| 235 | Effluent disposal system | US480836 | 1974-06-19 | US3936888A | 1976-02-10 | Paul A. Sturtevant |
| An effluent disposal system for use in conjunction with a high temperature heat source in which waste material is macerate and meterably discharged into the source of heat as a function of heat source operating conditions such as pressure or temperature, thus insuring the most efficient waste disposal throughout the complete heat source operating range. When utilized with an internal combustion engine, the overall system efficiency is increased by obtaining engine operating information from the intake manifold with a sensing means which measures the vacuum or pressure within a particular portion of the intake manifold and uses the intake manifold information as an input to the metering device. Thus, Applicant's device determines the heat source output of an internal combustion engine and relates the engine condition to a metering device for discharging the effluent, thus insuring that the amount of effluent metered into the engine exhaust stream is a function of the engine output. Additionally the effluent discharge line may be placed and housed within the exhaust manifold itself, with the effluent discharge line being constructed of a thermally conductive material to provide effluent discharge into the exhaust line at the maximum heat source, thus insuring the most thorough calcination and sterilization of the effluent. | ||||||
