Burner with two coaxial reaction media feed lines

摘要

The burner has two supply lines, an igniter, and a temp. measuring point. The lines pref. run coaxially. Above the outlet (10) from the inner one (1) there is a coiled conical cage (12) with spaces between adjoining windings. A rod (14) accommodating the temp. measuring point (15) runs coaxially with the cage and is supported by the cag apex portion (13). The cage windings form a heater. Pref. they compreise a comprise a protective casing (11) housing an insulated electrically heated wire (16) with PTC end. At least one temp sensor is in the rod's front end section.
