Installation of matched boilerburner or furnaceburner systems. Three elements must exist together in order for combustion to take place.

The key to efficient furnace operation lies in complete combustion of fuel with minimum excess air. This can be as simple as adjusting an air shutter, changing gas pressure or as involved as changing an oil nozzle. The normal sulfur content for the residual fuel oil furnace oil is in the order of 24 %. O 10,700 furnace oil 10,500 lshs 10,600 sulphur the amount of sulphur in the fuel oil depends mainly on the source of the crude oil and to a lesser extent on the refining process.

However, pm emissions from residual oil burning are related to the oil sulfur content. Microscopic examination of the col lected particles ruled out coalburning installations, sootblowing operations, or boilercleaning practices as the major source. This can be as simple as adjusting an air shutter, changing gas. Whether working on gas, oil, coal, or wood fired appliances it is imperative to perform a combustion analysis during routine service, or any time changes are made that will affect the combustion process.
