What is the term used for heat in the combustion chamber that maintains the fire after ignition is turned off?

The term that refers to the heat in the combustion chamber that continues to maintain the fire after the ignition has been turned off is known as residual heat. This is the heat that remains in the combustion chamber and can sustain the combustion process for a period, even in the absence of continuous ignition. This effect is particularly important in oil burner operations, as it allows for a more efficient use of fuel and helps ensure that the fire remains stable.

Residual heat minimizes fluctuations in temperature and promotes a consistent burn, contributing to the overall efficiency of the heating system. It is a key concept in understanding how combustion systems operate and the role of thermal properties in maintaining a stable flame. This understanding helps operators manage and optimize burner performance effectively.
