METHOD OF PROTECTING A COAL GASIFIER PART FROM ATTACK BY LIQUID SLAGS

摘要

Coal gasifiers for the production of reducing gas are protected - at least in part - 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 Fe203 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.
