QUANTITATIVE EVALUATION METHOD OF COLLIDING FORCE OF SPRAY AND EVALUATION METHOD OF DESCALING CAPACITY OF SPRAY NOZZLE USING PARAFFIN

摘要

PROBLEM TO BE SOLVED: To provide a method by which the colliding force of a spray from a spray nozzle and the descaling capacity of the spray nozzle are accurately evaluated even in the case that a material to be treated is being conveyed or that the colliding time of the spray is extremely short.;SOLUTION: The colliding force of the spray from the spray nozzle is evaluated from the change of the weight of paraffin before and after jetting high-pressure spay water by eroding the paraffin by jetting the high-pressure spray water from the spray nozzle installed above the conveyance face while conveying a plate-like paraffin in the horizontal direction.;COPYRIGHT: (C)2005,JPO&NCIPI
