Specification of Letters Patent.
atcnted Main 3921 Application filed December 13, 1919. Serial No. 34 2,1738.
To aZZ whom it may concern:
Be it known that 1, JOHN H. GuAYsoN, a citizen of the Unlted States, residing at Athens in the county of Athens and State rinoi all )rooa ated b convection and radiation. Gas heaters of the type referred to operate, as the name indicates, in the main, on the principle of radiation: The gas flame is passed through a body of refractory material forming a mantle and thereby heated to glowing condition. The greater part of the heat energy is absorbed by the material of the mantle and radiated substantially as fast as it is absorbed. A considerable portion. of the available heat energy, however, is carried out by the products of combustion into the flue and wasted.
It is the principal object of the invention to provide a gas heater in which a very high percentage of the heat of combustion is utilized for the purpose for which it intended and only a relatively small percentage is allowed to escape as waste.
My invention, briefly stated, consists in using a secondary radiating system in the path of the products of combustion for the purpose of absorbing and radiating such available heat ener y which would normally go to waste in heaters of the usual kind.
For a fuller understanding of the invention reference is had to the accompanying drawings, in which Figure 1 is a side elevation ofa gas heater, a part being shown in section;
F 2 is a front view of a heater section, parts being removed to show the principal feature of the invention.
F 3 is sectional view of a back brick formed acct ":ding to the invention; and
1' front and rear views of J. represents gas burner tube which may es of any suitable or preferred form, 2 being the manifold for feeding the gas to a plurality of burners. Upon a support 3 are assembled a back brick t and a series of radiators or mantles 5 in front thereof.
The front face of the back brick is slightly overhanging, forming an angle of approximately five degrees with the vertical, and the rear surface of the radiator 5 is upwardly receding to the same extent to fit against the back brick. J
The radiator 5 has two preferably imperforate side walls 6 and a front 'all 7 and a rear wall 8, both of suitable lattice work. The rear wall is preferably provided with slits 8 and small projections S.
The front face of the back brick is formed with a relatively large number of diagonally extending channels, or grooves 9 defining; outwardly tapering;- studs or projections ll) arranged in stage i l relation. This feature is principally identified with the invention.
The operation is as follows:
The burner flame passes upwardlv into the radiator and heats the material of the radiator to glowing condition. The products of combustion escape partly through the rear wall 8 of the radiator and in passing upwardly through the :iig-zap; shaped channels 9 they envelop the projections 10 and give up part of the sensible heat energy thereto. The absorbed heat is again radiated forwardly through the interstices of the radiators 5 and is propagated into the room together with the heat iven off by the radiator per 86. The projections 10 thus form in effect a secondary radiating system in addition to the primary system of the radiators 5.
The projections 10 thus continuously absorb and radiate heat which would otherwise be lost. They at the same time act as battle elements to retard the flow of the heated gases upwardly into the flue and thereby additionally promote the abstraction of heat from the products of combustion Due to the bathing effect of the projections 10 the hot gases are more uniformly dis tributed throughout the interior of the radiator 5.
The projections 10 also act as deflectors. the front face of the back brick is over hanging, the hot gases in passing" upwardly partly strike the tapered studs and are de ilected forwardly againstthe rear wall 8 of the radiator or even through the slits 8 thereby transferring more heat to the radiator.
The channels 9 allow the products of combustion to expand and give the flame full freedom and thereby promote complete combustion of the gaseous mixture.
By the arrangement described the prodnets of combustion passing out through the top of the radiatorand through the channels 9 are relatively cool. The greater part of the sensible heat has been thrown out, principally by radiation, to the front into the room.
Jihe form of the channels and the resulting studs or projections may of course be varied. Preferably they should, however, be so formed that the projections have outwardly taper ng surfaces operating to defiect the gases forwardly.
I prefer to form recesses 10 in the projections 10 defining thin walled radiating elements in order to promote the rate of radiation therefrom. By this or similarmeans the proportions may be locally heated to a glowing condition and the rate of radiation correspondingly increased.
' I claim:
1. In a gas heater, the combination of a radiator and a back brick having on its ever/e radiator and a back brick having on its front surface outwardly tapering projections arranged in staggered relation and formed to define thin-walled radiating elements.
4'. In a gas heater, the combination of a radiator and a back brick having on its front surface projections formed at their ends to define thin-walled radiating elements.
5. In a gas heater, the combination of a radiator and a back brick therefor, the front surface of the back brick being forwardly ments and the rear wall of the radiator being similarly inclined to fit against the brick.
6. In a gas heater the combination with a radiator, of a back brick having a channeled surface defining projections, said projections being recessed to form relatively JOHN H. GRAYSON.
