District heating and cooling systems for communities through power plant retrofit and distribution network. Volume 1. Executive summary. Final report. [Downtown Toledo steam system]

Description

The potential service area for a district-heating system includes the existing downtown Toledo steam system and nine new customers. An alternative extends the system about ten city blocks to a large hospital now fueled with oil. The annual peak demands are estimated at 278.6 and 325.8 million Btu/hr., respectively. Retrofit schemes are similar for both service areas. A back-pressure turbine added in parallel with Toledo Edison's Acme Station No. 2 turbine would provide steam at 250 psig. The plant's electrical output would decrease 18 and 23 MW for the two plans. Scarce fuel saved is estimated at 5.2 and 6.0 ... continued below

Description

The potential service area for a district-heating system includes the existing downtown Toledo steam system and nine new customers. An alternative extends the system about ten city blocks to a large hospital now fueled with oil. The annual peak demands are estimated at 278.6 and 325.8 million Btu/hr., respectively. Retrofit schemes are similar for both service areas. A back-pressure turbine added in parallel with Toledo Edison's Acme Station No. 2 turbine would provide steam at 250 psig. The plant's electrical output would decrease 18 and 23 MW for the two plans. Scarce fuel saved is estimated at 5.2 and 6.0 million gallons of No. 6 oil, respectively. Although no insurmountable barriers were apparent, the success of such a system is not guaranteed. Large base-load users must make long-term commitments to support the establishment of a system. Drawbacks to successful implementation include lack of incentive for potential customers to connect to the system due to an apparent abundant supply of natural gas; difficulty in financing due to the higher risk involved; reluctance of utility production services to narrow reserve margins caused by steam extraction; and the future uncertainties about environmental constraints on electric power plants.
