What is flame holders?

Flame holders are devices used to stabilize a flame in a combustion system. They play an important role in the efficiency of combustion by controlling the flow and mixing of fuel and air.

There are several types of flame holders, including bluff body, perforated plate, and swirl. Bluff body flame holders use a solid object placed in the flow of the combustion mixture to create turbulence, which helps stabilize the flame. Perforated plate flame holders use a plate with small holes to create a more evenly distributed mixture of fuel and air, which also helps stabilize the flame. Swirl flame holders create a rotating flow pattern that promotes mixing of the fuel and air.

The choice of flame holder depends on the specific application and the desired combustion characteristics. Proper selection and design of flame holders can improve flame stability, reduce emissions, and increase efficiency in combustion systems.
