Turbine modifications for district heating

This paper discusses the technical and economic feasibilities of retrofitting existing turbine-generators and replacing existing turbine-generators with specially designed district heating units. Topics considered include turbine retrofit options (approach and design criteria, district heating equipment), new district heating turbines (approach and design criteria, turbine selection), and heat generation costs. The conclusions of the analysis include: no technical barrier was discovered for converting the Potomac River Power Plant to a cogeneration facility, additional equipment required for the district heating operation is of conventional design, the existing steam turbines and associated system components can be retrofitted for district heating operation, the modified units retain the flexibility of producing 100% electric power output when the district heating load is disconnected, the district heating system uses indirect heating of water by extraction steam (the purity of which is not degraded), about three and a half times more heat can be extracted from units designed specifically for cogeneration than from modified units, and the described methodology can be used for the assessment of retrofitting existing units to cogeneration operation for power plants located close to heat load centers.
