specific Embodiment 1

[0050] Specific embodiment 1: when moisture test time > ash content test time;

[0051] The test process is as follows: the instrument is turned on stably, reset, the high and low temperature furnaces are raised to the set temperature; 6 moisture air-dried coal samples are weighed in the normal temperature zone (the number in the scheme is for illustration only, not limited to this number), and the The sample mechanism is sent to the low-temperature furnace for drying; 6 ash air-dried coal samples are weighed in the normal temperature zone, and sent to the high-temperature furnace for burning through the sample feeding mechanism, and the damper is opened at this time; the volatile air-dried coal samples are weighed in the normal temperature zone 6 samples, close the damper of the high-temperature furnace; send the volatile air-dried coal samples into the high-temperature furnace for heating; at this time, there are 6 ash air-dried coal samples and 6 volatile air-dried coal samp...

specific Embodiment 2

[0052] Specific embodiment 2: when ash content test time>moisture test time;

[0053] The test process is as follows: the instrument is turned on stably, reset, the high and low temperature furnaces are raised to the set temperature; 6 ash air-dried coal samples are weighed in the normal temperature zone (the number of examples in the scheme is for illustration only, not limited to this number); at this time The damper of the high-temperature furnace is opened; the ash air-dried coal sample is sent to the high-temperature furnace by the sampling mechanism for burning; 6 moisture air-dried coal samples are weighed in the normal temperature zone, and sent to the low-temperature furnace for drying through the sampling mechanism; Weigh 6 volatile air-dried coal samples; close the high-temperature furnace air door; send volatile air-dried coal samples into the high-temperature furnace for heating; at this time, there are 6 ash air-dried coal samples and 6 ash air-dried coal samples ...

Abstract

Disclosed is an industrial analysis method for coals, which gets a moisture value, an ash value, a volatile value and a fixed carbon value in a coal sample after carrying out a moisture test, an ash test and a volatile test on the coal sample; the method carries out a test on an ash air-dried coal sample and a volatile air-dried coal sample at the same time in an identical high temperature furnace to get the ash value and the volatile value. The invention is the industrial analysis method which has the advantages of short test time, high work efficiency and accurate test results, as well as can satisfy the rapid on-line analysis requirements for an industrial field.

Description

technical field [0001] The invention mainly relates to the field of industrial analysis and measurement of coal, in particular to an industrial analysis method of coal. Background technique [0002] Industrial analysis of coal usually includes the analysis and testing of the four values ​​of moisture, ash, volatile matter and fixed carbon in air-dried coal samples. Among them, the moisture, ash, and volatile content are all obtained through the test data calculation results, and the fixed carbon is obtained through calculation using the above three test results, that is, the conventional industrial analysis test should have at least the above three test processes, and the air drying process can be obtained. The industrial analysis of the air-dried coal sample is completed after the moisture, ash, volatile matter and fixed carbon values ​​in the coal sample are calculated. With the advent of automatic industrial analyzers, automatic weighing, automatic loading and unloading ...
