The heat accumulative type incinerator system uses the ceramic heat accumulator to store the heat generated from the decomposition of the organic gases and then the accumulative heat in the ceramic heat accumulator is used to treated any untreated organic gases bringing very high heat efficiency. The temperature for oxidation is normally between 810℃ - 980℃. The heat accumulative type incinerator system is mainly applied where the organic gas is in large quantity but in low concentration. The equipment performs the best when the organic gases contain corrosive substances or any elements toxic to the catalyst; this incinerator is also suitable for treatment of certain odors where high temperature is required for oxidation. This incinerator shall not be used in occasions when the temperature of the waste gas is relative high before being discharged or the waste gas flow rate is below .5000 Nm3 / h;
