Premise: As noted in Chapter Two, 500 MWe plant firing 4.0 percent sulfur coal and equipped with LSFO FGD technology will use about 32 tons per hour of limestone, or about 240,000 tons/yr (about 0.064 tons/MWh), and limestone consumption for MEL technology would be less.

Hypothesis: The limestone consumption is desired to decrease over the coming years.
Relation: neutral
