain of theopenings let in the drum or chamber 11, a greater suction or draft action would be set up through the flues which are connected to said closer openings with a result that the other flues would not handle an equal share of the circulation and would not be heated to the same temperature as the first named lines.
I claim:
A heater comprising a burner casing closed at its upper and lower ends, a false bottom mounted within the casing at a point spaced above the lower end of the casing and defining between it and the lower end a collection chamber, said casing having a plurality of equidistantly spaced openings disposed between the lower end and false bottom, a plurality of similarly arranged openings adjacent the upper end of the casing, a burner mounted within the casing above the false bottom, said casing having a centrally disposed outlet opening at its lower end, an outlet flue in communication with the opening, a plurality of upright flues arranged in a circular series around and spaced from the casing, lateral extensions at the ends of said fiues communicating with the openings at the upper and lower ends of the casing, another casing surrounding the first named casing and last named flues and being provided with hot air discharge openings at its upper end and atmospheric air intake openings at its lower end.
