刚性梁上还装有设t锅炉膨胀中心所必需的导向装里.由于刚性梁布里在炉外,结构设计时要充分考虑炉壁热膨胀的影响,连接处允许有一定的相对位移. 刚性梁系统的设计与受它保护的受压部件密切相关,必须以管子的应力分析为基础,使管子和刚性梁本身在炉膛设计压力、风载和地展荷载作用下有足够的强度和刚性。各层刚性梁的间距要满足应力分析的要求并考虑整体布t的合理性;刚性梁的最大挠度也不应超出允许值。对于管子允许变形较小的特殊部位,应严格计茸并采用专门结构。gongxlng}long刚性梁(buckstay)围绕并悬挂在悬吊式炉炉壁外周,对炉壁起保护作用的钢结构系统。它的用是增强炉膛和尾部烟道的刚性,减小炉墙的振动,防止炉墙因变形过大而开裂(如图)。当炉膛内压力剧变化,如燃料爆燃或因熄火等原因造成外爆或内时,可保护管子不受损坏。对于设置了膨胀中心的炉,还可起到固定膨胀中心的作用,并将锅炉受到的载、地震荷载和导向荷载传递到钢结构上。里,七卜J人当肺.盯口月吸固回带 冈JJ性梁 刚性梁按其结构可分为绕带式和栅格式两类。格式刚性梁只用于大容量或双炉膛锅炉,中国制造锅炉多采用绕带式。它的特点是,沿炉膛高度每隔乏4m布置一圈用大型号工字钢组成的水平刚性梁.层之间有时还设有垂直布置的槽钢,用以克服刚性自重引起的外翼缘下沉,保持梁的水平。为保证炉膜焰角、冷灰斗、燃烧器等区域的整体刚性,在这些铆往往要采用比较复杂的平面或空间析架系统。对炉也需采用特殊结构的防护。在沿炉高上、中、下的三脸内多聆斤立页且
