Liquid fuel gasification device and liquid fuel burner

Abstract

The invention discloses a liquid fuel gasification device. The device comprises at least two layers of spiral gasification coil pipes which are sleeved together in a laminating mode, wherein each spiral gasification coil pipe layer is provided with both a fuel inlet and a fuel outlet, in the adjacent two layers of the spiral gasification coil pipes, a fuel outlet of a spiral gasification coil pipe which is located in an outer layer is connected with a fuel inlet of a spiral gasification coil pipe which is located in an inner layer, and a heat source which is used for gasifying the liquid fuel is arranged in the center of a spiral gasification coil pipe which is located in the innermost layer. The invention also discloses a liquid fuel burner. The burner comprises the liquid fuel gasification device and a burning device, wherein a fuel inlet of the burning device is connected with a fuel outlet of the spiral gasification coil pipe which is located in the innermost layer. The liquid fuel gasification device can gasify the liquid fuel and has the advantages of being high in gasifying capacity and gasifying efficiency and being gasified fully, and the problem of carbon blockage during gasification is solved. The liquid fuel burner has the advantages of good in burning effect, high in burning efficiency and suitability for industrial application.

Description

technical field [0001] The invention belongs to the technical field of burners, in particular to a liquid fuel gasification device capable of gasifying liquid fuel and a liquid fuel burner using the liquid fuel gasification device. Background technique [0002] Alcohol-based liquid fuel is a low calorific value liquid fuel. Its combustion methods include liquid surface direct combustion, liquid spray combustion and liquid gasification combustion. For low calorific value liquid fuels, the flame effects of liquid surface direct combustion or liquid spray combustion are both It is very poor, and basically cannot meet the combustion requirements of industrial furnaces. Although the combustion effect of liquid gasification combustion is good and the efficiency is high, the gasification technology of liquid fuel is a difficult problem. [0003] Although the currently used liquid fuel vaporizers can achieve gasification and combustion of liquid fuels to a certain extent, there are ...
