In the high-scoring, prestigious journal FUEL (IF 8.035, 140 MEiN points) an article entitled Pilot testing and numerical simulations of the multifuel burner for the cement kiln was published, which included pilot-scale experiments and numerical simulations in the rotary cement kiln and addresses combustion related issues.
This study presents the results of the pilot-scale tests (conducted in the 1[nbsp]MW combustion facility at the Institute of Power Engineering), CFD simulations of both pilot-scale and full-scale burner for the cement rotary kiln. On the basis of the experimental data, a numerical investigations of the 1[nbsp]MW pilot facility was made and validated. The numerical modelling, in a pilot-scale burner, was also intended to check the possibility to co-fire petcoke (as a base fuel) with alternative fuels such as MSW, biomass and hydrogen. Finally, the combustion in the industrial scale 75[nbsp]MW cement rotary kiln burner was numerically analysed to analyse the conditions inside the reference cement installation and to propose a possible solutions to allow substitution of fossil fuels with RDF.
The results showed that it is possible to co-fire a high shares of the alternative fuels in the rotary kiln without the negative effects on the combustion performance. It was also found, that the base fuel (petcoke) can be almost completely replaced with the alternative fuels such as RDF or biomass, while addition of the hydrogen to the fuel mixture can even improve the combustion characteristics.
