SULFUR IN FUEL

- for the purpose of 310 CMR 7.05, sulfur in fuel is as follows: (a) Oil 2.2% sulfur content = 1.21 pounds of sulfur per million Btu heat release potential 1% sulfur content = 0.55 pounds of sul fur per million Btu heat release potential 0.5% sulfur content = 0.28 pounds of sulfur per million Btu heat release potential
(b) Coal 1. 57 % sulfur content = 1. 2 1 pounds of sulfur per million Btu heat release potential (assuming 13,000 Btu per pound) 0.72% sulfur content = 0.55 pounds of sulfur per million Btu heat release potential (assuming 13,000 Btu per pound) 0.36% sulfur content = 0.28 pounds of sulfur per million Btu heat release potential (assuming 13,000 Btu per pound)
