ABSTRACT:
An apparatus for the preheating of liquid waste having a heated sealed container, a liquid waste tank, a jacket positioned around the sealed container so as to form a heat exchange region between the interior of the jacket and the exterior of the sealed container, and an injector for transmitting a heated liquid waste from the tank into the interior of the sealed container. An inert gas container is connected to the waste tank so as to pass argon gas for displacing the oxygen from the interior of the liquid waste tank. An insulating layer is formed around the exterior of the sealed container and the waste tank. Suitable conduits connect the waste tank with the heat exchange region of the sealed container. A storage vessel is in valved relationship with the liquid waste tank. Suitable pumping is provided so as to transmit the liquid waste into the heat exchange region and back to the liquid waste tank.
