A large number of companies world-wide have to rely on captive Power generation where they use Heavy Fuel Oil Engines. This segment is mostly dominated by two players, Wartsila and MAN, and incidentally both the companies had been extremely pro-active in adopting and endorsing Emulsified Fuels, starting with the erstwhile Orimulsion. Usage of Emulsified Heavy Fuel Oil in such HFO engines, whether for power generation or marine application not only results in better fuel economy, combustion and lower emission but also cuts down on centrifuging losses and extends engine life by providing lean burn conditions, but with no increase in temperature.
