US based Fuel Tech, a provider of combustion and emissions control systems, has received air pollution control orders worth $2.3m.

A domestic industrial customer placed the largest order for a NOxOUT Selective Non-Catalytic Reduction (SNCR) project for a biomass-fired boiler, which will be delivered later this year.

The SNCR process is post-combustion reduction method that reduces nitrogen oxide (NOx) through the controlled injection of reagent into the post-combustion flue gas path.

Two orders were received from a Chinese based utility and another from an existing customer.

The utility will receive an ULTRA system for a retrofit coal-fired unit, later this year.

The ULTRA process provides on-site conversion of urea to ammonia for use as a reagent in the selective catalytic reduction of NOx, eliminating the hazards associated with the transport, storage and handling of anhydrous or aqueous ammonia.

The second order consisted of a NOxOUT Selective Non-Catalytic Reduction (SNCR) project for two municipal solid waste combustion units in China.

The equipment will be delivered later in 2011.

Fuel Tech also received orders for two CFD modeling in Korea and the southeast U.S. as well as a spare parts order for a Low NOx Burner project in Indonesia.
