Tiande Brand methanol-based fuel oil additive/surfactant is a highly active compound fuel additive: it is through interaction between high cetane fused ring compound and substances with higher oxygen content to release high energy of fused ring compound. Adding it into methanol at certain ratio, Tiande Brand methanol-based fuel oil additive/surfactant can release its energy completely. Heat value of its finished product—methanol-based blended fuel is over 9000 kilocalories. For its high heat value property, it is a good selected product being as boiler fuel applied in all industries such as aluminum plant, ceramics plant, industrial boilers and manufacturing industry without changing any part of boiler's combustion engines. It has good economic benefits and it could save 45% energy compared with diesel. Tiande Brand methanol-based blended fuel enhances lubrication effect on parts of oil pumps, fuel injection nozzles and valves so it has function of extreme resistance to abrasion. It also reduces and controls the acidification phenomena during burning process of fuel so it has functions of anti-corrosion and anti-rust. Using this product on a long-term basis can maintain the clean of the whole oil pipes and fuel injection system, and effectively control and reduce oil sludge so it can protect the whole fuel system and prolong the use time of equipment.
