AI Technical Summary

Benefits of technology

This patented technology allows quicker and more accurate measurements on coal during its production than previous methods had been possible due to their limited ability to measure both ash and Volatility (volatile substances). By burning them together under identical temperatures while measuring these properties accurately, there will be less testing error compared to older methods such as laboratory analyses. Additionally, this approach simplifies the entire procedure of determining volatile/ash contents without relying solely upon weightings or other factors like water absorption capacity. Overall, this innovation enhance the accuracy and effectiveness of scientific research into coal quality overcomes disadvantages associated with current techniques used beforehand.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the speed and accuracy with which gaseous substances such as water vapor or other gases found within coal samples may be measured during an automated analyzer's measurement procedure. Current commercial devices require multiple steps before measuring each component separately, making their overall task slow down while requiring more labor than necessary.

specific Embodiment 1

[0049] Specific embodiment 1: when moisture test time>ash content test time;

[0050] 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 sample...

specific Embodiment 2

[0051] Specific embodiment 2: when ash content test time>moisture test time;

[0052] 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 a rapid 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 rapid 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.
