Burner pipes burner pipes are used to convey and introduce fuels into the pyroprocess fuel is conveyed pneumatically through the inside of the burner pipe and blown into the kiln where it ignites providing the necessary heat for the process the process environment is subject to thermal shock the result of a sudden loss of flame alkali attack alkali from the fuels and severe abrasion from dust

In rotary kilns irrespective of the fuel used the most obvious common feature of the firing system is the firing pipe burner pipe which passes through the kiln hood at the kilns hot end arranged more or less along the kilns centre line and through which the fuel is projected into the kiln at high velocity the effect is rather like a bunsen burner producing a flame that extends some way up the kiln

The burner in a rotary kiln functions as an injector the purpose of which is to draw the secondary air coming from the cooler into the flame in order to make the fuel burn as close as possible to the centre line of the kiln this explains why the momentum of the burner is the parameter that determines flame formation a higher
