Larry Swanson of GE Energy told the participants that an additional 60 percent NOx reduction can be obtained by injecting the biomass as a reburn fuel rather than primary fuel. It takes as little as 15 percent biomass to obtain greater than 50 percent NOx reduction. A fuel flexible process allows injection of either biomass or coal as the reburn fuel. GE is presently looking for a beta site to move to full scale demonstration with this technology. |
