Buring is, in fact, a chemical reaction. It is a vigorous oxidation process in which hydrogen and carbon atoms in the paper combine with oxygen in the air to become water vapour and carbon dioxide.Because such chemical reaction is exothermic, it produces heat and light.

Yes, as we use a lighter to burn a piece of paper, it produces light energy and the fire is given out, heat energy is produced.
