The flame itself will get bigger/hotter, and the amount of 'blue' increases. Depending on the type of burner, it may or may not increase proportionately with the total flame size.

You can make the flame hotter by first, lowering the flame from the starting point by slowly closing the gas valve until the flame is at a medium height. Then, you should increase the oxygen intake by slowly opening the oxygen valve until you have a completely non-luminous flame (an all-blue flame), which is hotter than an orange or yellow flame.
