LVWO Waste Oil Boiler - Columbia Heating

UNIQUE CHARACTERISTICS OF BURNING USED OIL IN A BOILERA. Accumulation of ash produces numerous adverse affects:1. Reduced heat transfer (U.S. Bureau of Mines) Research by the U.S. Bureau of Mines hasdetermined that 1/32-inch of soot coating causes 9.5% loss of boiler efficiency. Thefollowing table shows how soot thickness effects efficiency1/32-inch of soot1/16-inch of soot1/8-inch of soot3/16-inch of soot9.5% loss of efficiency26% loss of efficiency45% loss of efficiency69% loss of efficiency2. Reduced air flow also causes incomplete combustionFrequently Used Boiler TermsBTU - British Thermal Unit, amount of energy to raise one lb. of water one degree F.1000 BTU = 1 lb. of steam 150 BTU = 1 sq. ft. of hot water34.5 lbs. steam/hr. = 1 boiler horsepower 1 Boiler hp = 140 sq. ft. steam radiation240 BTU = 1 sq. ft. of steam 34,500 BTU = 1 Boiler horsepower1 Gallon of #2 Oil = 140,000 BTU 1 Cu. ft.
