Configuration mode of refractory material of cone bottom of top spraying type coal water slurry gasification furnace
The invention belongs to the technical field of refractory materials, and mainly relates to a configuration mode of a water-coal-slurry gasification furnace lining refractory material. The cone bottom furnace lining of the coal water slurry gasification furnace is composed of a working lining refractory material which is in direct contact with molten slag and a backing refractory material which is not in direct contact with the molten slag, wherein the working lining refractory material is a Cr2O3-free silicon carbide-oxide composite shaped refractory material product; the material of the backing refractory material is an Al2O3-SiC-C composite refractory material amorphous bulk material which does not contain Cr2O3; the thermal-state breaking strength of the silicon carbide-oxide composite refractory material under carbon burying at 1400 DEG C is 25-50 MPa, and water-cooling thermal shock at 1100 DEG C to room temperature is more than or equal to 20 times; and the thickness of the working lining refractory material is 30-50% of the sum of the thicknesses of the working lining refractory material and the backing refractory material. The furnace lining has the remarkable advantages of being environmentally friendly, long in service life, safe and the like, and greenization, long service life and light weight of the furnace lining can be achieved.
本发明属于耐火材料技术领域，主要涉及一种水煤浆气化炉炉衬耐火材料配置方式。水煤浆气化炉锥底炉衬由直接接触熔渣的工作衬耐火材料和不与熔渣直接接触的背衬耐火材料两部分，工作衬耐火材料材质为不含Cr2O3的碳化硅‑氧化物复合定型耐火材料制品；背衬耐火材料材质为不含Cr2O3的Al2O3‑SiC‑C复合耐火材料不定形散状料；碳化硅‑氧化物复合耐火材料1400℃埋炭下热态抗折强度25～50MPa，1100℃～室温水冷热震≥20次；工作衬耐火材料厚度为工作衬耐火材料与背衬耐火材料厚度之和的30%～50%。本发明具有绿色环保、长寿、安全等显著优势，可实现炉衬的绿色化、长寿化和轻量化。
