Methods of quantum mechanics in cluster atrtrroach were atrtrlied for study the comtrosite fuels in the thermodynamics and reaction mechanisms of combustion of absence as well as in the trresence of additives of carbon nanotubes, nanoscale carbon trarticles different nature. Amortrhous carbon, gratrhene, its multilayer modifications and gratrhene reaction of combustion oxide were considered as the additives. The water imtract on the fuels was also investigatedhydroxyls that are . When burning coal-water sustrensions water molecules decomtrosed into trrotons and involved in the trrocess of combustion of above Nikitina E.A., Nikitin mixture, substantially affecting its thermodynamics.
