Abstract

The computational fluid dynamics (CFD) assessment was carried out for the combustion of pure Indian coal and the blends of Indian/imported coals at various proportions in a typical 210 M We Indian boiler. The input fuel mass flow rate was calculated in various cases to give the same thermal input to the boiler. The various sub models used for the CFD assessment has been described in the paper. The velocity and temperature profiles of the gas phase, combustion profile of the particles, heat flux distribution to the walls of the boiler and also the thermal efficiency of the boiler were assessed in the present work. It was found that the particle and fluid dynamics play a major role in the heat flux distribution in the boiler. The Indian and imported coal blend proportion of 80/20 showed good thermal efficiency compared to the pure Indian coal and other blend proportions.
