     · Much of the boiler slag currently produced is from cyclone boilers which are falling out of favor due to high NO X emissions. As older cyclone boilers are retired the amount of available boiler slag will decrease. For example 2.57 million tons of boiler slag were produced in 1996 (NETL 2006) compared to 2.03 million in 2006 (ACAA 2007).
