PLASMA DENITRIFICATION METHOD FOR WASTE GAS IN MEDIUM OR SMALL-SIZED BOILER

摘要

A plasma denitrification method for a waste gas in a medium or small-sized boiler. A NO-containing waste gas and a reducing gas are simultaneously added into a plasma reactor, so as to perform denitrification by using a reduction method. Nitrogen oxide in a boiler waste gas can be processed in a normal temperature, without requiring an extra heating system. The denitrification rate is higher than 90%, operations are simple, and running costs are low.
