Abstract EN

Modification of Dead space method by find a new values of dead space factor, is called geometrical quenching, depending on a largest dimension of Benson's flames.

An experimental procedure are cried of Premixed Methan, Butan, and Propan have cared the with air mixture at 25Co , 75Co , 100Co , and 125Co of unburned gases temperatures condition have been detected practically for wide range of equivalence ratio by using schlieren's photography method for tube burner.

The effect temperature and equivalence ratio on new factor are studies.

Vertical dead space has been detected, and effect of this dimension has been study.

The burning velocity recalculation by new technique and compares with calculation by CCM, and find the percentage error is less than 10%.
