There are only a few types of fuels used for combustion in traditional HVOF (High Velocity Oxy-Fuel) systems, i.e., hydrogen, kerosene, methane (natural gas), propane and propylene. While each fuel has some distinct advantages, hydrogen offers some unique advantages:
- Because of its higher thermal conductivity, hydrogen achieves the best heat transfer from the flame to the powder particles despite having an overall lower flame temperature in comparison with the conventional hydrocarbon fuels.
- The performance of the HVOF process depends on the type of fuel, stoichiometric ratio, and combustion pressure, as well as gun design features. The ability to run rich hydrogen flows creates a reducing atmosphere, which lowers oxide production and further improves the quality of the coating.
- Due to the complete combustion of the stoichiometric reactants of hydrogen and oxygen, there are no unburned residuals deposited on the coating.
- In addition, hydrogen can be delivered at sufficient pressures in tubes and bulk liquid tanks that do not require heating pads during the winter months in order to assure sufficient fuel flow to your HVOF booth.
