Problems solved by technology

Due to the different nature of endothermic and exothermic, and the degree of intensity is uncertain each time, the process is long. In this process, even if the temperature reading of the outer barrel is the same, the heat capacity of the instrument may vary greatly, resulting in a decrease in the accuracy of the test results and poor reproducibility. become worse
Moreover, at present, the inner barrel is generally replenished with water through the spare barrel and the water level gauge. In order to ensure that the temperature of the water medium flowing into the inner barrel is consistent, the method of temperature control in the spare barrel is generally adopted. After the water pump and water level gauge, the temperature of the water changes again before it flows into the inner tub, making it impossible to obtain measurements with high accuracy

It includes internal barrel, external barrel, stand-by barrel and barrel lid placed on the top portion of internal barrel and external barrel. Said invention also provides their assembling mode and working principle of said calorimeter.

Description

technical field [0001] The invention mainly relates to a measuring instrument for measuring the calorific value of coal, oil or other heating substances in coal, petrochemical or electric power industries, in particular to a two-layer peripheral isothermal constant temperature calorimeter. Background technique [0002] In the prior art, the measuring instruments used to determine the calorific value of substances are generally composed of an inner barrel, an outer barrel, and a barrel cover arranged on the top of the inner barrel, wherein the inner barrel is arranged in the outer barrel; when testing, the oxygen bomb and the oxygen bomb of the test sample Place it in the inner barrel, connect it with the ignition electrode, and turn on the electricity to ignite at the specified time, so that the sample can be fully burned. In order to ensure accurate determination of the calorific value of the substance, the temperature of the outer barrel and the inner barrel must be consis...
