REGENERAI R. 1
Application filed January 27,1922] Serial No. 532,192.
To all whom it may concern:
Be it known that I, WALDEMAR DYhssEN, a citizen of the Ignited States, and resident of the city, county, and State of New York, have invented certain new and useful Improvements in Regenerators, of which the following is a specification.
This invention relates to improvements in metallurgical furnaces and particularly to the arrangement of the regenerative cham-' berstherefor whereby means are provided for trapping or catching the greater part of the dust particles carried in suspension by the exhaust gases from an open hearth furnace. a One embodiment of the invention is illustrated in the accompanying drawings in which .Fig. 1 is a horizontal section through an open hearth furnace showing the ,regenertotal-,volume of such former'regenerators" is g eater than that required to preheat the ators. in top plan; a
Fig. 2 is a similar view in horizontal sect-ion'taken on a lower plane showing the regeneratois, the slag pocket and the dust separating passage.
checker-work is omitted from the regenerator on the right side to show the supporting girders therefor;
Fig. 3 is a vertical section through the dust separating-passage,theslag pocket and the up-take at one end of the furnace -the section being taken on the line 3-3 of Fig. 4 is a vertical section'thr ough one end of the furnace on the line 44 of Fig 1;
Fig. 5 is asection on theline 55 of Fig. 2 showing the regenerators and the dust separating passage.
Referring to the embodiment illustrated,
the furnace 10 comprises'the usual hearth 12, roof 14 anda combustion or mixingchamber 16 which is connected by suitable fuel used is preferably'pulve rized coal, tar.. or by-product coke oven gas, oil or any other fuel which does not require preheating.
Heretofore furnaces using producer gas-and other gases of low thermal value have preheated the gas in special regenerative chambers so .as to promote their efiicient combuss tion within the furnace.
VVhen'using fuels such as above mentioned,v
' which do not require preheating, it is un- In 1 this view the,
parate necessary-toutilize such a great area for the regenerative chambers. Heretofore it has been almost'universal practice to useregenerators for both gas and air, but: the present day practice leans toward the use of fuels not requiring preheating. One of the difiiculties with such fuels, however, is that they introduce a considerable quantity of dust into the furnace and this is particularly true when using pulverized coal.
My invent-ion aims to provide means whereby thisdust can be effectively separat-v ed from the exhaust gases so that it will not enter the regenerators and clog up the checker-work therein. In order to use pulverized fuel for existing furnaces it'is only necessary to provide a suitable fuel inlet and alter the regenerators so that the chambers formerly used for preheating the fuel can be used for preheating the air. The
r alone. :QTherefore, the space in such reeiierator can readily be utilized for trapi'ng-the dust carried in suspene exhaust gas,
d' by, a'central passage 30,the opposedlwalls 32- andv '34'which are provided withiports 36 and 38 communicating with the - regenerators 26 and 28 respectively.
,The dust separating chamber'is connected with the slag pocket20 by a port 40'having inclined top andbottom walls as shown in Fig. 3. At one end the dust separating chamber 30 is closed by a thin wall 42 built in ga doorway 44 which is adapted tobe removed to. permit the cleaning out of the accumulateddust in the passage 30.
" In operation the pulverized fuel entering through the burner 24 meets the heated air which has passed through the regenerators,
While I have described with great par- -tieularity the details of the embodiment shown, it is not-to be construed that I am limited thereto, as changes in arrangement.
and modifications may be made by those skilledin the art without departing from. the invention as defined in the appended claims.
What I claim is: v 1. A. regenerative metallurgical furnace adapted to heat the air but not the fuel for combustion, having an uptake at the lower .end .of which is a .slag pocket, and having a pair of regenerators alongside of each other with a dust separating passage between them, and having a bridge wall at the side of the slag pocket toward said dust separating passage.
2. regenerative metallurigal furnace adaptedto'heat the air but not the fuel for combustion, having an uptake-at the lower end of which is a slag pocket, and having a pair of regeneratons alongside of each other with a dust separating passage betweenthem, and a passageway between the slag pocket and the dust separating passage leading downward to the latter.
3. A regenerative metallurgical furnace adapted to heat the air but not the fuel for combustion, having an, uptake at the lower end of which is a slag pocket, and having a pair of regenerators alongside of each other with a dust separating passage between them, and a passageway between the slag pocket and the dust separating passage leading downward to the latter, the side walls of said dust separating passage having ports near the top for the admission of the gases to the regenerators after the removal of the dust in said passage.
4:- In a metallurgical furnace a pair of regenerators for heating the air, the opposed Walls of said regenerators forming a central passage extending the full length and full height of the regenerators, and ports in said walls communicaing with said regene'rators.
In witness whereof, 1'. signed my name.
