煤質化驗設備/煤質分析設備化驗流程!

2019-04-16 11:33:13??????點擊:
煤質化驗設備/煤質分析設備化驗流程大體為:

采樣——破碎——干燥——制樣——實驗分析

煤質化驗設備/煤質分析設備化驗流程具體步驟為:

1 原煤采樣:根據原煤存放方式依據國標采樣,工具自備

2破碎:用破碎機破碎采樣煤樣粒度在6mm以下,供3使用

3干燥:用干燥箱依據國標干燥出制樣煤樣,并且做出全水分值(需要500克稱重器具自備),

4制樣:用制樣機把干燥過的煤樣制成粒度為0.2mm的分析煤樣,供分析實驗用

5分析實驗:全部分析實驗用電子天平稱重

分析水(內水):用干燥箱做出

灰分,揮發分:用馬弗爐做出

硫:用測硫儀做出

發熱量:用量熱儀做出

煤質化驗設備/煤質分析設備化驗流程備注:準確的發熱量結果需要煤中的含硫值
