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. 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 cumbustion chamber.

Combustion chamber for combustion disposal of waste mineral bearing

A method and apparatus of converting hazardous waste fluids into non-hazardous effluent gases within a boiler environment.

Hazardous waste steam generator

Apparatus for burning the gaseous and carbon particulate products from a kiln in which carbon is being calcined, including a pair of vertical cylindrical vessels, to which the effluent products of calcining are carried, by means of an input conduit, which enters the first vessel in a tangential manner near the bottom end, so that the gases will circulate circumferentially in a spinning flow inside of the vessel, as they progress upwardly to a outlet near the top of the first vessel, which leaves tangentially, and passes to the second vessel and enters it tangentially. The gases then circulate around the inner wall of the second vessel spin flowing downwardly, where they leave near the bottom to enter the stack. Means are provided on the entrance conduit for injecting combustion air into the inlet conduit prior to entry of the effluent products into the first vessel. Water may be included with the combustion air, if desired, which is sprayed into the combustion air, and mixes with the effluent products causing immediate combustion of the combustible gases, and of the carbon particles.
