Spray characterization in a lean premixed and prevaporized combustion (LPP)

The process of combustion inside power plants is achieved generally by the external mixing between the fuel and air that is by a system that produces a diffusive flame. This type of combustion needs a careful planning of the system injection to optimise the processes that influence the exchanges of momentum between air and fuel. Such combustion is characterized from a "core" of combustion at high temperature accountable for the elevated middle temperature in the whole thermal area. The maximum temperature in this typology of system are generally of the order of 2400°K reducing from the core to the peripheral zone getting spatial middle temperature about 970K. This combustion has, above all for the heavy fuel, the limit to produce polluttants like NOx, SOx, IPA
