MULTIFIRE® Industrial Burners incorporate a nozzle-mix refractory block design capable of “on-ratio” firing over a broad range of operating conditions. The dual fuel capability allows MULTIFIRE® Burners to fire on either gas or oil. Maximum application flexibility is provided with five different sizes and “on-ratio” capacities up to 17,500,000 Btu/hr (5120 kW) per burner. In addition, MULTIFIRE® Gas Burners atomize fuel oils with low pressure combustion air eliminating the need for compressed air or steam.
