– Why do powerplants require a specific coal type to burn for generating power?

234 views

All I know all coal when burned will generate heat to make steam to make electricity. Can’t they just mix and match or use any type of coal to burn if the specific type is not available?

Probably because the boilers are designed to be very efficient, and therefore have specific requirements for the fuel they use. Things like particle size, contaminants and such almost certainly become important.

You can burn some dirty diesel in an engine, but you might end up with buildup and poor combustion. The same probably goes for coal.
