Dale and Pete. When we installed the new boilers in the Belle of Louisville the National Burner Co. made the firing nozzles, etc. We had no problem with smoke - we just couldn't get enough heat to sustain the steam pressure and volume needed. There was a small brass disc in the burner with five holes in it. As I remember it, the center hole was for steam to atomize the oil. The four periferal (ain't that a elegant word?) holes supplied the oil. They were drilled no. 66 at the factory. Their engineer told me to take that disc to a machine shop and have them drilled out to no. 65. That increased the diameter from 0.0330" to 0.0350", or two thousandths of an inch. We did as suggested and those burners took off like a volcano.
