    摘要: As one of the coal reforming treatment steps constituting a coal reforming process, an oxidation treatment step is carried out on a circular grate. For this purpose, there is used a coal reforming apparatus comprising a circular grate, the circular grate being separated into a plurality of zones which include fixed bed zones and mixing zones for fluidizing the coal properly between adjacent fixed bed zones.

    摘要: A CO2 recovery unit 10A according to a first embodiment has a CO2 absorber that removes CO2 in flue gas by bringing the flue gas containing CO2 into contact with a CO2 absorbent 12, and a regenerator 15 that diffuses CO2 in a rich solution 14 having absorbed CO2 in the CO2 absorber. The CO2 recovery unit 10A includes a first compressor 29-1 to a fourth compressor 29-4 that compress CO2 gas 16 discharged from the regenerator 15, a dehydrating column 33 that reduces moisture in the CO2 gas 16 by bringing the CO2 gas 16 into contact with a dehydrating agent 32, a combustion removal unit 41 that removes the dehydrating agent 32 mixed in the CO2 gas 16 in the dehydrating column 33, and a heat exchanger 42 that performs heat exchange between the CO2 gas 16 discharged from the third compressor 29-3 and the CO2 gas 16 discharged from the dehydrating column 33.
