The invention discloses a calorimeter and an oxygen bomb thereof. The oxygen bomb comprises: a bomb cylinder; a detachable bomb cover in sealing fit with the bomb cylinder; a support fixed in the bomb cylinder; a container arranged on the support and used for containing a sample; a light emitter fixed in the bomb cylinder; a focalizer fixed in the bomb cylinder and provided with a condensing mirror, wherein the condensing mirror faces lights emitted by the light emitter, and the focalizer can focus the lights emitted by the light emitter to the sample in the container; and a conductive member electrically connected with the light emitter. When the oxygen bomb is used to ignite the sample to be measured, only the light emitter is electrified to emit lights without replacing cotton threads or metal wires, so simple operation and no tediousness are realized. Calculation of the residual heat of the metal wires is not needed, so the workload of heat measurement is reduced. Cleaning of the residual metal wires is omitted, so the cleaning work is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of calorimetry, and more specifically relates to a calorimeter and an oxygen bomb thereof. Background technique [0002] The calorific value of coal is an important indicator for judging the quality of coal, and it is also an indispensable pricing indicator for coal trading. The calorific value of coal is generally measured using a calorimeter. [0003] The structure of the calorimeter includes an oxygen bomb, a shell, a stirrer, and an auxiliary machine that provides constant temperature water. The coal sample is fully burned in the oxygen bomb, that is, there is a sufficient amount of oxygen in the oxygen bomb, and the coal sample to be tested is placed in the oxygen bomb for full combustion. During the combustion process, the oxygen bomb is placed in the water, and then the change of the water temperature before and after the coal sample to be tested is measured, and then the calorific value of the coal...
