在很多链条炉排的锅炉中,防焦箱是按一般方式(图1,a)和循环系统接通的。这些防焦箱往往发生弯曲;防焦箱愈长,弯曲得愈厉害。图1 防焦箱与循环系统的连接方式α—一般方式;σ—非一般方式;1—不受热的下降水管;2—受热的管子;3—不受热的下降水管。弯曲的拱度随着投入运行的次数而增加;尽管有保持其伸直的加固装置,在个别的情况下,弯曲拱度还要达到50公厘。在目前情况 In many chain grate boilers, the pyrophosphate boxes are normally connected (Figure 1, a) to the recycle system. These anti-coke tend to bend; longer anti-coke box, bending more powerful. Figure 1 Coke box and the connection of the circulatory system α - the general approach; σ - the non-general way; 1- does not heat down the water pipe; 2-heated pipe; Bending camber increases with the number of operations; in spite of the stiffening devices which maintain their straightness, in individual cases the camber reaches 50 mm. In the current situation
