    an ignition part integrally formed at the rear end of the reactor so as to ignite a combustible gas partially mixed with the effluent gas from the reactor and the exhaust gas flowing between the reactor and the housing;

    a nozzle mounted at the rear end of the ignition part to be provided with a fuel from a second fuel preheating line, spary the fuel to the exhaust gas and combust the exhaust gas secondarily; and

    a mixer mounted at the rear end of the catalyst reactor for mixing the combustible gas by way of the combustible catalyst and the exhaust gas flowing between the catalyst reactor and the housing.
