  • Mild Combustion is a process defined on the ground of well-identified external parameters, namely the temperature of the reactants and the maximum allowable temperature increase. More specifically it includes processes in which at least the temperature of a single reactant is higher than the stoichiometric ignition temperature of the mixture and the dilution of reactants is such that the maximum temperature increase is lower than the difference between the ignition temperature and the reference room temperature. It was evaluated in some well defined reactor configurations, namely in steady combustion processes evolving in a Well Stirred Reactor [3, 4], in self ignition in quiescent oxidant environment as well as in premixed deflagrative combustion in Opposed Flow Reactor. The last step concerns the study of another important configuration, which is the analogous of the diffusion flame in back-fed combustion, i.e that one in which reactants are separated and inter-diffuse. In the contest of Mild Combustion this is done in a prototypical configuration of opposed jets of hot air versus cold fuel diluent mixture, here referred as Hot Diluted Diffusion Ignition (HDDI) configuration. The peculiarity of these regimes has also been previously hypothesized in relation to both a study for gas turbine and to the relevance as innovative technique for different types of apparata. This ranges primarily for application in gas turbine with low heating value fuels and with special oxidant diluent for high-efficiency thermodynamic cycle relevant for the separation of the carbon-carrier gasses and for their capture-storage. Other significant applications are processes for the destruction of VOC or any kind of low heating value pollutant/fuel with or without enthalpy recovery. (literal)
