Pulverised Coal - an overview ScienceDirect Topics

Pulverized coal can be used as a reducing agent by injecting it through the tuyeres. Coke has been replaced up to 250 kg/THM with pulverized coal [26]. Coals for PCI are usually cheaper noncoking thermal coals. Important properties of the coals are: • content of volatiles and moisture • chemical composition (S, P, alkalis, ash) •

2017-12-1  Alternative approach is the PC-CGTM1 process, as shown in Fig. 2, whose major components are the AGRU, ASU, MPOU, MSU, and a new pulverized coke gasification unit (PCGU). In the PC-CGTM1, the new PCGU generates CO-dominant syngas, which is mixed with the syngas from the MPOU to adjust the R value to be 2, which is ideal for methanol synthesis.
