High Velocity Single Tunnel Dual Fuel Burners
Nozzle-mixing high velocity burner which will burn most gaseous fuels as well as light distillate oils.
The Hot Shot Dual Fuel (HSDF) series is a nozzle-mixing high velocity burner which will burn most gaseous fuels as well as light distillate oils. With either fuel being used the products of combustion are high velocity gases which provide fast penetration and improved temperature uniformity to the work in a furnace. As a result, greater efficiency is obtained and greater fuel savings realized. Being able to switch from one fuel to another without interruption gives the user great versatility in areas where gaseous fuels may be curtailed. The HSDF series will operate on ratio and with excess air or gas for additional versatility.
