Abstract
Provided are regenerative rotary preheater having flue gas flow passage through which passed is flue gas from oxyfuel combustion boiler, primary-combustion-support-fluid flow passage adjacent to the flue gas flow passage and through which passed is primary combustion support fluid with pressure higher than that of the flue gas, secondary-combustion-support-fluid flow passage adjacent to the flue gas flow passage and through which passed is secondary combustion support fluid with pressure higher than that of the flue gas and oxygen flow passage between the primary- and secondary-combustion-support-fluid flow passages and through which oxygen is passed, and an oxygen mixing section mixing the fluid preheated through the secondary-combustion-support passage with oxygen preheated through the oxygen flow passage and supplies the mixture to the oxyfuel combustion boiler.
