| Abstract: |
| Under the background of the “double carbon” target, combined with the current situation of domestic energy, the coalbed methane injection is used to replace part of the solid fuel for sintering production, and the development of a suitable injection equipment can not only improve the quality of sinter, but also effectively realize the emission reduction and cost reduction of sintering production. In this paper, according to the H2-rich sintering technology principle and combined with the field situation, the parameters of injection equipment were determined, and the industrial test was carried out. The influence of coalbed methane injection on sintering production, quality and energy consumption was analyzed. The research shows that when the injection rate of 0.48 m3/t, the yield changes little, the particle size and strength are obviously improved, the solid fuel consumption is reduced by 2.44 kg/t, the CO2 emission reduction can reach 6.04 kg/t, and the production cost can be reduced by 2.34 yuan/t. |
