A curmudgeon with years of practice.
Burning coal requires oxygen to chemically react (C+O2=CO2). The availability of oxygen is limited in the furnace by several factors such as the friction of the air against the coal. Blowing provides more oxygen to the flame and raises the temperature of the flame. The hotter flame pops the corn more rapidly. Blacksmiths use the same principle to raise the temperature of their forges.
