具体实施方式
图1为现有垃圾焚烧炉边墙炉排片的结构示意图。图中显示，现有技术中，垃圾焚烧炉边墙炉排片为分体式插接组合结构。边墙炉排片由安装组件4、固定座2及盖板1组成，其中，在固定座2设置有滑槽2.1a、2.1B，在盖板1上相应设置有滑柱1.1a、1.1b，通过滑槽与滑柱之间的插合使固定座2与盖板1插接固定。安装时，先将炉排固定座2通过安装组件4安装固定在炉体左右两侧的侧墙上，然后再将盖板1插合固定在固定座2上。
图1中显示，现有技术中，边墙炉排片安装固定在炉体左右两侧的侧墙上，其盖板外侧面1.2b与炉膛内部炉排保留一定的边墙间隙3并且此间隙不可调整。由于边墙间隙3与炉底相通，一次风从炉底通过边墙间隙3进入炉膛，一次风的多少与垃圾的燃烧率成正相关，边墙间隙的大小与一次风进入的多少也成正相关。因此，由于现有垃圾焚烧炉的边墙炉排片安装时存在边墙间隙，这个间隙使一次风由炉膛底部从侧面进入炉膛上面，导致炉膛内部出现两边垃圾燃烧快而中间垃圾燃烧慢的问题，严重影响垃圾焚烧炉的 正常运行。
图2-图5为本发明一个实施的结构示意图，其中，图2、图3为零件结构示意图，图4、图5为使用状态结构示意图。
图中显示，本例中，垃圾焚烧炉边墙炉排片为分体式插接组合结构。边墙炉排片由安装组件4、固定座2及盖板1组成，其中，固定座2具有滑槽2.1a、2.1B，盖板1上相应设置有滑柱1.1a、1.1b，通过滑槽与滑柱的插合使固定座2与盖板1插接固定。安装时，先将炉排固定座2通过安装组件4安装固定在炉体左右两侧的侧墙上，然后再将盖板1插合固定在固定座2上。与现有技术不同的是，本例中，固定座2上的滑槽与盖板1上对应的滑柱在插合时两者之间具有补偿间隙，补偿间隙可以使盖板1发生平移。在盖板1与固定座2的贴合面之间还设置有耐高温弹簧6。一次风作用在盖板1外侧面1.2b上，耐高温弹簧6的压力作用在盖板的内侧面1.2a上。由于此两个力的方向相反，在焚烧炉运行过程中，由于耐高温弹簧6的弹性系数不变，但一次风的压力可以调整。因此，在盖板1外侧面1.2b与炉膛内部炉排之间的边墙间隙3随着一次风压力的变化而变化。
图4、图5显示，在垃圾焚烧炉的运行过程中，耐高温弹簧6的弹性系数通过设计确定。当一次风作用在盖板1外侧面1.2b上的压力小于耐高温弹簧6对盖板1内侧面1.2a产生的压力时，盖板1的外侧面1.2b与炉膛内部炉排之间互相贴合，此时一次风从炉排中间进入炉膛。当一次风的压力增加时，作用在盖板1外侧面的一次风压力超过耐高温弹簧6对盖板1内侧面1.2a产生的压力，耐高温弹簧6收缩，盖板1发生平移，盖板1的外侧面1.2b与炉膛内部炉排之间出现间隙(即边墙间隙3)，此时，此时一次风从炉排中间及两侧进入炉膛。
图4及图5显示，本例中，可以通过调整一次风的压力来改变一次风在炉膛中的流动分布，提高垃圾焚烧效果。
