Abstract Combustion process in flare systems is very important from protection of environmentaspects It is used heavily in chemical industries especially in refinery gas andpetrochemical plants In this process poisonous combustive and corrosive gases areconverted into less hazardous materials The length and amount of flame deviation due tocross flow wind are two major subjects in non premixed flames of flares The shape andlength of flame play an important role in radiative heat transfer to equipments in site aswell as calculation of flare height In order to study different factors such as ratio of crossflow to the flow of discharged fuel jet heating value of the fuel and Wobbe number onshape and length of flame simulation of combustion process in flare at jet velocities of 40m s and various cross flow velocities have been done According to results the flamelength decreases initially by increasing of the ratio of air velocity to jet velocity and then itincreases It also can be understood that flames with higher heating value are longer andfuels with similar Wobbe number results in similar flame shapes In order to prepare acomprehensive model for fast prediction of length and deviation of flame an ArtificialNeural Network A N N model was designed and developed For this purpose all ofrequired data for preparing A N N model were obtained from simulation of combustionprocess in flare at jet velocities of 20 30 40 60 and 80 m s and various cross flowvelocities Another A N N model was designed and developed for identifying thecombustion specification such as heating value stoichiometric mass ratio of oxidant tofuel and enthalpy of combustion product The required data for using in A N N model forvarious fuels is obtained from a pre developed program based on chemical equilibrium Also for easy generation of data for conventional design methods of flare and developedA N N model a software with user friendly graphical interface is designed and created
