    Let's say the barometric pressure determined by a meter is 750 mmHg. To determine what the sensor will calibrate to, divide 750 mmHg by 760 mmHg; this equals 98.68% (750 mmHg / 760 mmHg = 98.68%). At this pressure, saturation cannot be greater than 98.68% as long as water and air are in equilibrium.

  • Combustion Efficiency and Excess Air

    The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Typical excess air to achieve the highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil.
