EGTEI- Emerging Technologies sub-Group Current Status of Work Ia Emerging Abatement Techniques 1- Sox-Nox-Rox Box (SNRB) 2- Limestone Injection Multistage Burner (LIMB) Ib Emerging Abatement Technologies 1- Catalytic Combustion
Ia/ SOx-NOx-Rox BOx (SNRB TM) • Technology • SOx-NOx-Rox Box™ (SNRB™) process • (Babcock & Wilcox) • Pollutants • SO2 , NOx and particulates • Process description • Process that combines hydrated lime • and ammonia injection upstream of hot • catalytic baghouse (box) where the solid • product calcium sulphite and sulphate • and particulate (Rox) are removed, and • the NOx is reduced to nitrogen and water . • Implementation experience • Location • Dilles Bottom, Belmont County, OH (Ohio • Edison Company's R.E. Burger Plant, Unit No. 5) • Year/ Scale • 1995 / Pilot • Capacity/Production • 5-MWel • Coal : • Bituminous coal blend, 3.7% S
Ia/ SOx-NOx-ROx BOx (SNRB TM) No information is available wether this process is actually applied to a large combustion plant. Therefore, no information on the general performance of the SNRB process can be given
Ib/ Limestone Injection Multistage Burner (LIMB) • Technology limestone injection multistage burner (LIMB) system(Babcock & Wilcox) • Pollutants • SO2 • Process description • Injection of a sorbent (limestone) within certain windows, within a boiler‘s time temperature prrofile. • Implementation experience • Location • Lorain, Lorain County, OH (Ohio Edison's Edgewater Station, Unit No. 4) • Year/ Scale • 1992/ full-scale • Capacity/Production • 105 MWel • Coal : • Ohio bituminous, 1.6, 3.0, and 3.8% S
Ib/ Catalytic combustion • Technology that combusts fuel flamelessly • Pilot scale 1.5 MWel gas turbine • Plants for application on a 170 MWel gas turbine are being developed • Nox levels of less than 10 mg/Nm3 are expected
