Abstract

In this study, the boiler of Mashhad Toos power plant is studied numerically in order to investigate the possibility to improve its efficiency and reduce its pollutants emission. In this regard, first the current status of the boiler is simulated and the numerical results are compared with the available experimental data, where a good agreement is observed. Next, the effects of the injected fuel droplets’ diameters, air flow rate and the inlet air swirl direction arrangement on the boiler thermal efficiency and pollution emissions are studied. An appropriate arrangement of the inlet air swirl directions for the nine liquid-fueled burners of the boiler is proposed that will lead to a higher boiler thermal efficiency and lifetime.
