summon FOR enanunan FUEL SUCH as THE COKE ansrnun on THE DIS-TILLATION or Biz-own coat.
Application filed October 4, 1923.
T 0 all whom it may concern:
Be it known that I, CLEMENs DtiLLMANN, a citizen of Germany, residing at Liebert wolkwitz, near Leipzig, Germany, have in vented certain new and useful Improvements in Furnaces for Granular Fuel Such as the Coke Residue of the Distillation of Brown Coal (for which I have filed appli cation in Germany October 29, 192i, No. D 40,609, V/36 of which the following is a specification.
My invention relates to improvements in furnaces for granular fuel, such as the coke residue from the distillation of brown coal, and more particularly in furnaces in which the fire place comprises a plurality of spaced sections disposed one above the other. The object of the improvements is to provide a furnace of this type in which the fuel placed on the upper section or sections is more readily kindled and the fire is ,readily spread over the coarse particles of the fuel. With this object in view, 1 construct the subsidiary sections which are located above the main section of undulated form in crosssection, the upper section being formed at the top of the undulations with comparatively large passages through which the coarsest particles of fuel may not pass but. permitting the passage of the fine and medium sized particles therethrough, while the main part is formed with narrow passages permitting only the fine particles of fuel to pass through the same.
For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in which the same reference characters have been used in all the views to indicate corresponding parts. In said drawing,
Fig. 1, is a part sectional elevation of a furnace embodying the invention,
Fig. 2, is a section of the fireplace on an enlarged scale, and
Fig. 3, is a partial plan view of Fig.
In the example shown in the drawing the fire place of the furnace f comprises a main section a in the form of a box and two subsidiary sections 7) and 0 located above the main section and made from foraminated e of sheet metal.
Serial No. 866,586.
sheet metal. or in the form of sieves. To hold the subsidiary sections the proper distance apart I prefer to mount the same in a frame The section b is preferably provided with steep undulations and the section with shallow ones. The forainlntltlOllS of both sections are substantially alike, but the section 0 is formed at the crests of the waves with broad slit-s d.
When charging the upper section with granular fuel, such as the coke residue from the distillation of brown coal, the finest particles of the fuel fall through the small holes of the section 0 upon the section b, and a part of the fuel of medium size falls through the slots (Z of said section. Therefore on the lower section b alternating strips of fuel of different grades are deposited, one beside the other. A similar distribution of the fuel is made on the upper section 0, the depressed portions of the waves containing the strips of medium sized and coarse fuel, while above the slits (i there is only coarse fuel. Such separation is produced on the upper section 0, because the coarse and medium sized fuel cannot pass through the narrow passages in the depressed parts of the waves, while the broad slits d at the crests of the waves permit the passage therethrough of the medium sized particles and hold back only the coarse fuel.
I have found that. by thus separating the fuel into strips of fine and coarsefuel, the fire is more readily kindled, because the strips of fine fuel are readily kindled and the fine fuel, after being ignited, starts igniiic-n of the coarse fuel in contact therewith. Furthermore, heating is made etfective because the coarse particles, which ordinarily are not readily burnt and which in my furnace are placed above the broad slits (Z receive a strong supply of air through the said broad passages.
By constructing the upper section 0 with shallow waves the finer particles of fuel pass more readily through the holes of the said section upon the lower section b, and they are held back on the lower section because the walls containing similar holes as the walls of the upper section are comparatively steep and provide a reduced passage in vertical direction.
The frame 6 is either slidably mounted in the furnace or fixed thereto.
While in describing the invention reference has been made to a particular example embodying the same I Wish it to be understood that my invention is not limited to the constructionshown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
I claim:
1. A fireplace for granular fuel, comprising a main fuel supporting member and subsidiary members located above the same and one above the other and spaced from each other, the subsidiary members being Wave like in cross-section and formed with passages permitting the fuel to fall through the same, the upper subsidiary member be ing formed at the crests of its Waves with enlarged passages.
2. A fireplace for granular fuel. comprising a main fuel supporting member and subsidiary members located above the same and one above the other and spaced from each other, the subsidiary members being wave like in cross-section and formed with passages permitting the fuel to fall through the same, the upper subsidiary member being formed at the crests of itswaves with enlarged passages and having its waves shallower than the lower subsidiary member.
23. A fireplace for granular fuel, comprising a main fuel supporting member and subsidiary members located above the same and one abo've the other in spaced relation, the subsidiary members being wave like in cross-section and formed with. passages permitting the fuel to fall through the same, and a common frame in which said subsidiary members are mounted, the upper sub sidiary member having enlarged passages at the crests of its Waves.
In testimony whereof I have afiixed my signature.
