Computational fluid dynamics modeling of high temperature air combustion in an heat recovery steam generator boiler
Khoshhal A, Rahimi M, Ghahramani A, Alsairafi AA
This paper reports a numerical study on the possibility of using high temperature air combustion (HiTAC) technique in the heat recovery steam generator (HRSG) boiler of the Fajr Petrochemical Complex, Iran. For this purpose a theoretical fuel nozzle which operates in HiTAC mode of combustion has been installed and modeled using the computational fluid dynamics (CFD) technique. By aim of establishing an efficient heat transfer rate to the boiler’s tubes, the proper nozzle location and an optimum mass flow rate of fuel have been found. The results show that by using this modification it is possible to increase the steam temperature up to 37 percent.
Keywords: CFD; HiTAC; HRSG Boiler; Modeling; Heat Transfer
