Release of thermal energy during combustion is directly proportional to the amount of oxygen used in this chemical reaction. In a compartment that is completely closed, there is a finite amount of oxygen available. For example, when a burning candle is covered with a glass, the heat release rate is reduced, the flame dims and is eventually extinguished as the oxygen in the glass is consumed.
