Building the Method for Calculation of Heating System Applied to High-Kinematic Viscosity Fuels

Abstract

Environmental pollution in transportation is very serious. Finding alternative fuels is becoming increasingly urgent in order to minimize environmental pollution and diversify fuel sources for marine engines. In alternative fuels, bio-oils are considered as a potential fuel. The paper presents theoritical findings on application of exhaust energy for heating up biodiesel/bio-oil used in ship engines in order to raise the fuel’s viscosity and to improve the volatizing and mixing abilities with ambient air. This fuel heating system is designed basing on the energy balance between the required energy to raise the fuel temperature to the target one and the energy either directly obtained from the exhaust gas or gained from intermediate medium. Results of this study are potentials to direct the design and fabrication of this bio-fuels heating system for ship engines which can meet the operating conditions and safety issues of this kind of engines.
