沥青拌和楼用柴油改重油,可以通过将柴油燃烧器换成能烧重油的燃烧器来实现,另外需要增加的设备和装置有燃烧器控制电柜、空气压缩机、储气罐、带导热油加热的重油罐以及一些管材等辅料。选择重油燃烧器时,要考察其是否能燃烧高标号重油或渣油,还要重点考察所选用的燃烧器与拌和楼的除尘器、引风机等部件的匹配性。对5台沥青拌和楼进行了柴油改重油改造,改造后每生产1t沥青砼可节约的燃油成本为10.3元,初期设备改造投资费用216万元,预计生产21万t的沥青砼可收回改造投资费用。
Asphalt mixing plant with diesel to heavy oil, can be replaced by diesel burners can be burned heavy oil burner to achieve, in addition to the need for additional equipment and burner control cabinet, air compressor, gas tank, with HTF Heated heavy oil tank and some pipe materials. When choosing a heavy oil burner, it is necessary to investigate whether it can burn high-grade heavy oil or residual oil, but also to investigate the matching between the selected burner and mixing plant dust collector, induced draft fan and other components. Diesel oil reforming was carried out on 5 asphalt mixing plants. The cost of fuel saved per 1 ton of asphalt concrete after transformation was 10.3 yuan and the initial equipment investment cost was 2.16 million yuan. It is estimated that 210,000 tons of asphalt concrete can be recovered for investment cost.
