Burner plate for flat burner has mixture ducts each adjoined on outlet side by cross-sectional expansion so that flame burns therein with reduced specific thermal capacity

摘要

The burner plate used for burning a mixture of gas and oxygen carrier gas has mixture ducts (2) each adjoined on the outlet side by a cross-sectional expansion (3) whose cross-sectional dimensions are greater than the extinguisher interval of combustion so that the flame (5) can burn therein . A cover plate can be provided on the outlet side with openings associated with the cross-sectional expansions. The burner plate or cover plate or burner plate and cover plate can be made from a material of low heat conductivity.
