Abstract

The invention discloses a methanol fuel self-gasification combustor for an industrial kiln. The methanol fuel self-gasification combustor comprises a combustor body, the combustor body comprises a fuel inlet used for inputting gasified methanol and a combustor nozzle for jetting flames, the methanol fuel self-gasification combustor further comprises a gasification assembly, the combustor nozzle comprises a combustion chamber sleeve pipe used for forming a combustion chamber, the gasification assembly comprises a heat transmitter tightly arranged on the periphery of the combustion chamber sleeve pipe in a sleeving manner, a gasification pipe arranged in the heat transmitter in a winding manner and a PTC electric heating element tightly arranged on the periphery of the gasification pipe in a sleeving manner, and an outlet of the gasification pipe is connected with the fuel inlet through a methanol gas conveying pipe. The whole structure is simple and ingenious, an external special fuel gasification device is not needed, an electric heating gasifier temperature control device is also not needed, and the gasification assembly can control the temperature within the most suitable range for complete gasification of methanol fuel through adjustment.

Description

technical field

[0001] The invention relates to the field of burners, in particular to a methanol fuel self-gasification burner for industrial furnaces. Background technique

[0002] The existing methanol fuel burner is separated from the fuel gasification device, and the installation of the combustion system is relatively complicated. The space installed on some industrial furnaces is limited, which makes it impossible to use the combustion system; due to the separation of the burner and the fuel gasification device, There is a certain distance between the gasification device and the burner. The high-temperature methanol gas after gasification needs to be transported to the burner through metal pipes. When the power of the burner is small, that is, the fuel flow rate is relatively small, the high-temperature methanol gas will As the temperature in the delivery pipeline drops gradually, part of the fuel will condense from liquid phase to liquid phase, which will cause igniti...
