shows the experimental facility under operation.
Detailed investigations on exhaust emissions and visible emissions were per-
formed for all the experimental investigations reported here. The concentration of
NO was measured using a NO
NO
x
chemiluminescent gas analyzer; CO concen-
tration was measured using the non-dispersive infrared method, and O
2
concen-
tration (used to correct the NO and CO emissions at standard 15 % O
2
concentration) was measured using the galvanic cell method. The emission readings
