[Stoves] Burning coal in cookstoves

[Tom Miles]

Philip,

We were co-firing wood with coal at a prison. The inmates working at the
boiler house pointed out that the sulfur smell had disappeared from the
stack and the ash was a lot cooler and more friable to work with. Sulfur
capture was confirmed by emissions and ash tests.
