The E.ON “MPP3” is the most modern and biggest hard coal fired power plant in Rotterdam-Maasvlakte/Netherlands with the notable gross power rating of net 1070 MW and a net efficiency of over 46 % (Fig. 1). The plant produces steam with very high conditions (285 bar, 600-620 ˚C) by using pulverized coal. The steam is converted to power by a turbine and a generator. The “MPP3” is intended to reduce the effects on the environment as much as possible.

One step to achieve the environmentally friendly process is the optimisation of the flue gas desulphurization (FGD) unit. The desulphurization is...
