Hydrotorch assembly

Abstract

The present invention is a hydrotorch assembly that is configured to use compressed air for extinguishing flame to prevent the burnback and explosion. The hydrotorch assembly includes a hydrogen source and a hydrogen supply line having a first end connected to and in fluid communication with the hydrogen source. A torch having a first gas conduit is also provided. The first gas conduit includes an inlet connected to a second end of the hydrogen supply line, and an outlet connected to and in fluid communication with a nozzle through which exiting gas is ignited to produce a flame that extends outwardly from the nozzle. A compressed air source, and a compressed air supply line having a first end connected to and in fluid communication with the compressed air source, and a second end connected to the first gas conduit of the torch near the inlet and in fluid communication with the first gas conduit and the hydrogen supply line is also provided. A control valve is disposed in the compressed air supply line for controlling the supply of compressed air to the first gas conduit of the torch.
