Gas orifice is an essential part for gas appliance. Its main function is adjusting the gas flowrate, which directly effect the working condition of burning.
Gas orifice are of two types: convergent and divergent.
The convergent-divergent gas orifices are therefore used to accelerate the fluid which is choked to supersonic speeds in the convergent sections. This process is considered to be more efficient than making the convergent gas orifice to expand externally. The gas orifice are of different types and are commonly round tubes used to perform different functions.
The material is copper, brass, stainless and aluminized steel. Covered area and spraying effect can be adjusted, it can be adjusted to the artificial fog, flat fog effect, simple atomizing effect, which require a low water pressure with far range.
