Admiralty fuel oil is a widely used fuel oil with large heat, good combustibility, stable storage and small corrosivity. Because of its low viscosity and freezing point, it can be used with slightly preheating or without preheating.this product has small corrosivity and high flash point with good qualities of flowability in the low temperature, combustibility, volatility and storage. It can decrease the emission of PM2.5 and reduce the environmental pollution because it contains less ash and carbon residue.
