Eclipse has added two higher capacity sizes to its popular ThermJet line of furnace burners. The addition of 7.5 MM Btu/hr and 10 MM Btu/hr models brings the complete line to 12 burner sizes. ThermJet burners produce an intense stream of hot gases to thoroughly penetrate the load and deliver precise temperature uniformity for consistent product quality and system efficiency. The new ThermJet burners are available for medium- or high-velocity operation with gas velocities of 250 ft/s and 500 ft/s, respectively. Users can specify their choice of capacity, velocity, combustor type (SS tube, SiC tube, or block and holder), fuel type, thread type and flame sensing components.
