BLUSTOREN VOOR HET NATBLUSSEN VAN COKES, VOORZIEN VAN EEN UIT EEN BUIZENROOSTER BESTAAND WATERSPROEISYSTEEM.

摘要

For increased efficiency of coke quenching, the quenching water is supplied to the surface of the hot coke being quenched in the form of essentially vertically directed solid jets of substantial diameter (as distinguished from the conventional fine spray). These solid jets are preferably provided by a multiplicity of syphon tubes operating under very little hydrostatic head. In the illustrated embodiment the syphon tubes may have inside diameters of about 17 mm, and mouth opening diameters of about 14 mm located about 1.5 meters above the coke surface and spaced about 20 cm, substantially uniformly above the entire surface of the coke bed. The arrangement improves the uniformity and efficiency of quenching by reducing deflection, carry-over and evaporation of quenching water by the rising steam in the region above the coke bed and assures a more uniform distribution of water over the mass of coke, so that more of the water reaches and is uniformly distributed on the coke bed to be vaporized in contact therewith.
