ABSTRACT:
Waste gasses generated in the process of manufacturing cores and castings are collected and inventively routed to a heat treating furnace for incineration. Additionally, as a portion of the waste gas is being routed, it is put to use in the reclaiming of uncured scrap materials and the reclaiming of sand within the furnace. Additionally, provisions are made for decreasing the height of the furnace by decreasing the height of hoppers therein and increasing the size of the base of the hoppers to maintain proper flow of reclaimed sand and portions of core materials being reclaimed therein toward the base of the hopper. Multiple fluidizers are employed in the base of the hopper to accommodate for the increased size of the base of the hopper and maintain optimum flow of materials toward the base and optimum fluidization of the materials within the hopper.
