Is a melamine molten salt furnace (30 million kcal/h) a special type of equipment?
Without a polar heat carrier, it can’t even be called a boiler
Melting salts are inorganic heat carriers and do not fall under special equipment.
Melt salt furnaces are not explicitly listed in the 2014 “Catalogue of Special Equipment” announcement. I have been in communication with some manufacturing plants these days: some of them do not consider molten salt furnaces to be special equipment, while others determine whether such furnaces fall under the category of special equipment based on the criteria applied to organic heat carrier boilers. The reason given is that molten salt contains oxidizing components, and leaks at temperatures above 250 degrees can easily lead to explosions.
Firstly, it is clear that it does not belong to special equipment. As for explosions caused by leaks in molten salt furnaces, I have not heard of such cases before; molten salt tends to leak easily, and such leaks can lead to corrosion of the pipe walls. Although our molten salt furnace does not fall under the category of special equipment, its design and manufacturing are carried out in accordance with the standards for boiler-type special equipment. The designs require approval from the special equipment inspection agency, while manufacturing is supervised by the local special equipment inspection agency. But this is actually of a commission nature, not mandatory. Also, the manufacturer you are consulting should have ours. . .
In other words, it is sufficient to design and manufacture it in accordance with the regulations for special boilers; without a special equipment inspection certificate, the user does not need to file a report with the local authorities. Is that how it should be understood?
The hazards of molten salt furnaces are no lower than those of other boilers and heat carrier furnaces. It must be a niche item that got through unnoticed. :lol
We have the certificates, but in principle, there is no need to inform the Special Inspection Institute for the installation.
