与常规柴油不同，船用柴油包含一些重质燃料油。
Marine diesel oil contains some heavy fuel oil, unlike regular diesels.
研究开发并完成了一种高效重质燃料油催化燃烧添加剂的工业应用试验。
A high efficient additive was successfully applied to catalyzing combustion of heavy fuel oil in an industrial scale.
但由于重质燃料油与轻柴油在燃油理化特性等方面具有明显差别，在缸内燃烧方面仍然存在许多问题。
Because of much difference in physical and chemical characteristic compared with light diesel oil, heavy diesel fuel makes many problems in fuel combustion on those engines.
重质燃料油一般是原油经过炼制所产生的渣油经调合而成的，主要用作蒸汽锅炉、加热炉以及燃汽轮机的燃料。
Heavy fuel oils that come from residual oils of crude oil refining, are used as fuels of the steam boiler, furnace and gas turbine.
重质燃料油中通常含有一定量的硫及硫化物，燃烧过程中绝大部分形成二氧化硫，二氧化硫在一定条件下与氧化合形成三氧化硫。
The most of sulfur and sulfide that exist in the heavy fuel oils can be transformed into SO2, and SO2 can be oxidized to form SO3 during combustion of heavy fuel oil at certain condition.
