At least four different systems seem to be g^lving promisingand, we may say, satisfactory results. Of these the Wegenerprocess has made considerable headway in Germany and InKngland. This process was described and Illustrated In in .July, 189G. The results of trials made on a Cornishlioiler by Mr. Ijryan Donkln at that time are reproduced In theaccompanying table. In the Wegener process the powdered coal is delivered tothe feeder in sacks. The fire doors and ash pit openings atthe front of the boiler are closed and the natural draft oftTe chimney is used to deliver the coal dust to the furnacethrough a large duct, over which the dust hopper is the duct is an air turbine driven by the natural air Fig. 3. and this operates a revolving sieve and a tapper whereby thedust is shaken down into the stream of air, by which it iscarried into the furnace. The results of the trials indicatea decided superiority of the dust fuel over the same coalburned upon a grate a few days before in the same extraordinary performance is claimed for the Wegenerprocess, but this test would indicate that its commercial ad-vantages depend largely upon the cost of powdering the far as smoke is concerned, it is perfectly satisfactory. Another German process, the Schwarzkopf!, is particularlyinteresting just now, because of experiments which are beingconducted with it by Mr. Wm. Renshaw, Superintendent ofMachinery of the Illinois Central, upon one of the furnacesat the 14th Street Power House of that road in Chicago. Theplan of this device is shown in the accompanying 1.
