Upper air inlet furnace end capable of adjusting air intake

Abstract

The invention provides an upper air inlet furnace end capable of adjusting the air intake. The upper air inlet furnace end comprises a furnace end lower part, a furnace end upper part arranged on thefurnace end lower part and nozzles. Multiple air inlet pipelines and multiple air seats communicated with the air inlet pipelines are arranged on the furnace end lower part. The double nozzles are arranged on each air seat. An air conditioning part is arranged at one end of each nozzle. Multiple outwardly-extending ejection bridges connected with the air seats are arranged on the furnace end upperpart. Air inlet ends are arranged below the ejection bridges. Center air channels corresponding to the corresponding double nozzles and outer ring air channels are arranged on the ejection bridges. The outer ring air channels are communicated with an outer ring air mixing cavity in the furnace end upper part. The center air channels are communicated with an inner ring air mixing cavity in the furnace end upper part. By forming a spiral air flow, the air mixing effect is improved, meanwhile the air combustion efficiency is improved, the air inlet ends are formed below the ejection bridges, sufficient air is provided for the furnace end upper part in multiple directions, the occurrence of red flames is prevented, and the air intake can be adjusted at the nozzles to prevent unstable flames.

Description

technical field [0001] The invention relates to an upper air intake furnace head capable of adjusting air intake. Background technique [0002] The traditional upward air intake burner is easy to cause off-flame or red inflammation due to unstable gas source during use. However, due to the structural limitations of the upward intake air burner, users need to disassemble the burner to adjust the air intake, and some even adjust it. No, this brings great inconvenience to users. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide an upper air intake burner head with adjustable air intake, which adopts multiple groups of nozzles to transport gas to the injection bridge to form a spiral air flow, so as to improve the gas and air intake. The air mixing effect improves the efficiency of the gas at the same time. The air intake end is formed under the ejection bridge, and sufficient air is provided t...
