Research on the rundle circulation and green utilization of the thermal energy from coal gasification
Based on the two stage pressurized gasification technology of dry pulverized coal by Xi”an Thermal Power Research Institute Co.,Ltd and DRI(direct reduced iron) cogeneration technology of high temperature dust removal from iron granular bed,the related industries of power generation,iron and steel,non-ferrous metal,chemistry and building material can be linked to form the industrial park of the rundle circulation and green utilization of the thermal energy from coal gasification.The partial CO2 from the park can be used to produce chemicals,this can not only achieve cleaner production,energy saving and emission reduction,but also can dramatically increase the utilization efficiency of coal resource.The generating efficiency of IGCC is about 15% higher than that of conventional coal-fired power generation.If the residual heat of raw gas is not considered,then the energy consumption of DRI is only 218 kgce/t.Fe,31 1kgce/t.Fe lower than that of key state-owned iron-making enterprises in 2009: 529kgce/t.Fe and is only 41.21% of the energy consumption of blast furnace iron-making,with an energy saving rate of up to 58.79%.
