<p>A METHOD AND DEVICE FOR THE FEEDING OF FINELY DIVIDED SOLID MATTER TO A GAS-CONTAINING VESSEL Process and device for introducing solid particles, e.g. particulate coal, into a gas-containing vessel, using a centrifugal coal pump comprising a feed inlet and a rotor. The rotor is surrounded by hydrogen, having a lower density than the vessel gas in order to reduce friction. means to reduce leakage are provided for.</p> |
