12 claims. (ci. 15a-1.5) f
This invention relates to air registers or the like and more particularly to an air register for use in a burner of the general type disclosed in E. H. Peabody Patent 1,628,424, dated May 10, 1927, for Apparatus and method for burning liquid fuel.
The air register may take the form of a casing having peripheral doors through which air for combustion is admitted. The doors control the direction and speed of the air and are adjusted to cause the same to form a rotating mass of air within the air register having a speed and rotation giving a degree of turbulence best adapted air and fuel for combustion.
An object of the present invention is to provide, in an air register, novel and improved means for independentlycontrolling the direction of rotation and the speed of air flow desired degree of turbulence. l I
In accordance with the present invention, the above and other related objects are accomplished by providing a plurality of independently controlled sets of peripheral air doors which are arranged adjacent each other and are in parallel with respect to the air flow. Both sets of doors are mounted for substantially 180 rotation with an overlap for completely closing ofi the air flow in each closed position. In this way either a clockwise or a counter-clockwise rotation may be imparted 'to the air passing through either set of so as to obtain anyA doors and the speed and direction of air iiow through eachset may be accurately controlled.
If, for example, the burner is to be operated at a very low capacity,`one set of doors may be completely closed so that all of the air for combustion passes through the second set of doors. On the other hand, when operated at maximum capacity, both sets of doors may be utilized for air` flow if desired. In this way the air admission area may be varied without changing the angular setting of the doors.
By this arrangement it is also possible to maintain a predetermined speed of air flow which is independent of the direction of rotation of the air, because both the direction of rotation and the speed represent a composite effect of the two sets of doors. For example, if both sets of doors are open to their maximum position, that is, are extended radially, a fixed quantity of air passing therethrough would have minimum speed and would enter the burner without rotation in either direction. On the other hand, if one set of doors is adjusted to a minimum opening for air rotation in a clockwise direction and the other set of doors is adjusted to a minimum opening in counterclockwise direction, air would pass ata high velocity through both sets of doors. However, the opposed rotation of the air passing through the two sets of doors would tend to neutralize the rotational effect of the mass of air within the register and would maintain an air iiow within the register without substantial rotation, the net result being to increase the speed of air ow without changing the resultant rotation. Obviously, intermediate adjustment could be made to obtain substantially a continuous range of adjustment froml minimum to maximum speed without substantial change in the resultant rotation of the air within the register.
The two sets of doors may also be set to produce two layers of air rotating either in the same or in opposite directions. tacts the fuel may thus have diiferent characteristics from the other layer which may represent tertiary air combining with the fuel nearer lthe burner throat.
It will be obvious that by a suitable adjustment .of the two sets of doorsV any desired combination of speed and degree of rotation may be obtained.
The nature of the invention will be better understood by referring to the following description, taken in connection with the accompanying drawings in which aspecic has been set forth forpurposes of illustration.
In the drawings:
Fig. 1 is a longitudinal section of a burner embodying the present invention;
Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1 showing the arrangement of front plate and adjusting means; and
' Figs. 3, 4, 5 and 6 are partial transverse sections taken on the line 3-3 of Fig. 1 showing the air register doors in diiferent positions.
, Referring to the drawings more in detail, the invention is shown as applied to a burner for a furnace having a combustion chamber provided with a wall I0 of the usual refractory material and an opening II forming the burner throat. A
Wall plate I2 is positioned I Il and to this plate is over the refractory wall secured a fuel ring I4 extending around the burner throat II and having openings I5 through which fuel may be admitted to the throat. 'I'he fuel ring I4 may be attached by means of brackets I6 which may be secured by bolts I1 to the wall plate I2.
The air register is shown as having a front plate 20 secured by bolts 2l to a plate 22 which is spaced from the wall plate I 2 to form a plenum chamber 23 therebetween in which air is supplied The layer which first conembodiment thereof 3` under pressure to the register. Theregister is provided with a back plate 24 which is secured toand spaced from the front plate 29 by spacing bolts 25l and is provided with a cylindrical extension 26 of any desired length terminating in a flange 21 which is posltionedadjacent the fuel ring I4. but is not secured thereto. Fuel is suppiiedto the fuel ring I4 by means of an inlet duct v2,8 which extends through the plate 22 to the front of the register and is provided with a control valve 29.
In certain embodiments, such as, for example,
an air register for use at atmospheric pressure,
the register may be supported from the plate l2 in which event the plate 22 may be omitted.
The register front plate 2li is shown as provided with a hub 30 in which an atomizer barrel 3| is mounted and is secured by means of a set screw 32. The atomizer barrel is provided with a diffuser 34 and an atomizer tip 33 which is arranged to direct a stream of finely divided fuel into the burner throat. The atomizer barrel 3l also carries a coupling means 35 containing a fuel connection not shown.
The atomiz'er barrel, if for liquid fuel, may be of the type disclosed more in detail in the Peabody patent above identified and may comprise, for example, meansfor supplying fuel under pressure to the atomizer tip and for discharging the same in a finely divided spray. The operating capacity may be varied by varying the supply pressure or by returning a portion of the-fuel `from the atomizer tip to the fuel pump and controllingthe pressure in the fuel return line as more fully described in said patent. Other fuel supply means may be used for burning various types of gaseous, liquid or pulverized fuel, as shown, for example, in S. T. Warner Patent 1.790,-
395, dated Jan. 27, 1931, for Fuel burner and J.
Dunn, Patent 2,320,575, dated June 1, 1943, for Fuel burner.
For controlling the velocity ofthe air supply from the. plenum chamber 23 to the interior of plate 24 and are provided at their forward ends' with pinions 45 meshing with an annular rack 41 which is rotatable in brackets 48 attached to the front plate 20 to cause all of the doors to be adjusted in unison. An adjusting handle 49 is attached to one of the shafts 45 for controlling this adjustment.
The handles 49 and 53 cooperate with indicator and locking plates 59 and 59 respectively for locking the respective sets of doors in their adjusted `positions. In the form shown the plates 58 and 59 areprovided with locking notches which are 4 spaced more closely as the doors approach their closed positions so that a liner adjustment may the different operating positions. It is also to be noted that counter-clockwise rotation is obtained through both sets of vdoors when both handles 49 and 53 are moved to the left of the vertical center line and clockwise rotation is obtained when the handles are moved to the right of this center line as viewed in Fig. 2.
Other means may be used for actuating the doors in unison such as connecting links as shown in Dunn Patent 2,320,576, dated June 1, 1943, for Air register.
In some instances individual adjustment of each door may be desired in which event the annular racks 41 and 52 may be omitted and separate adjusting handles and quadrants may be provided for the individual doors.
In the embodiment shown all of the doors 40 and 4I are substantially fiat as shown in Fig. 3 and are mounted symmetrically on the respective sleeves 50 or shafts 45 so that they overlap and form a substantially continuous wall when ad- Justed to closed position in either direction. The doors are made with symmetrical surfaces on the two sides of the axis of rotation so that the inner peripheral wall formed thereby when closed arid the shape of the air passages therebetween when open will be the same regardless of which side of the door is adjusted to face the interior of the register.
Operation In the normal operation of the burner liquid or other fuel is supplied to the atomizer barrel 3l and gaseous fuel is supplied through the duct 28 to the throat ring I4. Ii only gaseous fuel iS to be burned the atomizer barrel '3| may be retracted. r I
With the burner in operation suitable adjustment is made of the two sets of doors 40 and 4I by means of the control handles 49 and 53. As pointed out above, by suitable adjustment of the two sets of doors any desired combination of air speed and air rotation within the burner may be obtained. The two sets of doors may be adjusted to cause the air-passing therethrough to rotate in the same direction or in opposite directions and in various degrees according to the operating requirements in each instance.
While two sets of adjacent parallel doors have been shown for purposes of illustration, it is obvious that additional sets may be provided as conditions require also that the direction of rotation of the air may be reversed when required without taking the burner out of operation.
Although a specic embodiment of the invention has been'shown for purposes of illustration, it is to be understood that the invention is capable of various uses and that changes and adaptations may be made therein as Iwill be readily apparent to a person skilled in the art. The invention is only to be limited in accordance with the scope of the following claims.
