Expected Outcomes of this project are as follows: (1) There are no previous studies on co-firing cattle biomass (CB) and coal in low NOx burners (LNBs) and the subsequent effect it will have on NOx and Hg emissions. It is hypothesized that co-firing cattle biomass along with primary controls can provide more reductions on NOx and Hg than simply firing coal alone in a LNB. Moreover, adding co-firing to a LNB may provide NOx reductions comparable to selective catalytic reduction (SCR) systems, but with the added benefits of Hg and non-renewable CO₂ reductions. (2) LNBs do not have market vulnerability, as they are interchangeable with existing conventional burners, and are rugged and durable with less maintenance cost. (3) Once the proposed technology has been demonstrated, there is the possibility of emission reductions from stored CB and the generation of additional revenue to both farmers and power companies. (4) Moreover, there is the prospect of improving the environment in terms of improved air quality and the sustainability of clean streams and watersheds in rural America. Manure-based biomass can add a significant portion to the list of new, renewable fuels available to the country's power production facilities from a growing, industrialized agricultural sector. (5) If the genetically engineered forage sorghum reduces NOx when cofired with coal, then it alleviates the problem of limited supply of CB for reduction of NOx and leads to a continuous supply of renewable biomass fuels for emission reduction. |
