These days, the development of various pre- and post-combustion techniques has been pursued in order to reduce theemission of CO2 in the fleet of coal-fired power plants, since it is of great importance to each country’s energy productionwhile also being the single largest emitter of CO2. As part of this kind of research efforts, in this study, a novel burningmethod is tried by the co-burning of the pulverized coal with the stoichiometric mixture of the hydrogen and oxygen(H2+1/2O2) called as HHO. For the investigation of this idea, the commercial computational code (STAR-CCM+) wasused to perform a series of calculation for the IFRF (International Flame Research Foundation) coal-fired boiler (Micheland Payne, 1980). In order to verify the code performance, first of all, the experimental data of IFRF has been successfullycompared with the calculation data. Further, the calculated data employed with pure coal are compared with the co-burningcase for the evaluation of the substituted HHO performance. The reduced amount of coal feeding was fixed to be 30%and the added amount of HHO to produce a similar flame temperature with pure coal combustion was considered as 100%case of HHO addition. This value varies from 100 to 90, 80, 60, 50, 0% in order to see the effect of HHO amount onthe performance of pulverized coal-fired combustion with the 30% reduced coal feeding. One of the most important thingfound in this study is that the 100% addition of HHO amount shows approximately the same flame shape and temperaturewith the case of 100% coal combustion, even if the magnitude of the flow velocity differs significantly due to the reducedamount of air oxidizer. This suggests the high possibility of the replacement of the coal fuel with HHO in order to reducethe CO2 emission in pulverized coal-fired power plant. However, an extensive parametric study will be needed in nearfuture, in terms of the reduction amount of coal and HHO addition in order to evaluate the possibility of the HHOreplacement for coal in pulverized coal-fired combustion.
