Section lgPublic Law 6 90; Augusti8i1946 Patent expires J anuary zfi; -1960 Thepresent invention-relates"toimprovements in; charging devices'for combustion" plants-such as gasproducers', kilns-and thelike-of the type in which a distributor is' provided: adj acent the inlet opening from; aichargeichamber.
Charging devices" for' this purpose gare 'usually provided with three or moreseparate'ichutes spaced evenly from one another and symmetri- ,,cally disposed relatively 'to a' centralchute or opening. j It is an object of the present invention to provide a construction whereby the position of the chutes relatively. to the'upper level of the charge in the kiln may be adjusted.
"The invention is further described-with ref- .erence to the accompanying drawings inrwhi'ch:
Figure 1 is a sectionalelevationof-onef form of construction,"the head of the gas'producer 7 being shown diagrammatically,
(Figure 2' is a corresponding plan view. The'inventionwill be more particularly described with reference to a gas ,producerpbut a .distributor :according to'the presentinvention or more can be used as desired,vwh'ich chutes l,
are preferably closed, that is to say are :preferably in the form of tubes orconduits as distinct from open channels, and lead outwardly from a central distributing cone or plate 2 to the outer l; periphery of the kiln or gas producer,:being also lsymmetrically disposed relatively to one; another and 1 to a central opening which may be shrouded by a chute central 4 of truncated form.
The conical plate2 which receives theburden may conveniently be made detachable, so that it may be renewed when worn.
The whole distributorgarrangement l, 2, 3, 4,
-.is amounted. upon, a. cylindrical or other a hollow element 5 carried by three or more rods 6 by which it can be adjusted relatively to the top of the gas producer 1, which producer may be provided in known manner with a water jacket 8 serving for the raising of steam useful in the process of gas manufacture in the gas producer.
It will be seen that, due to the castellated form of the distributor, spaces 9 are provided intermediate the chutes I, so that the level of the burden within the gas producer can be examined therebetween, and poke rods can be inserted at these places by which the level of the fuel bed or the: like:within-= the producer -can be -more accuratelyestimated.
It will be appreciated that 'by this invention lumps of fuel or other material charged to the producer or' kiln, -as the=casemaybe,--and of differing density or size, will= be --more evenly dis- "tributed over the -area -of the kiln, and further that the average depth' of I the :bed: of material within-the kilnwill be more nearlyapproximate to-its minim-um and =maximum depth, whereby -steam= raising within the jaeket -B-=will be maintained -more constant thanhas hitherto i been possible; and also-the f-uel -bed within the kiln or producer ismaintainedmore constant; sothat the gas outlet temperature will =-also-'-'be A main- ".tainedmore uniform.
*In -use the-base of -thefdistributor-will lie in contact with the bed ofnaterial-within the kiln and it is-desir-able that material beifed from* the charging valve I01 in-;sucha manner" that some f ue1;'alw,ays lies in'the: lower" ends, ofthe "chutes I and 4.
1 1These chutes :may :be "maintained rigidly in position by stiffeners; or ties I 2; as shown in Fig- The chutes may also be provided outlets I l. so thatgas. derived fromthe fuel immediately ,belowrv thepchutes-may. .pass, out. tolithe gas, outlet ;;thl1S rendering the .whole. of .lthe-ifuelpbed effective.
