Abstract

The present invention relates to an improved lining for a reactor for the sub-stoichiometric gasification of waste liquor or black liquor formed in the manufacture of chemical pulp. The lining is divided into at least one ceramic wear layer (4) having a low porosity, a high density and a high thermal conductivity, which is mounted internally to the reaction chamber, and an outer ceramic backing layer (3) that has a lower density and a lower thermal conductivity. The first and second ceramic layers (4 and 3) have suitable thermal conductivities and thicknesses to ensure that the condensation or solidification point (SP) for the resulting gasification products always lies inside the second layer, irrespective of the effective degree of wear and tear of the first layer. The invention also relates to a process for maintaining the desired temperature profile in the lining.
