Evaluation of refractory liner materials for use in nonslagging high BTU coal-gasifier reactors.
Am Ceram Soc Bull 58(7):705-709, 714
Refractories were evaluated for hot-face liners for nonslagging, high btu coal gasifiers. Tests were conducted at high pressure and temperature conditions in the presence of steam, h2, CO, co2, and a mixture of these gases containing nh3 and h2s. Results indicate that calcium aluminate-bonded refractory concretes made from fire clay calcine aggregate and medium-purity cement and/or refractory brick containing 50 to 90 percent alumina perform better than refractory concrete made from tabular alumina and high-purity cement. Silicon carbide-based refractory linings should not be used. High alumina phosphate-bonded ramming mixes should be adequate as patching materials.
