The Crystal Coal Infuser is the last step in the coal enrichment process. By putting Enriched Coal into the machine and supplying it with 0.1 PPS it will turn it into Infused Coal. Infused Coal burns for 4 times the amount of PPS in a Pyrothermic Generator. It takes 15 seconds for the machine to make Infused Coal allowing a 1:1 ratio between Coal Enrichers and Crystal Coal Infusers and a 1:2 ratio between Crystal Coal Infusers and Pyrothermic Generators.
