Question

The ratio of air required for complete combustion of carbon to carbon-dioxide as compared to that re-
quired for combustion to carbon-monoxide is
(a) 1.5 : 1
(6) 2:1
(c) 2.3:1
(d) 3.0 : 1
(e) 3.3:1.​

Answer 1

Answer:

The main combustion products of burning of fuels are carbon dioxide ... Air required per kg carbon = 4.32× (C × 2.667 + (H×8- O) + S) ... As the volume ratio of air: oxygen is 1: 0.21.
