Description:
Controlling emissions of nitrogen oxides from stationary sources is one of the primary environmental challenges facing the United States. As a means of meeting this challenge, Energy and Environmental Research Corporation (EER) has devised an innovative technique for using inexpensive, readily available additives in conjunction with the reburning process to provide high-level NOx control. Initial technology development work has been completed in a Phase I program. Activities included researching potential additives, conducting combustion experiments, beginning development of a process model to characterize the technology, and evaluating the technical and economic merits of the process. These activities successfully demonstrated that the promoted reburning process can economically provide high-level NOx control. NOx reduction efficiencies of greater than 80 percent were achieved. The incremental improvement in NOx reduction provided by the promoters was as high as 23 percent. The technology now is poised for Phase II development work that will provide the design, operation, performance, and economic data required to demonstrate the process at full scale.The development work being performed in Phases I and II will demonstrate the technical feasibility of the proposed NOx control concept, provide process data that will allow development of an engineering design for a full-scale application, and assess the economic feasibility of the process. The technology can be applied to new or existing utility and industrial boilers. It is capable of providing high-level NOx control while retaining the cost-effectiveness of gas reburning and not generating any toxic byproducts. Success of the Phase I and II efforts will lead directly to full-scale application on a utility or industrial coal-fired boiler.
