Steam Loss Calculator

Using Napier’s formula we can approximate the amount of steam leaking through a failed trap. The cost of steam includes the cost of the fuel as well as the cost of make-up water, chemicals, boiler operation and maintenance expenses.

*  NOTE: estimates of total number of traps leaking in a system are as follows:

  • 50% leak if no trap survey and maintenance performed
  • 25% leak if trap survey and maintenance performed annually
  • 9-12% leak if trap survey and maintenance performed quarterly
  • 3% leak if trap survey & maintenance performed monthly
Amount Lost:  lbs/hr X  hrs/day =   lbs/day
Daily Cost:  lbs/day X  steam cost =   cost/day
Total est. Loss per Year:  cost/day X  days/year =   loss/year
Annual Loss:  # traps X  loss/year =   annual loss
