TECHNOLOGY
A wet type system using limenstone as absorbent substance and from this resulting gypsum, as a by-product of the retention of sulphur dioxide, which can be used as raw material in cement plants.
IMPACT
Reducing the concentration of suphur dioxides from 6000 mg/Ncm below the limit accepted by the current standards, i.e. below 200 mg/Ncm.
DeNox FACILITIES IMPLEMENTATION PROJECTS
SLAG AND ASH DISCHARGE USING DENSE SLURRY TECHNOLOGY
CURRENT STATUS
Rovinari
–Power Units No. 3, 4, 5, 6 facility in operation since 2010
Turceni
–Power Units No. 3 facility in operation since 2013
–Power Units No. 4 facility in operation since 2013
–Power Units No. 5 facility in operation since 2013
–Power Units No. 7 facility in operation since 2016
Isalnita
–Power Units No. 7 facility in operation since 2010
–Power Units No. 8 facility in operation since 2010
TECHNOLOGY
Slag and ash discharge in self-hardening dense slurry is achieved by a maximum optimal ratio of liquid-solid mixture = 1/1.
IMPACT
Increase in the stability coefficient of the deposit.
Ash is fixed and is not blown by the wind.
The infiltration water is clean and very low in quantity.
OTHER ACHIEVEMENTS DURING JUNE 2012 – DECEMBER 2017
