Example Embodiment
[0022] Example 1:
[0023] (1) According to the national standard method, the thickness of the colloidal layer of Shenmu Long Flame Coal (SMC), Wuhai Gas Coal (QM-1) and Taiyuan Fatty Coal (FM-1) was determined to be 0, 11 and 32 respectively;
[0024] (2) According to the additivity of the Y value of a single coal, first formulate the ratio of a single coal when the Y value of the coal is greater than 10; The proportions of coal and fat coal are 40wt%, 35wt% and 25wt% respectively;
[0025] (3) The single coal is pulverized respectively. In terms of weight percentage, the particle size distribution of SMC is 25% in the proportion of <1mm, 25% in the proportion of 1-2mm, and 50% in the proportion of 2-3mm; the particle size distribution of QM-1 is <1mm scale 15%, 1-2mm scale 30%, 2-3mm scale 55%. The particle size distribution of FM-1 is <0.2mm and the proportion is more than 90%
[0026] (4), mix the coal of different granularity, and add moisture 10wt%;
[0027] (5) Afte...
Example Embodiment
[0029] Example 2:
[0030] The thickness of the colloid layer of Pingshuo long flame coal (PSC), Wuhai gas coal (QM-1) and Wuhai fat coal (FM-2) used in this example are 0, 11, and 33, respectively. They are 40wt%, 35wt%, and 25wt%, respectively. The particle size distribution of PSC is 3 , the heating rate is 5°C / min, and the amount of water added is 9wt%. The Y value of its blended coal, coke strength and reactivity index are shown in Table 1. The rest are the same as in Example 1.
Example Embodiment
[0031] Example 3:
[0032] The thickness of the colloidal layer of Shenmu Long Flame Coal (SMC), Shenmu Gas Coal (QM-2), and Wuhai Fei Coal (FM-2) used in this embodiment are 0, 12, and 33, respectively. 40wt%, 35wt%, 25wt%. The particle size distribution of SMC is 3 , the heating rate is 4°C / min, and the amount of water added is 11wt%. The Y value of its blended coal, coke strength and reactivity index are shown in Table 1. The rest are the same as in Example 1.
