Methods of quantum mechanics in cluster approach were applied for study the composite fuels in the thermodynamics and reaction mechanisms of combustion of absence as well as in the presence of additives of carbon nanotubes, nanoscale carbon particles different nature. Amorphous carbon, graphene, its multilayer modifications and graphene reaction of combustion oxide were considered as the additives. The water impact on the fuels was also investigatedhydroxyls that are . When burning coal-water suspensions water molecules decomposed into protons and involved in the process of combustion of above Nikitina E.A., Nikitin mixture, substantially affecting its thermodynamics.
