High-temperature burner using methanol fuel for ceramic kiln

Abstract

The invention discloses a high-temperature burner using methanol fuel for a ceramic kiln. The high-temperature burner comprises an inlet connecting pipe, an ejector, a premixing pressurizing pipe, an inner fire nozzle, a secondary air introducing pipe, a reversal chamber outer pipe, a burner fire head, a primary air adjusting ring and a secondary air adjusting ring; an inlet of the inlet connecting pipe inputs methanol gas, and an outlet is connected with a methanol gas nozzle; the ejector is in sealed connection with the inlet connecting pipe and is provided with a primary air ejection chamber communicated with the methanol gas nozzle, the primary air ejection chamber is communicated with the outside through a primary air introduction hole, and the primary air ejection chamber extends in the gas outflow direction in a gradually shrinking mode to form an ejector throat part; the premixing pressurizing pipe is in sealed connection with the ejector and is communicated with the ejector throat part, and the gas flowing path of the premixing pressurizing pipe is larger than the ejector throat part; and the inner fire nozzle is connected to an outlet of the premixing pressurizing pipe. According to the high-temperature burner, the size of an air inlet and the air distribution coefficient can be adjusted, burning is sufficient and stable, flame separation, flame lifting and flameout faults are avoided, the phenomena of coking and carbon deposition are avoided, and use is convenient.

Description

technical field [0001] The invention relates to the field of burners, in particular to a high-temperature burner for ceramic kilns using methanol fuel. Background technique [0002] In the existing injection combustion technology scheme of ceramic kiln, the burner can only use natural gas or liquefied petroleum gas. The existing natural gas ceramic kiln burner adopts injection combustion technology. There are: the flame combustion intensity is not enough, the combustion is not Stable, erratic flame, prone to flame separation, easy flameout, high CO content in combustion products, etc., cannot use methanol liquid fuel. Methanol fuel is a liquid fuel with low calorific value. Due to the combustion characteristics, the temperature of the methanol fuel combustion flame is low and unstable when using the traditional atomization combustion technology. Chinese invention application CN111853770A discloses a burner using methanol fuel, which aims to solve the existing methanol fire ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a high-temperature burner for a ceramic kiln using methanol fuel, which at least solves the problem of unstable combustion of the existing methanol high-temperature burner, which is prone to flame separation, flameout and backfire, insufficient combustion intensity, and unable to adjust the size of the air inlet. Air distribution coefficient, the problem of insufficient combustion
