<p>Disclosed herein is an oil burner system for burning residual type fuel oils in a high temperature combustion zone or chamber, which includes a method and apparatus for operating the system to maintain the fuel oil at a low viscosity while preventing thermal failure by destruction of the burner which protrudes into the combustion zone or chamber. The fuel oil is preheated and introduced into an oil tube extending through a high temperature furnace wall into the combustion zone or chamber, and also a heated fluid is introduced into the oil tube for passage therethrough with the fuel oil, while the outer periphery of the oil tube is cooled where it passes through the furnace wall and into the high temperature combustion zone or chamber, as well as fabricating the oil tube from a material having a low coefficient of thermal conductivity.</p> |
