NOZZLE THROAT FOR THERMAL PROCESSING AND TORCH EQUIPMENT

摘要

A nozzle assembly includes an upper portion defining an opening for receiving a gas and a longitudinally extending cylindrical body portion adjacent to the upper portion and defining a passageway for the gas. The nozzle assembly also includes a tip portion adjacent to the body portion, with the tip portion defining a throat channel. The throat channel includes a throat inlet region that focuses a flow of the gas. The throat inlet region is fluidly connected to the passageway via a throat inlet opening. The throat channel also includes an acceleration region that is disposed downstream of the throat inlet region and fluidly connected to the throat inlet region to compress the gas and accelerate the flow of the gas. The throat channel further includes an expansion region disposed downstream of the acceleration region and fluidly connected to the acceleration region to allow the gas to expand.

1. A nozzle assembly for a torch, the assembly comprising:
an upper portion defining an opening for receiving a gas; a longitudinally extending cylindrical body portion adjacent to the upper portion and defining a passageway for the gas; and a tip portion adjacent to the body portion, the tip portion defining a throat channel, the throat channel including,
a throat inlet region to focus a flow of the gas, the throat inlet region being fluidly connected to the passageway via a throat inlet opening,an acceleration region disposed downstream of the throat inlet region and fluidly connected to the throat inlet region to compress the gas and accelerate the flow of the gas, andan expansion region disposed downstream of the acceleration region and fluidly connected to the acceleration region to allow the gas to expand, the expansion region including a throat outlet opening through which the gas exits the nozzle assembly.
