ACO moisture measurement for biomass like wood chips, sawdust and wood shavings Properties: Ideal material conditions for the on-line moisture measurement Flexible mounting of the bypass screw conveyor Maintenance flap for taking samples Subsequently applicable Great experience in the field of saw dust Versions: Length, height, dimensions of flanges on customer requirements Version for explosion-risk areas (EX) The SFM4 bypass screw compaction unit has to be placed in a free fall situation of material, e.g. in a drop shaft. A partial flow of this material is trapped in the first section of the compaction unit. The screw compactor compresses the material and conveys it into the second part of the unit, right across the installed ACO moisture sensor for the determination of the residual moisture. Then the material falls down through a drop pipe back into the process. Based on this constant and equal conditions (density, dumping height, etc...) precise measuring results are available.

based on a moisture measuring system from ACO E.ON „MPP3“ coal fired power plant in Rotterdam-Maasvlakte The “MPP3” is the most modern and biggest hard coal fired power plant with the notable gross power rating of net 1070 MW and a net efficiency of over 46%. The “MPP3” wants to reduce the effects on the environment as much as possible. One point to reach an environmental friendly process is the optimisation of the exhaust-desulphurisation unit. The desulphurisation is made by a wet flue gas cleaning unit controlled by a moisture measurement. This flue gas desulphurisation (FGD) is far more effective than in other traditional coal fired power plants. Beyond the “MPP3” can reach a biomass-combustion up to 30%. Of course the district heating is used from the adjacent companies. General description of the process The desulphurisation is based on burnt lime (CaO) thereby the end product gypsum (calciumsulfad-dihydrat) arises. For the analysis of the produced gypsum there is an in-house
