Liquid fuel gasification device and burner

Abstract

The invention discloses a liquid fuel gasification device, which comprises at least two layers of spiral gasification coils stacked together. Each layer of spiral gasification coils is provided with a fuel inlet and a fuel outlet. In the gasification coil, the fuel outlet of the outer spiral gasification coil is connected to the fuel inlet of the inner spiral gasification coil, and the center of the innermost spiral gasification coil is provided with a gas Heat source for liquefied liquid fuel. The invention also discloses a liquid fuel burner, which comprises the above liquid fuel gasification device and a combustion device. The fuel inlet of the combustion device is connected with the fuel outlet of the innermost spiral gasification coil. The liquid fuel gasification device can not only gasify liquid fuel, but also has the advantages of strong gasification capacity, high gasification efficiency and sufficient gasification, and solves the problem of carbon blockage in the gasification process; the liquid fuel burner has a combustion The advantages of good effect and high combustion efficiency can be suitable for industrial applications.

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 ...
