  • Patent number: 12071723
    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.

  • Patent number: 11592175
    Abstract: An assembly for cleaning a smelt spout includes a cleaning head, a drive rod connected with the cleaning head, and a pneumatic or other drive connected to selectively extend or retract the drive rod. The drive rod may be connected with the cleaning head by a pivotal connection. The cleaning head may be bifurcated. The cleaning head may include a leading edge configured to engage and clean a spout opening from which smelt from a chemical reduction furnace flows to the spout. The assembly may further include a pivot point and, as the drive selectively extends the drive rod, torque about the pivot point produced by the cleaning head and an extending portion of the drive rod rotates the cleaning head downward to engage a smelt spout.

  • Patent number: 6909495
    Abstract: An emissivity probe for measuring reflected energy from interior wall surfaces of large scale boilers. The emissivity probe uses a pair of light guides which respectively receive light energy from the interior of the boiler and that reflected off a wall surface. Using appropriate photo detectors sensitive to a desired light wavelength range, a ratio of the reflected and incident radiation is provided. This provides a measure of the reflectivity of the wall surface. The reflectivity values are used to control boiler cleaning systems.
