Dual Fuel Burner - 3562

Burner Operation

Oil with a viscosity of 70 to 90 seconds Redwood I and a pressure between 25 and 30 psi, should be supplied to an Air/Oil ratio controller which will deliver oil to the burner at a pressure proportional to the main air pressure, thus maintaining the correct air/oil ratio at all firing rates. The atomizing air pressure at the burner may be as low as 28”wg when using distillate oil, 38”wg when using heavy oil. The 3562 burners can operate on any gas of 2000 to 12800 kcal per cubic feet heating value. Switching from gas to oil operation or oil to gas may be done quickly without furnace shutdown, simply by turning off one fuel valve and opening the other.

Burner Construction

The heavy cast iron body can stand much abuse. All internal parts of the 3562 burner are machined. The smooth surfaces stay free of oil deposits and dirt, thus greatly minimizing the need for cleaning. Oil is put through the burner in a straight passage having a large cross-sectional area permitting visual inspection for clogging and easy clean out if necessary. The burner oil valve is a non-plugging V-port oil valve which produces small and uniform flow rate changes throughout the 180°C sweep of the control handle.
