The authors propose a concept of HTAC technology application to the power boilers fired with pulverized coal. So far, HTAC technology was implemented mainly in industrial furnaces fired with gaseous fuels or light oils. In order to investigate the HTAC boiler, several series of numerical simulations have been performed using FLUENT code. A specially emphasis was placed on the main technical and ecological issues that must be considered wherever HTAC technology would be applied in real power station boilers fired with pulverized coal. Mathematical model validation has been done against the experiment performed at IFRF. As an effect of several numerical investigations a final design of the HTAC boiler has been found and the results are presented and discussed in this paper. The proposed HTAC boiler features following major advantages: small size, low harmful substances emission, mainly NOx, high and uniform heat fluxes and very simple construction of the burners. Overall, the present study confirmed that HTAC technology could be a practicable, efficient and clean technology for fossil fuel fired boilers. However, it has to be pointed out that the investigated boiler is only still a concept and before any industrial application much researches have to be done.
