11 Claims.
This invention relates to gas burning apparatus adapted for heating furnaces generally, and has for one of its objects the provision of a gas burning apparatus of improved and novel construction.
More specifically the present invention provides a construction wherein deflector rings are provided for directing the damper-controlled secondary air over the burner ports.
Another object of my invention is the provision of a gas burning apparatus in which refractory radiants are employed for absorbing heat from the gas flame and transformingit into radiant heat energy, these radiants being provided on their exterior with grooves disposed diagonally and roughly providing a helical formation, the effect of which is to impart a swirling motion to the combustion gases thereby retarding the speed of movement of these gases through the boiler and causing a wiping contact of the combustion gases with the inside walls of the boiler, to promote the efficiency of the burner.
A still further object of my invention is the provision of a gas burning apparatus adapted to be installed through the ashpit of a furnace, a seal being provided around the outside of the burner head between it and the wall of the furnace so that the ashpit section of the furnace or boiler is very effectively sealed at the grate line, thereby preventing heat losses through this part of the boiler and eliminating seepage of stray excess air currents at this point.
In the drawings accompanying this application:
Fig. 1 is a part sectional side elevational View of my improved apparatus as installed in a furnace;
Fig. 2 is a view similar to Fig. 1 but with additional parts broken away to show structural details;
Fig. 3 is an end elevational View of the rear end of the apparatus;
Fig. 4 is a section on the line 4--4 of Fig. 2;
Fig. 5 is a section taken substantially on the line 55 of Fig. 2; and
Fig. 6 is a sectional plan view.
Referring to the drawings in detail, F designates a furnace which, for example, may be of the ordinary house heating type. My improved apparatus which is shown installed in this furnace comprises inspirator tubes I, each provided with a head 2. These heads are arcuate in plan and. the top thereof provided with gas ports 3. This construction provides, therefore, a circular burner. The heads 2 are provided with lugs 4 and 5, the former supporting a radiant-supporting plate 6, and the latter an air deflector ring I, the ring I completely surrounding or encircling the burner. The periphery of the radiant-supporting plate 6 is formed to provide an air deflecting ring 8.
From an inspection of Fig. 5, for example, it will 5.-:
be apparent that the rings 1 and 8 are both spaced from the outer walls of the heads 2 to provide passages 9 for the travel of secondary air as will be brought out hereinafter.
Each of the inspirator tubes l is provided with 10' an integral leg l!) adapted to be bolted to the floor for instance and to support the Whole structure so far described.
The burner head and its associated deflector rings, etc. are positioned in the furnace at about I the grate line, the tubes extending from the ashpit to the furnace exterior. To prevent seepage of stray air currents past the exterior of the burner head I provide a seal shown at H, in the form of cement or refractory, and supported on the air deflector ring '2. The furnace Wall has been designated l2.
The inspirator tubes 5 extend along the interior of a secondary air-conducting casing l3 which rests on the floor and extends through the ashpit opening for a short distance into the ashpit l4 itself. The outer end of the casing I3 is closed by a plate I5, equipped on its inner face with suitable means It for receiving the outer ends of the inspirator tubes I and with adjustable gas valves I1, 00 inlets l8 for primary air, and regulators Is for the regulation or adjustment of the primary air. The gas inlet pipe is shown at Eli.
This construction provides for the proper regulation of the primary air and gas.
2! designates an electrically operated gas valve which is of usual well known construction and as usual controlled from a room thermostat. The gas valve 2! as will be understood automatically opens and closes in accordance with the demands of the room thermostat. As this structure is Well known and constitutes no part of the present invention it will not be described in any more detail.
22 designates a damper operating lever adapted to be rocked by operation of the gas valve 2 l, and attached through spring and chain 23 and 24 to a damper 25 in the end plate l5 of the casing l3, so that as the gas valve is opened the damper 25 will fall open to admit secondary air to the casing, and as the gas valve closes the damper will be pulled closed. The extent of opening of the damper 25 is adjustable by a screw 26.
The pilot shown at 2? underlies the deflector ring 8 so as to be protected from the heat of the burner.
The plate 6 is provided in its upper face with a concentric groove 28 for receiving upwardly extending and outwardly flaring refractory radiants 29. These radiants are made in sections provided exteriorly with grooves 39 extending in a general diagonal direction with respect to the horizontal and as a whole providing helically disposed grooves for causing the products of combustion to swirl in their passage upwardly through the combustion chamber of the furnace thereby retarding upward movement of these gases, and increasing the contact of the combustion gases with the wall l2 of the furnace.
