Waste fuel is transported from a fuel hopper to the combustion chambers by a rotating screw conveyor having the spiraling auger blades. Speed of screw conveyor rotation controls the consumption of waste fuel and, thus, the amount of thermal energy generated in the burner. The burner system includes an intelligent control system for controlling operation of the burner system, so that the burner system performs at optimum efficiency, safely and with minimum operator intervention. | 12-20-2012 |
