Furnace end structure capable of avoiding coking

Abstract

The invention provides a furnace end structure capable of avoiding coking. The furnace end structure is characterized in that a furnace end inner container is arranged in a furnace end shell, a cavity formed between the outer side wall of the furnace end inner container and the inner side wall of the furnace end shell is a combustion-supporting chamber, and the combustion-supporting chamber communicates with an air inlet pipe; air holes are formed in the side wall of the furnace end inner container, and the furnace end inner container communicates with the combustion-supporting chamber; a first fuel through hole and a second fuel through hole are formed in the bottom of the furnace end inner container and the bottom of the furnace end shell respectively, a gap surrounding a spray head by a circle is formed between the spray head and the second fuel through hole, and fuel sprayed out of the spray head enters the furnace end inner container through the first fuel through hole and the second fuel through hole; and the spray head is connected with the furnace end shell through a fixing piece. The spray head is separated from the furnace end inner container and the furnace end shell, so that the spray head is not in contact with the furnace end inner container and the furnace end shell; and after the furnace end structure is used, high temperature on the furnace end inner container and the furnace end shell cannot be conducted to the spray head, meanwhile, fuel located in the spray head and on the surface of the spray head cannot be catalyzed by the high temperature, and the problem that the spray head is coked and blocked is avoided.

Description

technical field [0001] The invention relates to the field of burner structures, in particular to a burner structure for avoiding coking. Background technique [0002] The stove head is the core component of the stove burner, its quality affects the performance of the whole stove burner, and after the burner is used for a long time, the inside and surface of the nozzle are easy to coke, which will affect the use effect and service life of the stove head. In the existing burner head structure, the inner tank is sleeved on the nozzle through the combustion through hole on the shell; Fuel remains on the surface of the nozzle and inside the nozzle, and it is easy to coke and block the nozzle under high-temperature catalysis. Contents of the invention [0003] For this reason, it is necessary to provide a furnace head structure that avoids coking, so as to avoid coking and clogging of the nozzle. [0004] In order to achieve the above purpose, the application provides a burner...
