Probably two problems. The smoke is most likely oil from an engine problem. The sulfur is the catalytic converter bad. The oil plugs the converter making it run hotter and putting out more sulfur dioxide.

What can cause white smoke from exhaust when heater is on?
I feel these are unrelated but you can investigate a leak in the hoses leading to the heater core as they maybe leaking onto the exhaust pipe, that would produce white smoke, but not from within the tailpipe exhaust. Water and oil leaks will produce white smoke the smell will help you determine which it is.

Why would a 2000 Explorer lose power and the cab fill with smoke and smell of sulfur The manifold was glowing red Is this a Catalytic Converter problem?
It could be running lean. Check the fuel filter. It could also be a vacuum leak or the EGR valve. It would probably be a good idea to not run it much until you've worked out the problem. There are quite a few possibilities, and some of them are not very expensive, but if the exhaust manifold is getting that hot you could be damaging your exhaust valves. If the exhaust manifold is glowing, it's not the cat-converter.
