There are three zones in flame, viz. outer zone, middle zone and inner zone.
Outer Zone: This zone is blue in colour. It is the hottest part of the flame, because complete combustion takes place in this zone.
Middle Zone: This zone is yellow and orange in colour. This zone is moderately hot because partial combustion takes place in this zone.
Inner Zone: This zone is dark in colour. This is the coolest part of the flame because no combustion takes place in this zone.
