coal releases : Carbon dioxide as  combustion is occuring with oxygen to produce Co2 (but oxygen isnt released) and it can release sulfur dioxide and notrogen oxide is also produced as the flame of coal is hot enough to form it 

hope that helps 

When burned coal releases carbon dioxide, sulfur, and nitrogen oxide.

Have a great day.
