Calculators
Free engineering tools.
Boiler Sizing Calculator
Size a steam or hot water boiler from a process load, an equipment list, or a batch heating job. Recommends one boiler, two, or N+1, with fuel cost and the South Coast AQMD rule.
Open the calculator →CalculatorFeedwater Tank and Pump Sizing
Tank gallons, feed pump gpm and discharge pressure per ASME Section I PG-61, an NPSH check for hot water, and preheat steam.
Open the calculator →CalculatorBurner Upgrade Savings
Gas, dollars, and CO2 a new burner saves from your O2, stack temperature, turndown, and how the boiler runs through the year.
Open the calculator →CalculatorLinkage to Linkageless Controls
What parallel positioning, oxygen trim, and a variable speed fan save over a jackshaft linkage, in gas and electricity.

Codes and rules change. The jurisdiction and the boiler’s code of construction govern each job.
Yes. McKenna Boiler Works, Inc.’s calculators are free to use, run in any browser, and don’t ask for an email. Each one shows its math and its sources, and you can copy the results or a share link to send to McKenna.
Published engineering sources: the boiler horsepower definition, standard steam tables, the U.S. Department of Energy’s combustion efficiency table and steam tip sheets, ASME Section I PG-61 for feed pressure, and South Coast AQMD rules for NOx limits. Each calculator page lists its sources.
No. The calculators are for planning and budgeting. McKenna Boiler Works, Inc. engineers confirm the load, pressure, feedwater, burner, and room before quoting, and the jurisdiction and the boiler’s code of construction have the final say.
