JILL-Nl SAUYAGETy OF PARIS, FRANCE.
GRATE FOR GAS PRODUCERS,- .'FURNACES, ANI)l THE LIKE.
Application led June 3, 1924, SerialtNo.
This invention relates to grates of the type used in `all classes of gas-producer plants, including those of the Siemens variety, in furnaces, ovens, boilers and the like, and of the kind in which the clearing or cleansing of the fire from'ash, clinker and the'like is eected mechanically.
Grates for use'. in .gas-producers as at present constructed, require, on account of their form, circular movements to efect the before mentioned clearing or cleansing of' the tires. This makes the construction cumbersome, and the result 1s imperfect. Moreover, an excess o carbonio acid 1s produced,which leads to the excessive* forma-` portions of the bars.
' tion of slack.
The present invention Vprovides meansV for clearing the tires in an even and complete manner, andA also causes a decrease in.
the amount ofcarbonio acid formed, this decrease being such that the troubles due to the excessive production of slack are overcome.
A grate constructed according to the inventlon comprises a serles of hollow fire bars, so mounted that they can turn about their longitudinal axes. These bars are located in close proximity to one another, and may have an oval, triangular, or other polygonal, or circular shape in cross section, with projections on one half of the surface, the arrangement being such that the projections on one iire bar areadapted to register or co-operate with those on a neighboring bar, when thebars are turned. Tn order that the invention may be clearunderstoodit will now be described with reference vto the accompanying drawings which-"illustrate by'way 'of example, a grate and arrangement of lire bars made according tothesaid invention.
Fig. 1 shows, in cross section, a grate.l -with hollow partly star shaped fire bars.
Fig. 2 shows the position of these bars during the clearing or cleansing operations.
Fig. 3 shows the position of the, bars when the motion of rotation is continued.
F'g. 4 shows a side elevation 'of the hollowzlire bar.- .Y e
Fig." 5 is a top planofa portion of the grate surface with the re bars brought i turned in one direction or the other by 717,503, and. in France November 21,' 192e.
Fig. 7 is a top plan of the suface of the lire bar showing holes arranged in quincunx formation.
Figs. 8, 9 and l() show various elevations and sections of a gas-producer with a mechanical grate fixed therein.
. In `the construction illust-rated in theI drawings, the hollow fire bars' a. are arranged horizontally f adjacent to one another. As will be seen from the cross. sections the bars are provided with projecting teeth b. Air is supplied to the hollow interior l, of each bar, and passes through outwardly extending holes 2 arranged in the form-illustrated-on the semi-cylindrical The hollow bars may be' mounted on a frame 3, in such a waythat they4 can be vrollers 4 running upon extension rails 5, so that it ycan abe easily drawn out of or pushed into the gas-producer.
A gear Wheel 6 is mounted on the forward end of each of the fire bars, and a transverse bar with a worm or corresponding gears is provided, so that by turning a single bar all the tire bars can be rotated.
They may be turned continuously or peri-f odically. p
The revolutions of thelbars cause each pair to cooperate in such a way that the teeth of the said bars catch the cinders, i Y
break them up and deliver them between the bars into the ash box. -By this regular movement, the res are regularly cleared of cinders', and at the same time a regular current of air is supplied through the holes 2. j
The operation of the gas-producer` is as follows v Air under pressure, with or without the addition of steam, is supplied through a v8,"a d conducted into the hollow spaces 1 in each ofthe tire bars,- whence' it blows through the holes 2 in the semi-cylindrical portions into the gas-producer.
During normal working, the Afire bars are `in fthe positions shown in Fig. 1. l
To clear or cleanse the tire, the bars are means of the gearin ,6. In Jthe case of .smallinstallationa t s voperation can be easily eiected lby hand .by means of a hantapr nozzle 7, to the interior of the grate los dle and appropriate gearing mounted on the front of the carriage. In the case of large installations, and central stations, the
operation may be effected mechanically and to time, thus communicating a slight oscillation to the fire bars, and in this way the whole surface of the combustible materials will be swept in turn by the air.
In the case of large installations this movement of oscillation can easily be obtained mechanically.
The hollow fire bars may in some cases be1 three cornered, quadrangular or elliptica For effecting complete cleaning,4 or for repairs, the whole of the grate can be drawn out ofthe plant on the wheels or rollers 4. The apparatus may be adapted to any furpzlices orl for heating boilers, ovens or the i. ze.
VVha-t I claim and desire to secure by Letters Patent of the United States of America 1s:-
l.. In a' grate for gas producers, furnaces and the like, the combination of a supporting frame, hollow bars rotatably mounted in said frame and adjacent to one another,
each-bar being provided with a .substantially semi-cylindrical portion extending substantially throughout the entire 'length of the bar, and normally forming the supporting surface of the grate, longitudinal ribs projecting from the surface of lsaid bars opposite the semi-cylindrical portion and extending substantially throughout the length of said bars, and means for rotating adjacent bars in opposite directions;
2. In a grate for gasproduers, furnaces and the like, the combination of a supporting' frame, hollow fire bars rotatably mounted in said frame, the said bars being arranged in pairs, means for rotating the bars in each pair in opposite directions, each bar having an upper fuel supporting surface substantiallysemi-circular in cross section', the lower surfaceof said bars being provided with projecting ribs extending substantially throughout the length of the bars, the ribs on adjacentbars co-operating upon rotation thereof, to 4engage and break the cinders and deliver themto the ashpit. 3. In a grate for gas producers, furnaces and the like, the combination of a supporting frame, hollow fire bars rotatably mounted in said franje, and adjacent to one another, means for rotating said bars, each bar being provided with a semi-cylindrical upper surface normally forming the isupporting surface of the grate, the lower portion of saidybais being provided with projecting ribs extending substantially throughout the length of the bars, the projecting lribs of adjacent bars co-operating to break the cinders and deliver them to the ashpit upon rotation of said bars, the semi-cylindrical portion of the firev bars having radially extending perforations passing therethrough, and means for supplying fluid to the interior of the hollow bars.
4. In a grate for gas producers, furnaces and the like, the combination of a supporting frame, hollow bars rotatably mounted in said frame and adjacent to one another, each bar being provided with a substantially semi-cylindrical portion extending substantially throughout the entire length of the bar, and normally forming the supporting surface of the grate, longitudinal ribs projecting from the'surface of said bars opposite the semi-cylindrical portion and extending substantially throughout the length o f saidvbars, and ymeans for rotating such bars.
In testimony whereof, I have signed myY name to this specification at Paris, France,
May, 1924.'
