Description
roKUsABUao saro, or os'arrn, JAPAN.
COKE ovmv.
VApplication 1ed`0ctober-26, V1920. Serial No. 419,765.
To all whom it may Concern.'
Be it known that I, ToKUsABUno Saro, a subject of the Emperor of Japan, and a resident of No. 1061, Tamade-Machi, Nishinari- Gun, Osaka, Empire of Japan, have invented a new and useful Improvement in Coke Ovens, of which the following is a specification.
This invention relates to improvements in lcoke-ovens and means for supplying air thereto, and refers particularly to means for supplying air to coke-ovens of the type in which a supply of air is led into the oven, at a convenient point between the grate and the outlet flues through a series of apertures or perforations by which the air is distributed evenly through the gases. The air is preferably initially heated by passing through fines, surroundingxthe oven.
The object of this invention is to provide a simple and improved air-supply means of this type, which is simple to manufacture, is efficient in operation, and effects a very thorough distribution of the air. The invention essentially comprises a hollow'air-dis- Y tributing box or chamber, formedk of firebrick or like fire-resisting material, and having a series of perforations in one face communicating with the hollow interior to which air, preferably under pressure, is supplied. y
This air-distributing means located at a suitable point in the oven, and causes the air supply to be evenly distributed through the gaseous products of combustion to ensure the complete combustion thereof.
Suitable means are provided enabling the supply of air to be varied to control the combustion.
In the accompanying drawings Fig. 1 is a vertical longitudinal sectional view.
Fig. 2 is a horizontal sectional view of the same.
With reference to thefiguresof the drawing, the air Yspraying device is made of any suitable refractory material and has a plurality of staggered or honey-comb like perforations 2 in its front part, and an air chamber 3 formed in the body of the device communicates with the atmosphere or with a supply of air under pressure.
The grouping` of the perforations above referred to is one feature of this invention. The velocity of the air spray passing through these perforations should be considerable on Vaccount of the very narrow passages, and
in fact is so high that the air spray will cut the fiame transversely instead of flowing along theV line of flame, so that any gaseous matter left unburnt in an oven is bound to come in contact with these high speed sprays of heated air, and the result is the complete combustion of the fuel. The amount of hot air supplied is controlled by means of a regulating door fitted at the entrance of the air chamber, or other suitable means.
rIhe efficiency of a coke oven, can be considerably increased by the use of this device.
Four of the air distributing devices are shown located in the walls of the oven, chamber 16, two being located at the sides of the end wall remote from the outlet flues, andV twobeinglocated in the side walls. Air is supplied through regulating valves 4, of any suitable type, and passages 5 in the walls of the oven, the air being heated as it passes through these passages and being distributed from the chambers 3 through the perforations 2.
The perforations 2 are preferably inclined towards the outlet fiues, as shown in the.
drawings, so that the air emerging from the perforations assists the natural draught in the oven, and the air is thoroughly distributed through and mixed with the gases generated in the chamber 16, so that the combustion of the gasesris rendered *com-k plete. 16 bythe fiue or fiues 17 and is led along through the walls of the oven before reaching the discharge chamber 18.
What I claim is A coke oven having air inlet ducts in one of its walls and also having air distributing chambers on the inner side of said wall and to which the said ducts respectively lead, one of said chambers being arranged in one front corner of the oven and having a wall arranged diagonally in said corner and prg- The burnt gases leave the chamber wall, said chamberalso having anoutlet flueV provided with an intake toward which the said openings of said air chambers are directed.
In testimony whereof I aix my signature in presence of two witnesses.
TOKUSABURO SATO. Witnesses:
