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 ...

Unit 7, which entered service in 1962, uses a Babcock & Wilcox (B&W) cyclone boiler that produces 160 MW. Unit 8, also using a B&W cyclone boiler, has a net full-load output of 320 MW and was ...

For applications incorporating high-sulfur diesel fuel, Tenneco also offers soot blowers, which can be easily incorporated into the SCR system and integrated with the dosing control unit.

For the bituminous coal – fired units, Hg oxidation by the SCR system ranged from 10% to 71%, while the PRB-fired unit experienced a 10% increase in Hg oxidation.

The compact SCR system is one of four – originally ordered in 2018 and 2019 ... as well as the reactor’s control unit that communicates with the engine-control system. ...

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 ...

DaimlerChrysler, the continent’s biggest diesel engine producer for commercial trucks, says it will use an emission control system that uses selective catalytic reduction, or SCR, on all its trucks, ...

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 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.

Single Module aftertreatment system combines the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems into a single canister. The ...

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