| Abstract: | A simple apparatus for measuring the efficiency of
sub-nozzle has been developed by checking the air velocity at the nozzle outlet
at the predetermined pressure. The testing set-up can also be used for the
comparison of different types of nozzles, either main or sub-nozzles. It is
observed that sub-nozzle with 19 holes gives less air velocity than that of one
circular hole sub-nozzle. This is because of the possible contamination due to
which the holes of used sub-nozzles get blocked and remain not so smooth, thus
giving less air velocity, and hence the lower efficiency. Based on the above, continuous measuring of
sub-nozzle
efficiency has become a necessity. The design of the suggested apparatus is
simple and reliable. |
