Abstract
A carbon powder containing small molecules about 10-20 micrometers dissolved in water is a good fuel for applying in large power diesel engines in electrical plants. Aqueous emulsion of coal has possibility of well cooling of injectors and has a good lubricity. This technology starts in Japan, USA and Australia as additional local source of generators' drive. The paper gives information about obtaining of the mixture, its physical properties and technical realization of the fuelling system. The main part of the paper presents thermochemistry of the combustion process with additional aspects of possible gasification and explains the combustion processes taking place in the cylinder during combustion process. The thermodynamic parameters of the fuel injection and combustion process are presented in the graphs on the basis of CFD calculations worked out in Fluent program and compared with those obtained also from calculations for CI engine fuelled by diesel oil. The possible gasification reactions enable obtaining additional amount of hydrogen. The paper is a certain challenge for finding a new fuel source as a competition for crude oil and allows to get acquisition a new engine fuelling technology.
