  • Patent number: 12260645
    Abstract: Systems, methods, and computer program products of intelligent image analysis using object detection models to identify objects and locate and detect features in an image are disclosed. The systems, methods, and computer program products include automated learning to identify the location of an object to enable continuous identification and location of an object in an image during periods when the object may be difficult to recognize or during low visibility conditions.

  • Patent number: 11852338
    Abstract: An array of tile assemblies is fixedly connected to a common waterwall panel to form a refractory liner for an incinerator. Each tile assembly includes a unitary, clip-type, metallic anchor, which is directly welded to the waterwall panel, and a solid refractory tile slidably connected to the anchor through a dovetail locking mechanism. The rear surface of the refractory tile includes a longitudinal rib from which projects a dovetail pin configured to receive the anchor. The longitudinal rib increases the overall thickness of the refractory tile through the region of interconnection with the anchor. In this manner, the anchor is suitably protected by the refractory tile from intense heat which may otherwise cause mechanical failure in the locking mechanism. Additionally, the solid construction of refractory tile both limits the presence of air gaps within the tile assembly and reduces the likelihood of tile fragmentation or cracking.

  • Publication number: 20210199286
    Abstract: A combustion chamber for use in the incineration of waste products includes an inner refractory wall which extends vertically within an outer protective wall in a spaced relationship so as to define a plenum therebetween. The inner refractory wall is constructed using a plurality of precast, refractory blocks which are stacked and arranged to define a cylindrical interior cavity. The refractory blocks include mating features on adjacent surfaces to facilitate assembly and provide structural support. For additional support, selected blocks are fixedly connected to vertical support tubes by metal tie-back anchors. To facilitate combustion, a selection of the blocks is precast with a tuyere hole in order to deliver a uniform and balanced supply of air from the plenum into the interior cavity. The precast nature of the refractory blocks enables the inner refractory wall to be constructed with great precision, thereby optimizing incineration and minimizing material degradation.
