Selection of a noncondensing, single automatic extraction turbo-generator for the Virginia Polytechnic Institute heating and power plant
The results, based on steam demand during the 1961-1962 to 1980-1981 heating seasons, indicate the following returns on each investment for the various turbo-generators operating with steam inlet conditions of 600 psig, 825°F, extraction at 100 psig, and exhaust at 10 psis: 13.5 per cent for the 25...

| Summary: | The results, based on steam demand during the 1961-1962 to 1980-1981 heating seasons, indicate the following returns on each investment for the various turbo-generators operating with steam inlet conditions of 600 psig, 825°F, extraction at 100 psig, and exhaust at 10 psis: 13.5 per cent for the 2500 KW unit, 15.1 per cent for the 3000 KW unit, 14.6 per cent for the 4000 KW unit, and 12.9 per cent for the 5000 KW unit.
Total investments for the turbo-generators were as follows: $496,860 for the 2500 kw unit, $534,830 for the 3000 KW unit, $615,770 for the 4000 KW unit, and $693,190 for the 5000 KW unit. === Master of Science |
