普通硅酸铝耐火纤维毡,是一种耐火性能良好的纤维质耐火材料。有耐高温、施工快、检修方便等特点。近年来在石油工业和石油化学工业的燃烧炉和管式加热炉上应用较广,更由于使用这种炉衬代替耐火粘土砖炉衬或耐火混凝土炉衬,能大大地减轻炉体重量,简化炉体钢结构布置,有提高炉体的延性和炉体抗震性能等优点,目前在加热炉的抗震设计中亦有所应用。通过实例说明耐火纤维毡管板代替立管式加热炉辐射炉管顶部管板的施工方法和使用效果。一、立管式辐射炉管顶部管板的选材这种炉管的顶部管板选材,应能承受高温热烟气的冲刷(600℃左右),所以选用粘土
Ordinary aluminum silicate refractory fiber mat, is a good fire-resistant fiber refractory material. A high temperature, construction fast, easy maintenance and so on. In recent years, it has been widely used in furnaces and tube furnaces in the petroleum industry and petrochemical industry. The use of such furnace lining instead of refractory clay brick linings or refractory concrete linings can greatly reduce the weight of the furnace body and simplify the furnace steel The structural arrangement has the advantages of improving the ductility of the furnace body and the seismic performance of the furnace body, and is also applied in the seismic design of the heating furnace at present. An example is given to illustrate the construction method and the use effect of the refractory fiber felt board instead of the vertical tube plate on the top of the furnace tube. First, the vertical tube radiant tube material selection at the top of the tube This tube top plate selection, should be able to withstand high temperature hot flue gas erosion (about 600 ℃), so the choice of clay
