GB/T 39836-2021 Translated English of Chinese Standard. (GBT 39836-2021, GB/T39836-2021, GBT39836-2021): Test methods for slagging indexes in coal combustionhttps://www.chinesestandard.net, 2021. 4. 17. - 17페이지 This document specifies the determination method, test device, test instrument and method, data processing and calculation method for slagging indexes in coal combustion. This document is applicable to the determination for slagging indexes of power coal products such as power station boilers and industrial boilers. Applicable coal types are lignite, bituminous coal and anthracite (excluding coal with a total content of Na2O and K2O greater than 3% in coal ash). |
