Abstract

The invention discloses marine fuel oil. The fuel oil comprises the following components in percentage by weight: 45 to 68.0 percent of normal and reduced pressure slag oil, 15 to 30 percent of wax oil, 10 to 13 percent of diesel oil and 7 to 12 percent of oil slurry. The marine fuel oil provided by the invention accords with the work characteristic of a dredging engineering ship, various technical indexes meet the related requirements of national standard and international standard, environmental pollution caused by waste gas discharged by a ship is reduced and a series of problems occurringin the process of using the fuel oil by the dredging engineering ship are avoided.

Description

Technical field [0001] The invention relates to the field of fuel oil, in particular to a marine fuel oil. Background technique [0002] Dredging engineering ships generally operate in port waters around port cities, and the operational reliability of ship power plants directly affects the navigation safety of ports and waterways in the operating waters. And ship emissions put pressure on the urban atmosphere and water environment. Due to the particularity of the dredging engineering ship, its configuration uses medium and high speed diesel engines. Based on the above reasons, marine diesel engines for dredging engineering ships have high requirements for fuel oil quality. In addition to standard physical and chemical properties that need to meet the standard requirements, they are more sensitive to the content of aluminum, silicon, and vanadium in the oil, and have higher requirements for oil sulfur control. . [0003] In recent years, the quality of fuel oil has seriously affe...
