A thermal spray apparatus is provided for thermal spraying a coating onto a substrate. The apparatus include a heating module for providing a stream of heated gas. The heating module is coupled to a forming module for controlling pressure and velocity characteristics of the stream of heated gas generated by the heating module. The thermal spray apparatus further includes a barrel capable of directing the stream of heated gas from the forming module. A powder injection module may be provided for introducing powder material into the stream of heated gas.

High velocity thermal spray apparatus

A combustion apparatus is provided having a pre-combustion chamber and a combustion chamber. The pre-combustion chamber houses a preheating combustion for preheating and at least partially vaporizing fuel supplied to the pre-combustion chamber. The preheating combustion is controlled so that only a portion of the fuel supplied to the pre-combustion chamber is burned. The combustion apparatus further include a primary combustion oxidizer supply located downstream of said preheating combustion. The primary combustion oxidizer supply supplies an amount of oxidizer to allow the fuel not burned by the preheating combustion to burn.
