REFRACTORY LINING OF COAL GASIFIERS

摘要

Coal gasifiers for the production of reducing gas are protected-at least in parts-by a refractory lining of unburned, carbonaceous magnesia bricks having a carbon content of 5 to 30 percent by weight. The component of these magnesia bricks consisting of sinter and/or fused magnesia suitably has a Fe2O3 content below 6 percent by weight, preferably below 1.5 percent by weight, and a SiO2 content below 3 percent by weight, preferably below 1 percent by weight.
