近年来,船用燃料的质量日趋恶化,其后果是给柴油机带来很多问题. 本文作者仅叙述劣质船用燃料油所引起的燃油加热器问题.研究表明,加热器的燃油侧表面积碳严重,以及导热棘的腐蚀相当明显. 1977年间,燃油侧表面积碳所引起的堵塞故障突然开始增加.最近的资料表明,当船用燃料油中加入燃油添加剂后,积碳问题便显著减少.Sun Rod型燃油加热器导热棘原先以铜为材料时,铜棘上常常发生腐蚀,自从改用铝后,腐蚀现象就很少发生了. 由于船用燃料油的质量将进一步恶化,所以这些问题可能更频繁发生. 为了维修燃油加热器,必须研制一种清除加热表面碳垢的化学去垢剂,这是最重要的.遗憾的是目前市场上没有有效的去垢剂,所以人们对研制这种化学去垢剂的要求十分强烈.
In recent years, the quality of marine fuels has been deteriorating, with the consequence of causing many problems for diesel engines.The author only describes the problem of fuel heaters caused by inferior marine fuel oils.Research shows that the heaters have a large carbon surface area on the fuel side, Spine corrosion is quite noticeable: Sudden increases in clogging due to carbon deposits on the fuel side surface occurred in 1977. Recent data indicate that the problem of carbon deposits is significantly reduced when marine fuel oil is added with fuel additives.Sun Rod fuel heater Thermal conductivity of thorns was originally copper, copper thorns often occur corrosion, since the switch to aluminum, the corrosion rarely occurs, due to the quality of marine fuel oil will further deteriorate, so these problems may occur more frequently. In order to repair Fuel heaters, it is imperative to develop a chemical detergent that removes the carbon surface from heating the surface, but unfortunately there is no effective detergent on the market today, so there is a need to develop such chemical detergents Very strong.
