渣油是常压重油减压分馏后的残油,其粘度大(80℃运动粘度为350 x 10~(-6)～650×10~(-6)m~2/s),沥青及氧化性胶质含量高(约为30％～50％),碳氢比大(7.0～7.5之间)。作为燃料的主要缺点是充分雾化困难,燃烧效率低,烟尘发生量大,易冒黑烟和易发生燃烧故障。乳化燃烧作为节能减污新技术,国内外许多资料都有报道。近年来,国内许多单位试验了重油乳化燃烧法,已见报道的加水量在8％以下,节能减污效果不明显,而渣油的乳化燃烧还未见报道。在近一年的时间 Residue is the residual oil after decompression fractionation of atmospheric heavy oil, its viscosity is high (kinematic viscosity at 80 ℃ is 350 × 10 -6 -650 × 10 -6 m -2 / s), asphalt and oxidation High colloidal content (about 30% to 50%), large hydrocarbon ratio (7.0 ~ 7.5). The main drawbacks as a fuel is full atomization difficulties, low combustion efficiency, large quantities of soot, easy to smoke and prone to combustion failure. Emulsion combustion as a new energy-saving technology, many domestic and foreign reports have been reported. In recent years, many domestic units tested the heavy oil emulsification combustion method. The reported addition of water is less than 8%, and the effect of energy-saving and pollution-reduction is not obvious. The emulsification and combustion of residue have not been reported yet. In nearly a year’s time
