The orders include baseline testing, computational fluid dynamic modeling and services for 15 units for five customers in the Midwest and Southeast.

The five customers are evaluating selective non-catalytic reduction (SNCR) technology as an option to comply with their nitrogen oxide (NOx) emission requirements under the Cross-State Air Pollution Rule, which takes effect 1 January 2012.

Fuel Tech chairman, president and CEO Douglas Bailey said the company has been selected by the utility customers to help them evaluate their short term strategies to achieve compliance in a dynamic regulatory environment that is calling for greater reductions in NOx emissions.

"The SNCR technology can provide our customers with timely NOx reductions where boilers may operate across a wide load range, and these flexible systems are designed to compliment additional NOx reduction technologies, including combustion modifications, Advanced Selective Catalytic Reduction (SCR) and conventional SCR," Bailey said.
