IPL is converting their 3 largest operating units at Harding Street station operate using natural gas fuel. The gas conversion will incorporate a burner management system controls upgrade for all three units and installation of new burners within the three existing boilers as well as igniters. The controls upgrade is a critical phase of the project that will include modification of the system to meet new operating performance requirements for gas-fired generation. The project also includes installation of flue gas recirculating fans, flue gas draft modifications, a control system evergreen update and installation of an auxiliary boiler. Bowen Engineering teamed with engineering partner Burns & McDonnell in an integrated joint venture to complete the work, including design and construction of the project. Following the fuel conversion, generating capacity at the three units will total over 650 megawatts (MW). The conversion project is part of IPL’s compliance plan for its coal-fired units.
