    摘要: An apparatus for determining the thermal stability of fluids, particularly for testing the deposition characteristics of fuels, comprising a conduit system which connects in series; a reservoir to contain fresh fluid having within it a movable piston capable of discharging the fluid, a heater tube housing in which is mounted a heated tubular member, a time reactor housing of a sufficient volume to decrease the flow of the fluid therethrough, a spent fluid reservoir, a filter located at an outlet of the heater tube housing designed to trap deposits which may be formed due to the heating and remain suspended in the fluid, a similar filter located at an outlet of the time reactor housing designed to trap further deposits that may form with additional time, a differential pressure measuring device connected across each of these filters to measure the pressure drop therethrough, and a valved bypass around each of these filters. The apparatus also contains a water balanced reservoir and pressure regulator whereby the entire system may be maintained at a constant pressure and not discharge volatile organic fuels to the outside.
