A catalytic-flame combustor without backfire is provided to prevent backfire by supplying fuel during catalytic combustion and flame combustion in two stages. A catalytic-flame combustor without backfire comprises a first mixing part(130), a catalytic combustion part(150), a second mixing part(170) and a flame combustion part(190). The first mixing part mixes a first fuel with air. The catalytic combustion part burns a first mixture, which is obtained by mixing air with the first fuel, using catalyst. The second mixing part mixes a second fuel with exhaust gas, which is generated by combustion of the first mixture. The flame combustion part burns a second mixture, which is obtained by mixing the exhaust gas with the second fuel, using flame.
