Background technology
At present, station boiler start and low-load combustion-stabilizing during, it is necessary to consume substantial amounts of fuel oil, plasmaassisted
Firing technique can solve igniting and the stable combustion problem of high-volatile coal, save cost caused by fuel oil.Existing document
Actually show that, for low-volatite coal, plasma-ignition technique is difficult to light, and causes plasma-ignition technique to exist with industry
It is difficult to widely use in the unburnable coals such as anthracite, meanwhile, use air as reaction gas, the N in air2After plasmarized
Easily it is oxidized to nitrogen oxides (NOx), add NOxGrowing amount, be unfavorable for the low nitrogen emission reduction of boiler.In patent
Using pure oxygen in arc-plasma in CN201010577320, although pure oxygen can solve plasma reaction gas and be free of
N2The problem of, but pure oxygen price compare come it is expensive, and fundamentally without solving other approach generation NOxProblem.This patent uses
Be the method for supplementing water vapour, can be solved by the special property of plasma state water vapour and the position being passed through and ratio
NOxThe problem of growing amount is high.Meanwhile research of the invention shows, plasma state water vapour is for low volatiles such as anthracites
