Weet er iemand welk type kolencentrale ze willen bouwen? CFB of conventioneel?

CFB Technology
Power companies are able to burn the coal that was left behind in gob piles using a technology called Circulating Fluidized Bed (CFB) combustion. CFB boilers use strong jets of hot air to suspend pulverized coal refuse, allowing the coal in it to burn more completely and efficiently than in a conventional coal power plant. The burning fuel creates heat to produce steam, which drives electric generators.

CFB boilers use relatively low temperatures to combust coal, emitting less nitrogen oxide (NOx) pollutants. CFB plants also inject crushed limestone into the boiler, which combines with sulfur in the gob to create an inert solid that is captured to minimize airborne sulfur (SOx) emissions. Using appropriate pollution controls, CFB power plants meet EPA and DEP air quality standards.
