从本世纪初开始,煤的完全气化技术有很大发展,出现了许多气化方法和炉型,因而也产生了好几种分类方法。从炉子机械化程度分,有人工的、半机械化的和机械化的炉子。从气化剂性质分,有空气、水蒸气、空气和水蒸气、氧气和水蒸气以及氢气等作为气化剂。从炉内压力分,有常压和加压的炉子。从灰渣排除形式讲,有干灰、团渣和溶渣法之分。从炉内气、固相物料相对运动方向来说,有顺流、逆流和错流之分。对于
Since the beginning of this century, there has been a great development in the technology of complete gasification of coal, and many gasification methods and furnaces have appeared. Therefore, several classification methods have also emerged. From the furnace degree of mechanization points, there are artificial, semi-mechanized and mechanized stove. From the nature of gasification agent, there are air, water vapor, air and water vapor, oxygen and water vapor and hydrogen gas as a gasification agent. From the furnace pressure points, there are atmospheric pressure and pressure of the stove. From the exclusion of forms of ash, there are dry ash, slag and slag law of the points. From the furnace gas, solid phase material relative to the direction of movement, there is co-current, counter-current and cross-flow points. for
