Features of Liquid Fuel Burning Processes

Abstract


The general laws of the combustion of liquid fuel were obtained by considering the Gaussian fractional characteristics for the installations of three types: power boilers, experimental installations, and liquid rocket engines. The comparison the thermal resistances of heat transfer from the flue gas to the liquid fuel particle allows determining that the external thermal resistance plays the main role. The paper determines the ignition onset time for a number of types of liquid fuel as a function of external conditions – the temperature of the flue gas, as well as the size and thermal properties of the fuel particle. The use of recurrence relations made it possible to determine the general method of transition from the characteristic of the full Rosen-Rammler residues to the density of the normal distribution of Gaussian fractions. The paper proposes a method of adaptation of the dispersion factor to assess the fractional distribution, and, consequently, the temperature of the flame continuum to the specific requirements of the technology and reliability of ignition of fuel.
