Thermal analogue electric furnace for use in researches on hydrocarbon generation kinetics

Abstract

The invention discloses a thermal analogue electric furnace for use in researches on hydrocarbon generation kinetics, which comprises a furnace body (1). A hearth (2) of the furnace body is a cylindrical cavity, the center of the hearth is provided with an annular heating barrel (3), the hearth is provided with at least two high pressure kettles (4) which are arranged vertically, and the high pressure kettles are annularly distributed around the heating barrel; the top of the furnace body is provided with a high pressure kettle sampling aperture (5) corresponding to each high pressure kettle, the top of the high pressure kettle is connected with a high pressure water pipe (6) which is introduced inside through the high pressure kettle sampling aperture, and the inside of the high pressure kettle sampling aperture is provided with a plunger piston (7); and the inside of the heating barrel is provided with a fan (8), the fan is connected with a motor (9) which is arranged at outside the furnace body, and the furnace body is provided with an electric thermo-couple (10) for measuring the air temperature in the hearth and an electric thermo-couple (11) for measuring the air temperature in the high pressure kettle (4). The thermal analogue electric furnace has a requirement on uniformity of heating temperature in the furnace and the temperature difference between the high pressure kettles is less than 1 DEG C.

Description

technical field [0001] The invention relates to an electric furnace for heating, in particular to a thermal simulation electric furnace used for the study of hydrocarbon generation kinetics. Background technique [0002] Hydrocarbon generation kinetics is an important method in oil and gas research. In the study of hydrocarbon generation kinetics, natural organic matter samples need to be packaged in gold tubes, and each gold tube is placed in an autoclave, and multiple (usually 10) autoclaves equipped with gold tubes are placed in a thermal simulation electric furnace In the process, the electric furnace is gradually heated up according to a certain program. When a certain temperature is reached, the corresponding autoclave is taken out from the furnace, and the remaining autoclaves continue to be heated, and so on, until the end of the experiment. In the above test, the most important requirement for the electric furnace is: the temperature of each position in the furnace...

AI Technical Summary

Problems solved by technology

At present, there are no suitable electric furnaces for sale at home and abroad. The equipment made by individual foreign research institutions are all modified with square box-type electric furnaces. Because the temperature difference in each position in the box-type electric furnace is large (up to 10 ℃), each The autoclave must be equipped with a temperature measuring thermocouple, the structure is very complicated and the effect is not good
