NOTES:
1. Boiler model suffix “62” indicates 6.15 sq. ft. F.S.H.S. /HP and “50” indicates 5 sq. ft. F.S.H.S./HP
. Firing rate based on:
Natural gas @ 1000 BTU/cu. ft. and 80% heat transfer efficiency
#2 oil @ 138 MBH/gal. and 80% heat transfer efficiency
#6 oil @ 150 MBH/gal. and 80% heat transfer efficiency
* 100% coal input @ 13,000 BTU/pound and 78.5% heat transfer efficiency (6.15 rating)
** Coal input @ 1 ,000 BTU/pound limited to 70% of input in order to develop sq. ft. rating.
. Furnace volume is measured from the bottom of the boiler mud leg (no deduction for bridgewall)
. Approximate dry weight includes H columns and base casing.
