Abstract: PURPOSE: A premixing pure oxygen combustor is provided to prevent thermal damage to the swirler by forming a premixing chamber between the swirler and the combustion chamber. CONSTITUTION: A premixing pure oxygen combustor comprises a fuel supply pipe(110), an oxygen supply pipe(120), a swirler(130), and a premixing chamber(140). The fuel supply pipe includes a fuel inlet(111) on one side and a fuel nozzle(113) on the other. The oxygen supply pipe covers the exterior of the fuel supply pipe, lets oxygen in through an oxygen inlet(121) on one side and supplies oxygen to the fuel discharged through the fuel nozzle. The swirler is installed on the oxygen supply pipe to swirl the oxygen being supplied to the fuel. The premixing chamber transfers a fuel-oxygen mixed gas to a combustion chamber(150).
