| Abstract: | In terms of the addition of recycled flue gas from the rear of boiler and separated oxygen from the air separation unit,comparisons were conducted between the calculation methods of enthalpy for conventional air-fuel combustion and those for the oxy-fuel combustion.The variation of recycled flue gas enthalpy,separated oxygen enthalpy and inlet gas enthalpy of the furnace with the oxygen concentration was analyzed in the oxy-fuel combustion boiler.And the calculation methods of flue gas enthalpy for oxy-fuel combustion was proposed,which could provide the theoretical basis for the thermal calculation of oxygen-enriched boiler. |
