我厂SHL－10－13链条锅炉是1983年投入运行的，1986年5月发生左右防焦箱鼓泡，最大为150×20×8毫米（长×高×宽鼓泡示于图1），当时为应急生产、采用挖补办法修复。1988年8月在挖补处又发生鼓泡，更换新的防焦箱后，使用不足二年也鼓泡。为此我们走访了同行厂，存在同样问题。对此，我们分析了鼓泡的原因，采取增加上升壁管与引下降管进防焦箱的办法给予改造，经几年运行证明改造是成功的。 Our factory SHL-10-13 chain boiler put into operation in 1983, in 1986 May around the anti-coke bubbling, the largest 150 × 20 × 8 mm (L × H × width bubble shown in Figure 1), At that time, emergency production, using digging repair methods. In August 1988, there was another bubbling at the excavation site. After replacing the new anti-coke box, it used bubbling for less than two years. For this reason we visited the same factory, there is the same problem. In this regard, we analyzed the reasons for bubbling, to increase the wall tube and the introduction of drop tube into the anti-coke box to give transformation, after several years of operation proved successful transformation.
