New York-style pizza and New Haven-style pizza are often cooked in coal-fired pizza ovens. A coal-fired oven can reach and cook
Energy value of coal "Q" is a complex function of the elemental composition of the coal. "Q" can be determined experimentally using calorimeters. Dulong suggests the following approximate formula for "Q" when the oxygen content is less than 10%: where "C" is the mass percent of carbon, "H" is the mass percent of hydrogen, "O" is the mass percent of oxygen, and "S" is the mass percent of sulfur in the coal. With these constants, "Q" is given in kilojoules per kilogram. Energy value of coal The energy value of coal, or the fuel content, is the amount of potential energy in coal that
