1.INTRODUCTION

        The dual-fuel power plants are based on engines that are able to run on natural gas,diesel oil or light oil, heavy fuel oil (HFO)or a number of other liquid fuels, offering the ultimate in fuel flexibility.

        The ability to switch to the most economical, or available, fuel is of great value in a time of fluctuating fuel prices. Furthermore, the fuel can be switched whilst the engine is operating, for example if the gas supply is interrupted due to the emergency condition happened,which can be running by the fuel oil according to the designing. This operational flexibility is a big advantage with the dual-fuel system.
