Principal among these was an order for two aqueous ammonia-based selective catalytic reduction systems for nitrogen oxide (NOx) reduction at two municipal solid waste incinerators in Spain. Initial deliveries of equipment and catalyst are scheduled in the current quarter, the company said.

Additional orders were received in the US for computational fluid dynamics modeling for a biomass facility and additional startup services for a previously announced NOx reduction project.

Douglas Bailey, chairman, president and CEO of Fuel Tech, said: “We are pleased to report that the order from Spain represents our largest single contract for a system operating in Europe. The last year and a half has shaped up to be one of our busiest times for our European operation.

“In the MSW market alone, we have received orders for nine NOx control systems, prompted by looming compliance deadlines in a number of European Union nations. Discussions to secure other MSW business is ongoing as are efforts to market our broadened suite of NOx control technologies throughout Europe.”
