Universal Citation: MN Rules 5225.1000
Current through Register Vol. 49, No. 13, September 23, 2024

In rating the horsepower of a boiler plant, inspectors shall use the horsepower of each boiler and compute the total horsepower of all boilers connected to the header, whether all the boilers are in use or not.

Where the heating surface cannot be discerned, the boiler horsepower shall be determined by calculating Btu boiler-rated input divided by 67,000.

For purposes of operating engineer license requirements, boiler horsepower for conventional boilers and steam coil type generators is determined as provided in Minnesota Statutes, section 326B.978, subdivision 17. For electrically operated boilers for this purpose, ten kilowatts equal one boiler horsepower.
