Method of restricting dust development when feeding coal into coke ovens. [12 claims]

Patent ·
OSTI ID:7301955
Coal is preheated and contacted with 0.5 to 3 percent by weight of moist coal tar, preferably bituminous coal tar. The thus-treated coal is admitted into a coke oven through the ceiling of the latter. The coal is poured into the coke oven, rather than being blown in, and is permitted to descend into the coke oven under the influence of gravity. Preferably, the coal is poured into the coke oven through at least two or three openings in the ceiling thereof. The coal tar serves to bind finely divided coal particles to the coarser particles and, in this manner, the development of dust during the introduction of the coal into the coke oven is restricted and, concomitantly, the danger of ignition or explosion is reduced. 12 claims, 1 figure.
