Heat and Power Equivalency Table

  Condensing Rate (GPM) BTUs/hour #1 Lbs/hour #2 Sq. Ft. EDR
1 Boiler HP (BHP) .069 33,475 34.5 139.4
1,000 Sq. Ft. EDR .50 240,000 247.3 1,000

Examples:

  1. A 500 HP boiler requires what size receiver for 10 minutes storage?
  • Answer: 500 BHP × .069 (gallons per minute) × 10 minutes = 345 gallon receiver
  1. A steam load of 6,695,000 BTUs/hour requires what size receiver for 15 minutes of storage?
  • Answer:
    • Step 1— 6,695,000 BTUs/hour ÷ 33,475 BTUs/hour = 200 BHP
    • Step 2— 200 BHP × .069 (gallons per minute) = 13.8 condensing rate (GPM)
    • Step 3— 13.8 (gallons per minute) × 15 minutes = 207 gallon receiver

Notes

  1. BTUs sometimes expressed as MBH (1,000 BTUs/hour). Convert MBH to BTUs by multiplying the value of MBH by 1,000.
  2. Lbs/hour sometimes expressed as PPH.
