Facilities for Utilization of Geothermal Steam, Verdant Vales School, Middletown, California

摘要

Verdant Vales School is a boarding school and summer camp located in the Geysers - Calistoga KGRA near Middletown, California. The school consists of dormitories, classrooms and related facilities to accommodate a maximum of 55 students and a staff of 5. Energy for heating buildings and domestic hot water, is provided by electricity supplied by Pacific Gas and Electric Company. In addition, a considerable amount of LPG is consumed to heat the swimming pool and the hot water required for the automatic dishwasher in the kitchen. The school has 3000 pounds per hour of 150 psig steam available at no cost from an existing geothermal well adjacent to the school site. A preliminary design of a system has been developed that utilizes the geothermal steam to eliminate the school's LPG requirement, and minimizes outside purchases of electricity for space and water heating. Savings have been developed, and material costs for the new facilities have been estimated. (ERA citation 06:007637)
