Research on Zhundong coal's ash melting temperature characterizing its slagging characteristics

The ash melting temperature of Zhundong coal greatly contradicts with its slagging characteristics. This paper investigates the reasons behind the poor correlation by resolving the raw coal and its ash prepared under the GB / T 212—2008 standard with microwave digestion technology( the ash obtained through this method is called standard ash in this paper). The test results lead to and confirm the following conclusions: all the main metallic...
