The role of hydrogen in the kinetic mechanism of formation of a carbon fraction of dispersed particles in the combustion of hydrocarbon fuels

The issues of the scientific search for ways to limit emissions of dispersed particles are of particular importance within the context of socially important problem of environmental protection in the field of heat power during the operation of power plants for various purposes. The bulk of the dispersed particles are particles of the carbon fraction. These particles formed during the combustion of hydrocarbon fuel are among the most harmful substances. The high potential hazard of the particles of the carbon fraction is due to the fact that they contain a number of highly toxic mutagens and carcinogens. Moreover, the ultra-small particle sizes allow them to actively penetrate the human respiratory organs. An alternative version of the method for reducing carbon particles emission based on the use of an additive of a small fraction of free hydrogen to the working fluid of a power plant is considered. A number of scientific provisions on the role of hydrogen as a chemical reagent in the acts of formation and burning of carbon particles are substantiated, the validity of which is confirmed by the results of experimental testing. © 2021 Institute of Physics Publishing.
