Abstract
The use of marine engines for energy production is an excellent alternative to meet the instantaneous demand variations because of the possibility of fast starting and its simple and reliable operation. Consequently, several countries utilize this technology to supply the energy demand when other sources are not able to deliver the requested power. During the operations, marine engines consume heavy fuel oil (HFO) due to the low cost and high usage. However, this fuel presents a great viscosity variability, impacting on the power consumption of the auxiliary equipment that prepares the HFO to be injected in the engine, as well as on the main engine performance. The study was developed using a model that quantifies the thermal and electrical energy consumption of the auxiliary equipment and defines, through logical control, the configuration that represents the lower consumption of these machines and the highest global efficiency of the power plant. The auxiliary systems presented a high overall energy efficiency and it was possible to observe scenarios with satisfying results, indicating gains on the usage of controls to adjust the operations based on the viscosity and operational demand.
