This application belongs to the field of combustion equipment technology, and particularly relates to a combustion device based on nitrogen-oxygen separation. The device includes a combustion unit with at least two oxygen inlet pipes on its outer side. These pipes are connected to a gas supply pipe, and a nitrogen-oxygen separation device is installed on the gas supply pipe. This application utilizes the heat from the exhaust gas discharged from the combustion unit to heat the thermally conductive spacer within the nitrogen-oxygen separation device. Air is then introduced into the thermally conductive inner tube of the nitrogen-oxygen separation device, causing the 5A zeolite molecular sieve within the inner tube to separate oxygen and nitrogen from the air at high temperature. The separated oxygen enters an oxygen storage pipe, allowing high-purity oxygen to be continuously delivered to the combustion unit through the oxygen storage pipe. This significantly reduces the formation of nitrogen oxides within the combustion unit and lowers the cost of oxygen usage.
