Riello Burner: a sharp clean light off with close to zero smoke.

Have you ever wondered why a Riello Burner seems to operate so much cleaner than either a Beckett or a Carlin? It can't be burning any cleaner; zero smoke is zero smoke. The big difference is Riello's insistence on pre-purge.

During start-up of a burner without pre-purge the oil valve in the pump opens at about 2400 RPM. At this point of start-up you only have 80% of the required air available and the end result is smoke until everything gets ironed out. You might think it's only a few seconds and won't make any difference, but let me remind you that the average oil burner starts thousands of times a year and soot is accumulative.

Now if you use pre-purge the burner has time to come up to speed and some draft will be established. The end result is a clean sharp light off with close to zero smoke.
