磁场作用下乳化重油稳定性的实验研究

燃油磁化燃烧技术是一种新的燃烧技术 ,目前以日本发展较快1,2 ] ,其节能效果也已为实践所证实3～ 5] 。我们知道 ,掺水乳化重油稳定性好 ,燃烧状况就稳定 ;稳定性差 ,油水在进入炉膛燃烧前就已分层 ,不但起不到“微爆”效果 ,而且严重时导致熄火。作者曾对未磁化乳化重油的粘度、稳定性和分散度进行了实验研究6～ 8] ,丘纪华等学者9～ 11] 对磁化技术在石油、化工、燃料等方面的作用机理及应用进行了一定的研究 ,但是重油掺水乳化后再经磁化处理后其稳定性发生怎样的变化 ,尚未见实验报道。因此 ,为了更好地发挥这一技术的节油和环保效…

EXPERIMENTAL STUDY OF THE STABILITY OF EMULSIFIED HEAVY OIL (EHO) UNDER MAGNETIZATION

The stability of emulsified heavy oil(EHO) has a significant effect on the combustion of water in heavy oil emulsion Based on the prior experimental studies, the influential factors are studied systematically before/after magnetization in various experimental conditions It is found that the stability of EHO is related to fuel type, the percentage of water added in oil(PWA) , Emulsifier added in oil(PEA),magnetic strength and the tube material The following results are obtained: the stability of EHO decreases as the increase of PWA and the decrease of PEA before/after magnetization; in the same experimental conditions, the stability of EHO becomes better after magnetization, when PWA varies in the range from 7 5% to 12 5% and, PEA being bigger than 0 03%, there is a better stability; No 100,No 200 and CL 1 oil has the different stability, the order is No 100>No 200>CL 1; the higher the magnetic strength, the better the stability of EHO; in view of energy consumption and the stability, the rational value of magnetic strength is from 1?200?GS to 1?400?GS; using stainless steel tube has a better effect on stability than using iron tube
