Numerical calculation was performed to obtain extinction limits of counterflow diffusion flames for blended fuels of CO/H_2 and CO/CH_4,which are produced by thermal decomposition in incinerators. The computer code PRIMIX was converted into a calculation program for counterflow flames, and GRI-Mech ver.2.11 was used as a chemical scheme, eliminating reactions of N and including the radiation heat loss. The stretch rate at extinction of the blended fuel CO/CH_4 has a maximum at a certain mixture ratio as has been shown in the burning velocity. The effects of diluents such as CO_2 and H_2O were also calculated because blended fuels are always diluted by those inert diluents, showing that the stretch rate at extinction has a maximum at a certain dilution rate as well as the mixture ratio of fuels.
