Requirements for fired boilers of various sizes and uses are referenced in table 1 to § 54.01-5 of this subchapter.
§ 52.25-3 - Feedwater heaters (modifies PFH-1).
Feedwater heaters must meet the requirements in PFH-1 of Section I of the ASME BPVC (incorporated by reference; see § 52.01-1).
§ 52.25-5 - Miniature boilers (modifies PMB-1 through PMB-21).
Miniature boilers must meet the requirements in PMB-1 through PMB-21 of Section I of the ASME BPVC (incorporated by reference; see § 52.01-1).
§ 52.25-7 - Electric boilers (modifies PEB-1 through PEB-19).
Electric boilers required to comply with this part must meet the requirements in PEB-1 through PEB-19 except PEB-3 of Section I of the ASME BPVC (incorporated by reference; see § 52.01-1).
§ 52.25-10 - Organic fluid vaporizer generators (modifies PVG-1 through PVG-12).
(a) Organic fluid vaporizers must meet the requirements of PVG-1 through PVG-12 of Section I of the ASME BPVC (incorporated by reference; see § 52.01-1).
(b) The Commandant must approve the application and end use of organic fluid vaporizer generators.
§ 52.25-15 - Fired thermal fluid heaters.
(a) Fired thermal fluid heaters must be designed, constructed, inspected, tested, and stamped in accordance with the applicable provisions in this part.
(b) Each fired thermal fluid heater must be fitted with a control which prevents the heat transfer fluid from being heated above its flash point.
(c) The heat transfer fluid must be chemically compatible with any cargo carried in the cargo tanks serviced by the heat transfer system.
(d) Each fired thermal fluid heater must be tested and inspected in accordance with the requirements of subpart 61.30 of this subchapter.
§ 52.25-20 - Exhaust gas boilers.
Exhaust gas boilers with a maximum allowable working pressure greater than 103 kPa gage (15 psig) or an operating temperature greater than 454 °C (850 °F) must be designed, constructed, inspected, tested, and stamped in accordance with the applicable provisions in this part. The design temperature of parts exposed to the exhaust gas must be the maximum temperature that could normally be produced by the source of the exhaust gas. This temperature must be verified by testing or by the manufacturer of the engine or other equipment producing the exhaust. Automatic exhaust gas boiler control systems must be designed, constructed, tested, and inspected in accordance with § 63.25-7 of this subchapter.
