笔者从事多年的大型电站的定期检验和安装过程的监督检验工作,就其中一些不同厂家设计的结构进行比较其优缺点,对一些结构设计提出自己的优化方案,以供行业内交流及设计单位参考。1刚性梁部分1.1水冷壁水平刚性梁结构形式锅炉水冷壁与包墙四侧为增加炉膛强度,需要加设刚性梁,有的厂家刚性梁腹板部分设计为实心整体式,但有的厂家腹板已改为空心结构式,如图1所示。实心式的腹板,改成圆孔形的轻结构型刚性梁,钢材及本身重量减少约1/5,但整体结构的强度基本不受影
The author engaged in many years of large-scale power station inspection and installation of regular inspection and supervision of the work on some of the structures designed by different manufacturers to compare their advantages and disadvantages of some of the structural design put forward their own optimization program for the exchange and design industry reference . 1 rigid beam part 1.1 horizontal wall structure of the water wall structure of the boiler water wall and the wall to increase the four sides of the furnace to increase the strength of the furnace, the need to add rigid beams, and some manufacturers of rigid beam web part of the design for the solid one, but some manufacturers abdomen The board has been changed to a hollow structure, as shown in Figure 1. Solid-type web, into a round hole-shaped light-structure rigid beams, steel and reduce their own weight about 1/5, but the overall structure of the basic intensity of the shadow
