<p>In the combustion of waste mineral-bearing liquid streams, an improved type of construction for the combustion chamber, for the combustion of waste mineral-bearing liquid streams which permits continuous removal of solid particulate waste is disclosed. An annular water channel is fitted inside of the outer shell of the combustion chamber at the bottom. The bottom of the chamber is closed off with a funnel-shaped, inverted conical floor, having a drain outlet at its center. An opening is provided in the side of the combustion chamber just above the bottom, for the exit of downflowing products of combustion. Water is supplied to the annular channel and flows through a longitudinal gap in the inner wall, to fall onto the funnel-shaped floor plate, to wash down all of the particulate matter that collects on the bottom plate, into the drain. Thus, the waste is removed as it is formed. The refractory lining of the chamber is shaped with an inwardly-directed flange to permit the flow of molten material down the refractory surface onto the funnel-shaped floor plate and to protect the water channel from direct heating by the flame in the combustion chamber.</p> |
