FREMGANGSMAATE TIL FJERNING AV SLAGGKAKER FRA SYNTESEGASSREAKTORER

摘要

A method for removing slag cakes from synthesizing gas reactors. The seal at the bottom of the reactor is removed, an orifice is melted through the partially solidified slag cake by means of the flame of an oxygen core lance, the liquid slag is drained and the residual parts of the slag cake are liquified by means of an oxygen excess powered gas flame and allowed to drain. When the seal at the bottom of the reactor is in the form of a flat frustum of a cone and made of refractory material filled into a fixed refractory ring the method is facilitated.
