ABSTRACT:
A heater block assembly for a jet fuel thermal oxidation test apparatus has back and front plates with a test plate clamped therebetween. The test plate has a flat surface which faces the front plate, while the front plate has a raised ledge with a channel formed therein which faces the flat surface of the test plate. Also, inlet and outlet openings to opposite ends of the channel are formed through the front plate. When the back and front plates are clamped together with the test plate therebetween, the flat surface of the test plate and the channel in the front plate together define a fuel sample flow passage. Thus, the fuel sample undergoing test is pumped through the inlet on the front plate into the flow passage where it flows along and in contact with the flat surface and then out through the outlet on the front plate. Electric heating rods disposed in the back plate raise the temperature of the back plate and thereby the test plate and fuel sample, causing thermal decomposition deposits from the heated fuel to form on the flat surface of the test plate.
