PURPOSE: An exhaust system of a burning apparatus for manufacturing cathode active material for lithium secondary batteries is provided to enhance reactive rate of the cathode active materials while reducing heat loss by easily exhausting gas inside the burning apparatus through an exhaust duct. CONSTITUTION: An exhaust system of a burning apparatus for manufacturing cathode active material for lithium secondary batteries comprises a kiln, an exhaust duct, an exhaust fan (280), an exhaust induction pipe (210), an air hole, an air induction pipe (230), and a pipe connecting device (212). The kiln forms a reaction space. The exhaust duct is equipped in the lower side of the reaction space and samples gas produced after plasticity. The exhaust fan transfers gas sampled inside the exhaust duct to the outside. A ventilation guiding tube forms an exhaust path of gas sampled in the exhaust duct. An external air hole is formed in the kiln and external air is inflowed. An external air guiding tube supplies the external air to the inside the reaction space. The external air joins in the gas exhausted through the exhaust duct. A pipe connecting device connects the external air guiding tube, the ventilation guide tube and the exhaust fan. |
