All units are equipped with SCR systems for NO x control. A full-scale test to evaluate the effect of the SCR was performed on Unit 2, a 550 MW T-fired boiler firing a medium sulfur bituminous coal.

At one Northeastern utility, SCR systems have been in place on two cyclone boilers (Unit 1, 120 MW and Unit 2, 320 MW) for four and seven years, respectively. Untreated NO x emissions from the ...

Retrofitting a selective catalytic reduction (SCR) system at any operating plant is a major undertaking, but the retrofit project reaching completion at Tampa Electric’s four-unit Big Bend Power ...

Using a selective catalytic reduction (SCR) system to reduce the emissions of nitrogen oxides (NO x) from a coal-fired power plant is rapidly becoming the norm, rather than the exception.But for ...

The fluid delivery system with dosing control software is capable of managing multiple injection points and sensors. The system can support urea flows up to 120 meters, which enables a wide array ...

The main components of the MAN Diesel & Turbo SCR system are an SCR reactor, catalyst elements, a soot-blowing system, a dosing unit, a mixing device, a urea-injection lance, a control unit and a ...

At the 2014 WorkBoat show, Tenneco introduced a new large engine selective catalytic reduction (SCR) system for marine and large engine applications.

The purpose of this standard is to establish the minimum design requirements for the functional design specifications of selective catalytic reduction control systems for use in fossil fired power ...

The CataStak™ SCR system also incorporates a state-of-the-art NOx reduction control system for precise ammonia flow control. This feed-forward control system ensures compliance is maintained ...

The emission solutions division of Cummins Inc. is rolling out a new aftertreatment system designed to help truck makers comply with the tighter greenhouse-gas standards coming in 2017.

The SCR catalyst is mounted downstream of the DPF to prevent hydrocarbon, ash or soot from entering the system. Because of the design, there is no need for a second diesel oxidation catalyst to be ...
