在我国改革开放初期,引进的燃油蒸汽锅炉外表包装靓丽,燃烧设备比较先进,自动控制程度较高,安全附件灵敏可靠,电动给水水泵密封性能良好。然而,锅炉本体设计结构和制造上有一些缺陷,笔者对当时从美国、英国和德国进口的7台燃油锅炉的检验案例和检验过程的回眸,并对其产生裂纹缺陷的原因进行了点评,其目的是提醒国人不要盲目从国外进口锅炉。1美国CB炉检验案例1.1案例11)锅炉概况:广州市B五星级宾馆1980年从美国购买了3台锅炉型号为CB500-150四回程燃油蒸汽锅炉,其额定压力:1.03MPa;额定出力:7.8t/h;制
In the early stage of China’s reform and opening up, the introduction of fuel steam boiler looks beautiful packaging, combustion equipment is more advanced, a high degree of automatic control, safety accessories sensitive and reliable, electric water pump sealing performance is good. However, the design and construction of the boiler body have some shortcomings. The author reviews the inspection cases and inspection processes of the seven oil-fired boilers imported from the United States, the United Kingdom and Germany at the time, and comments on the causes of crack defects. The purpose is to remind people not to blindly import the boiler from abroad. 1 US CB furnace test case 1.1 Case 11) Boiler Overview: Guangzhou B five-star hotel in 1980 purchased from the United States three boiler model CB500-150 four return fuel steam boiler, the rated pressure: 1.03MPa; rated output: 7.8t / h; system
