Wegeners Apparatus for Burning Powdered Fuel. The accompanying engraving, reproduced from the Engineer, il-lustrate a new form of apparatus designed by Herr Wegener forburning finely pulverized coal, and burning it in such a way thatthe quantity is automatically varied with the quantity of air ad-mitted for supporting combustion. The apparatus has been in usesome time in Europe, and is now in use in the works of Donkin and Co., London, England. Our engraving shows the apparatus in detail as applicable (o anyboiler. The small sacks of powdered coal, weighing about .50 pounds AND RAILROAD JOURNAL 139 pondertdCoal. The Wegener Powdered Fuel Apparatus for Boilers. are put into a conical hopper ,4: The powdered coal gradually lallsout of the sacks as required into the hopper, aud then on to a sieve-B, about 5}.{ inches diameter, with small openings in it. Thepowdered coal would not continue to pass through this sieve withcertainty without continual tapping, and this is done in the follow,ing way: Immediately beneath the hopper, and level with the boiler-housefloor, is an air pipe E, about 20 inches diameter, through whichnearly all the air for combustion enters. As it enters it is made topass through the blades of an air-wheel or turbine C, and this passage of the air causes the latter to revolve like a smoke-jack. Onthe axis of this air-wheel there is a little knocker which taps thesieve from 150 to 250 times per minute, causing the powdered coalto descend vertically through the sieve, meeting the air for com-bustion as it ascends vertically.
