Fuel Tech Inc. (NASDAQ: FTEK) received $3 million in emissions control orders.

The largest of the orders was for the retrofit of two coal-fired units at an unnamed power plant in China. The retrofits include Fuel Tech’s Ultra systems that converts urea to ammonia for use as a reagent in the selective catalytic reduction of nitrogen oxide (NOx).

Fuel Tech also signed a contract to deliver selective non-catalytic reduction systems to three combustion units at an unnamed power plant in the U.S. The systems are expected to address NOx emissions requirements under the Cross-State Air Pollution Rule. Both deliveries are expected to begin in late 2011.
