Ember

Glut means the combustion of a largely consisting of carbon fuel with no visible flame, but with the release of light with a high proportion of infrared. Coal burns usually in this form, even during the combustion of wood usually forms embers.

From embers may pose a significant fire hazard as they maintain the combustion process and the associated continuous heat dissipation for long. For large fires, therefore, a fire watch is often for several days off, which is to prevent a resurgence of hot spots.

A useful role embers, however when grilling or campfires, because a lack of open flame for example, prevents a superficial burning of the food. Through the infrared radiation produce hot coals also at a considerable distance still a pleasant warmth.

Deleting a Glutbrandes

Burning embers ( Glutbrand ) is hardly to clear customs by pure oxygen deprivation, since the typically high material density, the ignition temperature remains relatively long. Therefore, the embers must also be cooled and thus the need for the continuation of the combustion heat released therefrom.

Embers of solids is deleted with portable fire extinguishers fire class A, for metal fires with such fire class D.
