Summary
NOₓ recycle is one part of the NOXSO process. In this process, 90% of the acid pollutants (NOₓ and SO₂) can be removed simultaneously by adsorption on the surface of a PO sorbent material. The sorbent is subsequently regenerated by heating and contacting the hot sorbent with a reducing gas followed by steam. The NOₓ is removed in the heating process, and the SO₂ is removed by the chemical reaction of the reducing gas and steam. The NO ₓ stream produced is returned to the combustion process with combustion air, which is called the NOₓ recycle. The NOₓ is reduced in the flame to N₂, H₂O, and CO₂. NOₓ recycle will be implemented at the full-scale commercial demonstration plant at Niles. The concept of NOₓ recycle has been tested previously at DOE-Pittsburgh Energy Technology Center (PETC) using a 500 lb/hr coal combustor used for the 3/4 MW tests and also using a tunnel furnace capable of being fired with a variety of fuels including gas, fuel oil, coal, and coal-water mixtures. The results were very promising and demonstrated the destruction of NOₓ compounds when fed to the combustion system. The data also indicate that the extent of NOₓ reduction is determined by the location of the NOₓ injection and the combustor design. This current project is pilot-scale testing of NOₓ destruction mechanisms and to help with the implementation at the Niles station.
