ACETYLENE: 7 cylinders X 300 cu ft. = 2100 cu ft. CHEMTANE 2: 100 lbs. X 8.83 cu ft. = 883 cu ft.
2100 cu ft. ACETYLENE = 2.37 times more ACETYLENE to do
883 cu ft. CHEMTANE 2 the same job as CHEMTANE 2
**However, keep in mind this analysis is for consumption only.
ACTUAL CONSUMPTION PER HOUR CUTTING 1" STEEL:
ACETYLENE consumes 14.65 cu ft.
CHEMTANE 2 consumes 6 cu ft.
Divide the ACETYLENE consumption by the CHEMTANE 2 consumption to see that you will use 2.44 times more ACETYLENE per hour than CHEMTANE 2. This is more ACETYLENE consumed than in the illustration above, proving that (7) 300 cu ft. cylinders of ACETYLENE will perform equal to only (1) 100 lb. cylinder of CHEMTANE 2.
7 ACETYLENE cylinders X 300 cu/ft = 2100 cu/ft 2100 cu/ft X 1470 BTUs per cu/ft = 3,087,000 BTUs
100 lbs CHEMTANE 2 X 8.83 cu/ft per lb = 883 cu/ft 883 cu/ft X 2810 BTUs per cu/ft = 2,481,230 BTUs
ACETYLENE FACTS ACCORDING TO ACETYLENE MANUFACTURER:
14% to 16% trapped in cylinder (waste)
Truth Is: 20% trapped in cylinder (MORE waste)
Based on 20% loss the following holds true:
2100 cu/ft. X 80% = 1680 cu/ft of useable gas per (7) cylinders
This is 240 cu/ft per cylinder. (1680 divided by 7 = 240)
240 cu/ft X 1470 BTUs per cu/ft = 352,800 BTUs
COMPARISON:
2,481,230 BTUs = 7.032 cylinders of Acetylene
352,800 BTUs to 1 cylinder of CHEMTANE 2
ACETYLENE (20% Loss // 1" Steel):
1680 cu/ft (divided by) 14.65 cu/ft used per hour = 114.7 hrs. of production
15" per minute X 60 minutes = 900" per hour
900" per hour X 114.7 working hours = 103,230" total production per 7
cylinders of ACETYLENE
CHEMTANE 2 (1" Steel):
100 lbs = 883 cu/ft
883 cu/ft (divided by) 6 cu/ft used per hour = 147.2 hrs. of production
19" per minute X 60 minutes = 1140" per hour
1140" per hour X 147.2 working hours = 167,808" TOTAL PRODUCTION
per 100 lb cylinder of CHEMTANE 2.
USING CHEMTANE 2 THERE WERE 64,578 MORE INCHES CUT THAN WITH ACETYLENE. THIS EQUALS 63% MORE PRODUCTION.
RESULTS IF THERE WAS NO LOSS WITH ACETYLENE:
2100 cu/ft (divided by) 14.65 cu/ft used per hour = 143.3 hrs. of production
15" per minute X 60 minutes = 900" per hour
900" per hr X 143.3 = 128,970" total production per 7 cylinders of ACETYLENE
167,808" Total production with CHEMTANE 2
128,970" Total production with ACETYLENE
167,808 - 128,970 = 38,838 More with CHEMTANE 2
38,838" (divided by) 128,970 = .301 or 30% MORE PRODUCTION WITH CHEMTANE 2 THAN WITH ACETYLENE
