Is a steam trap survey necessary?<\/strong><\/p>\n1. It takes approximately one lb of steam to generate 1,000 BTU\u2019s.<\/p>\n
2. The energy content of one gallon of #6 fuel oil = 149,700 BTU\u2019s with a combustion efficiency of 86.1%
\n(U.S. Dept. of Energy, Office of Industrial Technologies).<\/p>\n
3. With #6 oil at $1.30\/gallon then:
\n1.30 ($\/gallon) \/ 149,700 (BTU\/gallon) \u00a0 X \u00a0 \u00a0 1000 (BTU\/lb) \u00a0 \u00a0 X \u00a0 \u00a0 .861 (efficiency) \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0=\u00a0$.0075 per lb<\/strong>
\nTherefore the cost of steam is $0.0075\/lb or $7.50\/1000 lbs<\/strong><\/p>\n4. Steam trap hours of use per year:
\nheat season (120 days) \u00a0\u00a0\u00a0 X \u00a0\u00a0\u00a0 12 hours per day = 1440 Hours<\/p>\n
5. Steam loss thru a typical thermostatic trap with a 0.312\u201d (5\/16\u201d) orifice at 5 psi (+ 14.7 psi atmospheric pressure) and 50% blocked (based on a variant of the Napier formula, as follows) = 23.3 lbs\/hr<\/p>\n
Steam flow (to atmosphere) in lbs\/hr:<\/strong>
\n24.24\u00a0\u00a0\u00a0\u00a0 X \u00a0\u00a0\u00a0\u00a0 pressure psi absolute \u00a0\u00a0X\u00a0\u00a0\u00a0\u00a0 diameter of orifice squared\u00a0 \u00a0X \u00a0\u00a0 50% Blockage
\n24.24 \u00a0\u00a0\u00a0\u00a0X\u00a0\u00a0\u00a0\u00a0 (5 psi + 14.7 psi) \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 X \u00a0\u00a0\u00a0\u00a0(.312)(.312) \u00a0 X \u00a0\u00a0\u00a0 .50 \u00a0 \u00a0 \u00a0 = 23.3 lbs\/hr<\/p>\n<\/p>\n
6. Therefore, in one heating season, one trap 50% blocked translates into an effective steam loss cost of approximately $250.00 per trap.
\nsteam loss\/hr \u00a0\u00a0 X \u00a0\u00a0 heating season \u00a0\u00a0 X \u00a0\u00a0 cost of steam per lb = cost per season per trap
\n23.3 lbs\/hr \u00a0\u00a0 X \u00a0\u00a0 1440 hrs \u00a0\u00a0 X \u00a0\u00a0 $0.0075 per lb = $250 per season per trap<\/p>\n
Yes, a Steam Trap survey is necessary! It does pay to inspect, repair, or replace your steam traps!<\/strong><\/p>\n
