In the history of boiler development, there has always been accompanied by a catastrophic explosion of boilers. Although it has obviously decreased now, it still happens from time to time. According to records, there were about 10,000 boiler boilers exploding in the United States, Canada and Mexico over the 40 years from 1870 to 1910 ~ ([1]).

Historically there have also been heavy losses of more than 1,000 people on board the ship boiler explosion killed ~ (1). In 1955, a drum in a 2.2M P a, 10t / h steam boiler of a textile factory in China exploded, causing the boiler to rise from the base and fly to another factory beyond 75m. For more than 30 years, our country
