No, Lignite burners had a overhanging look since the smokebox was extended. The
extension was the entire smokebox, whereas coffin FWH form an arch when
installed
and look more like a huge eyebrow. The extensions contained extra screening
since
Lignite (i.e. Sub-Bituminous) coal has far less BTU's per weight than bituminous
resulting in much more ash being created when burned. You can tell by looking at
locomotives in the same class and see the overhang.
