在新建的中洛管线上采用了一种工厂预制、现场组装的新型快装高效加热炉,其最大热负荷为8 400MJ/h。整个炉子分以下部分:辐射段、对流段、空气预热器(包括供风系统)、烟囱、吹灰器等。其中辐射段为卧式圆筒形,辐射管为φ127×6钢管,两管程排列,加热面积 69m~2;对流段为立式方形,对流管为φ102×8钉头管,四管程排列,加热面积31m~2;空气预热器位于对流段上部,由501根φ45×1.5的钢管组成,预热面积123m~2;为了防止对流炉管的钉头和空气预热管挂灰,影响烟囱抽力,降低传热效
In the new Zhongluo pipeline using a factory prefabricated, the site assembled a new type of fast and efficient furnace, the maximum heat load of 8 400MJ / h. The whole furnace is divided into the following parts: radiation section, convection section, air preheater (including air supply system), chimney, soot blower and the like. The radiating section is horizontal cylindrical, the radiating tube is φ127 × 6 steel tube, the two tubes are arranged with heating area of 69m ~ 2; the convection section is vertical square, the convection tube is φ102 × 8 nail tube, , The heating area of 31m ~ 2; air preheater is located in the upper convection section, composed of 501 φ45 × 1.5 steel pipe, preheating area of 123m ~ 2; In order to prevent convection tube nail head and air preheating pipe hanging ash, the impact Chimney pumping force to reduce heat transfer
