The boiler in question originally used producer gas and blast furnace gas; blast furnace gas was used primarily as the fuel, while producer gas was used when the blast furnace was under maintenance or when the pressure of blast furnace gas was insufficient. Producer gas was mainly employed to ensure that the fire did not go out. I now want to switch from producer gas to natural gas + blast furnace gas; after consulting relevant manufacturers, it is only necessary to replace the burners. Before starting this construction, is it necessary to go to the Quality Supervision Bureau to submit a start-up notification, and are supervision inspections required? (Where can this be found in relevant laws and regulations?) Is it considered a modification, a major repair, or a routine repair? If notification is required, the submitted design plans and drawings must bear the seal indicating qualification for boiler design; does the construction unit need to have qualifications for boiler modification and repair?
According to the Boiler Safety Inspection Regulations, it is not necessary to do so; however, point 5 of the “Notice from the General Office of the Quality Inspection Administration on Risk Warnings Regarding Gas Boilers, 2017” at http://bbs.hcbbs.com/thread-1668793-1-1.htm states that: “The modification or replacement of boiler burners must follow the relevant procedures for notifying authorities when carrying out such repairs.” I think the regulations regarding boiler management are too complicated; they’re not explained clearly, which makes it a bit hard to understand.
It’s best to consult the boiler inspection agency!
No need! If no one has been found to do this, I’ll do it for you, and I can also supply LNG at a low price on a long-term basis.
It’s better not to make any changes; the results won’t be good. Currently, **there are increasing demands for environmental protection and energy conservation**
Inspection isn’t required, but the boiler supervision department of the quality supervision bureau says it is. It is estimated that this requirement was put in place after the General Office of the Quality Inspection Administration issued the \"Notice on Risk Warnings Regarding Gas Boilers\" on January 24 of this year. This task, which costs just a few bucks, doesn’t require your help – it’s already been done.
Just switch to a low-nitrogen burner; otherwise, it will need to be changed again later
