PURPOSE : A re-burning apparatus having an oxygen separation module including the oxygen separate module can setting a combustion condition for maximizing reduction efficiency NOx(Nitrogen Oxide) in re-burning region.CONSTITUTION : A re-burning apparatus(100) having an oxygen separation module comprises : a combustion furnace(110), a fuel supply module(120), an air supply module(130), an oxygen separation module(150) The combustion furnace is classified a primary combustion zone, a reburn zone, and a burnout zone. The fuel supply module supplies a fuel to the primary combustion zone and the reburn zone. The air supply module supplies the air to the primary combustion zone. The oxygen separation module is connected to a heat exchanger(140). The oxygen separate module divides selectively oxygen among an air preheated within a pre-set temperature range. A nitrogen excess air of which oxygen partial pressure is lowered through the oxygen separation module supplies to one among a combustion finish region and specific process.COPYRIGHT KIPO 2011
