High blast torch – ESA Pyronics
High blast torches use a small amount of high-pressure air to pick up incoming gas at the mixer, with 10% of the air passing through a primary venturi that inspirates the gas flow and elevates its pressure. The suction effect allows for low-capacity injectors, as 90% of the air is inspirated from outside. The high-pressure air valve and primary air shutter provide wide adjustment ranges, while the injector-type design of the high-pressure stage prevents air feedback into the gas line.
High Blast Torches: Nozzle, Venturi Mixer, and Pressure Regulation
High blast torches are equipped with a nozzle and venturi mixer design. They use a small amount of high-pressure air to pick up incoming gas at the mixer. 10% of the total air required is passed through a primary modified venturi, which inspirates the gas flow and elevates its pressure.
The suction effect allows for the use of low-capacity injectors because 90% of the air required is inspirated from outside. The high-pressure air valve and primary air shutter provide wide ranges of adjustment. The injector-type design of the high-pressure stage prevents air feedback into the gas line.
This advanced torch technology enables precise control and efficient gas mixing for various industrial and welding applications. The combination of the venturi mixer and pressure regulation features optimizes gas flow and combustion performance.
