在火管锅炉管板和平封头的结构设计、强度计算以及受力分析时,常常迂到“呼吸距离”或“呼吸地位”这个词,那么什么叫呼吸距离,它的作用是什么? 以兰开夏锅炉的为例,这种锅炉的长度一般有10米左右,炉排放在炉胆内。炉胆、锅筒壁的上半部、锅简壁的下半部,这三部分的长度是相同?
In the structural design, strength calculation and stress analysis of the head and the head of the fire tube boiler tube plate, it often leads to the word “breathing distance” or “breathing position”. So what is the breathing distance and what is its function? Kaixia boiler, for example, the length of this boiler is generally about 10 meters, furnace discharge in the furnace.
