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...
