Liquid fuel gasification combustor

Abstract

The invention relates to industrial or civilian stoves, in particular to a combustor using a liquid fuel. By the combustor, the liquid fuel can be combusted fully. The combustor comprises a fuel inlet pipe for supplying the fuel and a nozzle for spraying the fuel for combustion and is characterized in that: the fuel inlet pipe is connected with a fuel gasifier; the outlet of the gasifier is connected with a gas and liquid separator; and the exhaust port of the gas and liquid separator is connected with the nozzle. In the gasification combustor using the liquid fuel, the gas and liquid separator is arranged creatively, so liquid drops which are not gasified fully can be separated out, the fuel conveyed to the nozzle for combustion is guaranteed to be gaseous and the combustion efficiency is improved greatly. By use of the combustor, the heat efficiency is about 60 percent; compared with the conventional liquid fuel stove, the liquid fuel gasification combustor saves energy by over 50 percent and increases the heating speed by over 30 percent due to the intense fire; furthermore, the liquid fuel gasification combustor avoids environmental pollution caused by fuel volatilization, avoids fuel waste, saves cost and is convenient to use; and social benefits can be obtained.

Description

Technical field [0001] The invention relates to industrial or civil stoves, in particular to burners using liquid fuel. Background technique [0002] Liquid fuels such as kerosene, diesel, methanol, ethanol, etc. In particular, alcohol-based fuels such as methanol and ethanol, which can be made from biological raw materials and have renewable characteristics, may become a substitute for increasingly depleted fossil fuels. Therefore, as a new type of fuel, it has attracted more and more attention from the society. . [0003] However, liquid fuels, especially alcohol-based fuel burners, currently appearing on the market have major drawbacks. Alcohol-based fuel burners on the market mainly include the following types: atomization burners, liquid blast combustion, gasification blast combustion and other types. The working principle of these burners is to use pressure or spray or simultaneous pressure spray to disperse liquid fuel into small droplets or vaporize for combustion. Howe...

AI Technical Summary

Problems solved by technology

But there are disadvantages that cannot be solved, that is, the liquid fuel cannot be guaranteed to be completely vaporized or atomized, so the fuel combustion is not sufficient, and a large amount of fuel is volatilized by heating, which seriously wastes fuel and pollutes the environment; even fuel volatilization or Incomplete combustion will also cause the fuel to decompose and emit toxic and harmful substances

And the combustion flame is unstable, big and small, inconvenient to use

These defects have seriously restricted the use and promotion of alcohol-based fuels
