气化炉炉口塞
摘要：
本实用新型气化炉炉口塞主要涉及一种合成氨及甲醇生产过程中的四喷嘴气化炉炉口封堵装置。该气化炉炉口塞由浇注料机械振捣浇注成型，内含耐热钢结构骨架，其特征在于所述钢结构为“丁”字形与“几”字形的焊接，“几”字形钢骨架顶端为圆弧状，钢结构表面涂抹或者缠绕有高温挥发的保护材料，塞体砖表面包覆有耐火纤维毡。本实用新型在保持浇注成型生产方便快捷的同时，克服了其经常出现的拔出失败问题，使炉口塞可以反复使用，能够保证安全生产，并且更换方便、使用寿命长。
摘要（英）：

The utility model relates to a furnace mouth plug of a gasification furnace, in particular to a furnace mouth plugging device of a four-spraying nozzle gasification furnace used during production processes of synthesis ammonia and methyl alcohol. The furnace mouth plug of the gasification furnace is molded by mechanical vibration and casting of a castable material and a heat resistant steel structure frame is arranged in the furnace mouth plug. The furnace mouth plug is characterized in that the steel structure is formed by welding of a t-shaped structure and an n-shaped structure, the top of the n-shaped steel frame is in an arc shape, the surface of the steel structure is coated or wound by a high-temperature volatile protecting material, and refractory fiber felt is wrapped on the plug body brick surface. According to the furnace mouth plug of the gasification furnace, the casting molding production is convenient and rapid, the problem of frequent extraction failure is solved, the furnace mouth plug can be used repeatedly, the safety production can be guaranteed, and the furnace mouth plug is convenient to replace and is long in service life.
