The boiler fuel oil containing industrial fusel is characterized in that: the material is prepared from the following raw materials in percentage by mass: 70-80 parts of industrial fusel, 20-30 parts of durene, 2-5 parts of butanone, 2-4 parts of castor oil and ethylene oxide condensation compound,3-6 parts of tween, 2-4 parts of nonylphenol polyoxyethylene ether, 3-8 parts of silane coupling agent and Na2O25-10 parts;
the preparation method of the boiler fuel oil containing the industrial fusel comprises the following steps:
(1) filtering industrial fusel to remove upper-layer floating substances;
(2) standing and settling the fusel obtained in the step (1) to discharge the water at the lower part;
(3) adding aluminum borate into the industrial fusel obtained in the step (2) according to the alcohol-acid ratio of 1:0.0005-1:0.005, stirring for 30-50min, precipitating, and discharging acid residues; then adding Na2CO3Neutralizing, precipitating and removing residues;
(4) putting the industrial fusel obtained in the step (3) into a funnel filled with quartz sand for filtering, and further removing impurities;
(5) weighing the industrial fusel obtained in the step (4), durene and butanone according to the mass ratio, and fully mixing the industrial fusel, the durene and the butanone under the stirring condition;
(6) sequentially mixing castor oil, an ethylene oxide condensate, tween, nonylphenol polyoxyethylene ether, a silane coupling agent and Na according to the mass ratio2O2And (5) adding the mixture obtained in the step (5), and stirring for 30-50min to obtain the boiler fuel oil.
