Abstract

The invention discloses a method for measuring volatile components of coal and an application. The method comprises the following steps: 1) breaking test coal and sieving; 2) weighing a coal sample of set mass, heating and drying to constant mass, and putting the dried coal sample in a dry environment; 3) weighing a moisture content measuring test coal sample of set mass from the coal sample dried in the step 2), heating and drying the moisture content measuring test coal sample, and measuring the moisture content; 4) weighing a volatile component content measuring test coal sample of set mass from the coal sample dried in the step 2), and performing a volatile component content measuring test to measure the weight loss of the coal sample, wherein the ratio of the mass of the moisture content measuring test coal sample and the volatile component content measuring test coal to the sampled mass of the coal sample in the step 2) is 1:(3-20); and 5) calculating the volatile components in the coal sample according to the weight loss and moisture content of the coal sample.

Description

technical field

[0001] The invention belongs to the field of thermal power generation, in particular to a method for measuring volatile content of coal and its application. Background technique

[0002] The volatile content of coal is closely related to the quality of coal; according to the volatile content, the characteristics of the coke block after the volatile content are measured, which provides a reference basis for the preliminary decision on the processing and utilization of coal; in the process of coal blending and coking , it is necessary to use volatile matter to determine the proportion of coal blending; to estimate the yield of coke, gas and tar according to volatile matter; volatile matter also plays an important role in gasification and liquefaction processes, and can provide Good for reference purposes; volatiles also play an important role in calculating calorific value and hydrocarbon content. The determination of volatile matter is an important detection ...
