<P>PROBLEM TO BE SOLVED: To provide an oxygen combustion boiler improved in efficiency by recovering and utilizing heat of the air in a building and an exhaust gas discharged from the boiler. <P>SOLUTION: This oxygen combustion boiler is configured by disposing an air duct for exhausting, including a turbine inside thereof, at an upper section of the building, disposing an opening/closing member at an air inlet of the air duct for exhausting, further disposing a temperature detector for detecting a temperature of the air in the building, and disposing a control device performing an operation for switching the boiler from air combustion to oxygen combustion. The control device allows the air in the building to be exhausted to the air duct for exhausting on the basis of the air temperature detected by the temperature detector, and the power generation turbine disposed in the air duct for exhausting, is allowed to generate power by the exhaust of the air, thus the exhaust heat in the building can be effectively utilized. <P>COPYRIGHT: (C)2012,JPO&INPIT |
