Finite-rate mixing effects n reuring

摘要

Applicaiton of natural ga sreburning for NO_x ocntrl involves the injection fo fuel jets into hte furnace cavity.In the region near the jets both mixin and reaction occur simultaneously,leading to the obsdrvaiton that finite-rate turbulent mixing strongly influnces chemical NO_x reduction.in this paer,the effect of finite-rate mixing on reburn performance is inverstigated u8sifng a simplified integal modle of a turbulent,kreacing jet (based oon th Two-Stae Lagrangian model of Broadwell and Lutz).Various sets of mixing influenced re burning data from Koolb et al.
