What is a boiler?
Alberta Regulation 49/2006 defines it as “a vessel in which steam or other vapour may be generated under pressure or in which a liquid may be put under pressure by the direct application of a heat source.” Other legislation and code define it in similar ways. CSA B51 Boiler, Pressure Vessel and Pressure Piping Code, defines it as “as a vessel under the Act”. By ‘Act’, CSA B51 refers to the governing statute in each provincial or territorial jurisdiction. For all boilers registered with a CRN in Canada, in the absence of a Variance issued by the jurisdictional regulatory authority, the requirements of ASME Section I must be met in its entirety.
