Abstract

1440298 Burning liquid waste COMBUSTION UNLIMITED Inc 24 Oct 1974 [14 Jan 1974] 46103/74 Heading F4T Apparatus for burning flammable liquid waste, comprises a support 10, Figs. 2, 5, including a pivotally-mounted frame 13, a housing 25 having means 27, 28, for controlling the delivery of air thereinto, a burner assembly 32 carried by the housing and comprising means V3, 61 for supplying liquid waste to the housing, and means V1, 41, for supplying supplemental fuel in close relation to the waste, a rear frustoconical cumbustion chamber 20 connected to the housing, a front frusto-conical chamber 35 in axial alignment with chamber 20, the chambers being separated to provide an air entry space 36, a rear water-spray ring 70, having members 72 for directing water forwardly and inwardly between members 20, 35, and into the flame, and a front water spray ring 73 having members 75 for directing water forwardly and inwardly beyond the front end of member 35 and into the flame. In operation, liquid waste is delivered through pipe 61, through a manifold 55 into an inner burner pipe 52, Fig. 4, and atomizing air or steam is simultaneously delivered through a pipe 58 to a space 57, and thence via openings 54 to provide a foam-like emulsion of the liquid waste as it passes through a convergent nozzle 49- If the combustible content is not sufficient gas is supplied through a pipe 41 and is delivered in surrounding relationship to nozzle 49. The mixture burns with additional air being induced at the spaces 36 between frusto-conical chambers 20, 35, and water is also supplied by pipes 72 and 75, controlled by valves V3, V4, respectively. Two assemblies are carried by support 10 and the structure can be pivoted so as to avoid undesired deflection of the flame by the wind.
