Description

Injection head structure of combustor Technical Field The utility model relates to a jet head structure of a burner, and belongs to the field of burners. Background The flame temperature of the jet head is extremely high, and the ambient temperature around the jet head rises sharply during the continuous operation. Since the spray heads are typically mounted on a specific support carrier, these support carrier surfaces are often coated with paint for protection, aesthetics, etc. But the high temperatures generated by the flame can cause severe damage to the paint surface supporting the surface of the carrier. The high temperature causes the organic components in the paint surface to generate chemical reactions such as thermal decomposition, oxidation and the like, so that the paint surface changes color, bubbles, falls off and the like. The paint surface damage not only affects the appearance of the support carrier, but also reduces the protective performance of the support carrier, so that the support carrier is easy to be damaged by corrosion, abrasion and the like, the service life of the support carrier is further shortened, the equipment maintenance cost is increased, and even the normal operation and the safety of the whole equipment can be affected when serious.
