The biomass energy is solar energy stored in a chemical energy form, has the characteristics of wide distribution, reproducibility and no pollution, and has high-efficiency conversion and clean utilization which are widely regarded. The main utilization mode of biomass as a renewable novel energy source is thermochemical conversion, including pyrolysis, gasification, direct combustion and the like. The byproducts such as tar and the like inevitably generated in the processes not only reduce the utilization rate of biomass resources, but also pollute and damage production equipment and the surrounding environment. However, the research finds that the biomass tar is an excellent liquid fuel and chemical industrial raw material as a pyrolysis byproduct, and the research on the chemical property and the utilization of the biomass tar can achieve the double effects of pollution treatment and resource utilization.
At present, the fuel utilization of tar generally uses tar generated by pyrolysis as fuel for combustion, and uses generated high-temperature flue gas as a heat source to provide heat for front-end pyrolysis equipment. Compared with crude oil, the biomass tar has the defects of high impurity content, high water content, low combustible component content, low heat value, high flash point and the like, so that the problems of difficult tar ignition, unstable combustion of a heating furnace, low combustion efficiency, wear of a burner, coking of an air disc, scaling of a heating surface and the like are caused. The spray combustion is carried out by adopting a pyrolysis tar spraying mode, so that the problem can be better solved. In the atomization combustion process, the quality of the fuel atomization effect is the key for determining the combustion condition. The good atomization effect is the premise of realizing high-efficiency combustion, and has very important significance for energy conservation and purification. Therefore, the components and properties of the biomass tar are analyzed, the tar atomization mechanism is clarified, the spraying characteristics and method are researched, and the mixing process of spraying and air is proved, so that the combustion is reasonably organized, and the method is of great importance for improving the tar combustion efficiency.
