Abstract
A smelt shattering apparatus includes an inlet orifice, an outlet orifice, and a fluidic pathway between the inlet orifice and the outlet orifice. A convergence divergence zone is located between the inlet orifice and the outlet orifice. In one illustrative construction, a first separable section includes the inlet orifice, and a second separable section includes the outlet orifice and a divergence zone of the convergence divergence zone. In some constructions, there may be a second outlet orifice in fluidic communication with the inlet orifice. To provide uniformity over the multiple shatter jets, the first outlet orifice may have a cross-sectional dimension and the second outlet orifice is located a distance of between about 4 and about 10 times of the cross-sectional dimension from the first outlet orifice.
