Influence of gas flow rate and reactor length on NO removal using pulsed power

A short duration of 100-ns pulsed power has been used to remove nitric oxid e (NO) in a mixture of nitrogen, oxygen, water vapor, and NO, simulating fl ue gases from a power station. The effects of the gas now rate, the reactor length, and the pulse repetition rate on the percentage of NO removal and its energy efficiency are reported. The percentage of NO removal at a fixed gas flow rate increased with increasing pulse repetition rate due to the i ncreased energy into the discharge. At a fixed pulse rate, the removal of N O increased with decreasing gas flow rate due to the increased residence ti me of the gas in the discharge reactor, thus facilitating the creation of i ncreased radicals of O and N which then decreased NO. The energy removal ef ficiency of NO (in mol/kWh) decreased with increasing gas flow rate and inc reasing removal ratio of NO. The removal of NO increased with increasing en ergy density (J/I) input into the discharge at different reactor length.
