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 .
MEL technology provides more limestone consumption than LSFO FGD technology .
