A laboratory-based biomass liquid fuel atomization evaporation combustion system and method thereof

Abstract

The invention relates to a biomass liquid fuel atomization and evaporation combustion system used based on a lab and a method of the system and belongs to the technical field of energy and environment. The system comprises a fuel system, a gas supply system, a carrier gas system, an atomization and evaporation system and a combustor, wherein the fuel system is used for heating vegetable fat or bio-oil and introducing to the atomization and evaporation system; heating air provided by the gas supply system is used for preheating the atomization and evaporation system; air and oxygen mixed gas provided by the air supply system is used for providing combustion supporting gas for the combustor; after temperature is increased and pressure is adjusted, air or inert gas in the carrier gas system is introduced to the atomization and evaporation system so as to transform the vegetable fat or bio-oil into gases; and the gases are introduced to the combustor and are combusted under the support of the combustion supporting gas. The system and the method provided by the invention can solve the problems of relatively large atomization particles, incomplete combustion, relatively low thermal efficiency and the like of the vegetable fat and bio-oil, and can also be used for doing researches on flame combustion characteristics and exhaust characteristics in the lab.

Description

technical field [0001] The invention relates to a laboratory-based biomass liquid fuel atomization evaporation combustion system and a method thereof, which belong to the technical field of energy and environment. Background technique [0002] With the rapid development of industry, the demand for fuel is increasing. At this stage, in the process of fuel combustion, energy saving, emission reduction, operation cost reduction, and combustion efficiency improvement have become the keys to long-term research and urgent solutions in many countries. sexual issues. Fossil fuels such as coal and petroleum and fuels such as industrial gas currently used in many countries are non-renewable energy sources. At the same time, these fuels contain high sulfur elements, and the emitted particulate matter and SO X Cause air and environmental pollution, and energy consumption is higher. In order to alleviate the energy crisis, reduce environmental pollution and achieve sustainable social d...

AI Technical Summary

Problems solved by technology

In this method, the refined vegetable oil or bio-oil is used as the combustion agent, and the high-temperature inert gas or air is used as the atomized evaporation medium. The air is fully mixed, and the oil and gas are sent to the burner. The hot air or the mixture of air and oxygen is sent from the outer circular sleeve, and the high-temperature and high-pressure oil and gas are sprayed to the external environment through the circular nozzle under the protection of the combustion-supporting gas. Combustion, solve the problems of large atomized particles of vegetable oil and bio-oil, incomplete combustion, low thermal efficiency, etc., and can conduct research on flame combustion characteristics and emission characteristics in the laboratory
