ETEC IFGR System Costs

PFD Download IFGR Cost-Effective Analysis

ETEC IFGR technology is a very cost effective application of FGR due to elimination of auxiliary FGR fan and combustion air duct modification requirements for proper mixing of the flue gas with the combustion air. The cost of IFGR is a small fraction of the cost of other available NOx control technology systems, i.e., LNB, WFGR. The actual cost, however, depends on unit and site specific considerations that must be defined on a case by case basis.

ETEC's IFGR solution is one of the most cost effective ways to reduce NOx output in combination with additional NOx Modifications and can often undercut the pricing of other companies' solutions by millions of dollars.  Contact us for an evaluation of your NOx reduction requirements and we will provide you with the most comprehensive and cost-effecive method for achieving your NOx reduction goals.

a = Not cost effective. Compliance can be achieved by other cost-effective alternatives.

b = Combustion modifications alone may not be sufficient to meet compliance

 

Note: Cost estimates are highly variable, and accurate estimates can only be made on a case-by-case basis.
