　　What is an inspection-free boiler? How are inspection-free boilers defined?

　　Inspection-free boiler means that after the user purchases the boiler, there is no need to apply for a special equipment license during use, that is to say, both purchase and use. Generally speaking, steam generators, small boilers, and atmospheric boilers are all inspection-free boilers, and it is not possible for any manufacturer to manufacture inspection-free boilers. Manufacturers must hold the "Special Equipment Manufacturing License" issued by the General Administration of Quality Supervision, Inspection and Quarantine. , The products must also comply with relevant national standards such as the Safety Supervision Regulations for Small and Atmospheric Hot Water Boilers.

　　Regarding the definition of inspection-free boilers, we follow Article 99 (1) of the "Special Equipment Safety Supervision Regulations": Boilers refer to the use of various fuels, electricity or other energy sources to heat the liquid contained to certain specifications. For equipment that outputs heat energy externally, its scope is specified as a pressure-bearing steam boiler with a volume greater than or equal to 30L; a pressure-bearing hot water boiler with an outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and a rated power greater than or equal to 0.1MW ; Organic heat carrier boiler.

　　According to the definition of boilers in the "Special Equipment Safety Supervision Regulations", steam boilers with a water capacity of less than 30L, hot water boilers with an outlet pressure of less than 0.1MPa, and atmospheric boilers are all exempt from inspection.
