Urea solution is stored in a tank constituted by a cylindrical vertical vessel made of FRP (Fiber Reinforced Polymers), equipped with connection pipes for reagent loading. The tank capacity is of 20 m3, sufficient for approx. 10 days of the SCR system operation with plant at nominal load (MCR) and reference pollutants concentrations
From the tank, the reagent is extracted by means of a pumping station and supplied to the metering module that doses it in the post-combustion chamber, according to the process requirements.
Two 100% volumetric pumps are foreseen (1 in operation + 1 in stand-by), coupled to the respective electric drive on a single common base.
