Abstract
Steam turbine cogeneration is a well established technology
which is widely used in industry. However, smaller previously
unfeasible applications can now be cost effective due to the
packaged system approach which has become available in
recent years.
The availability of this equipment in a packaged system form
makes it feasible to replace pressure reducing valves with
turbine generator sets in applications with flows as low as
4000 pounds of steam per hour. These systems produce
electricity for $0.01 to $.02 per kWh (based on current costs
of gas and oil); system cost is between $200 and $800 per kW
of capacity. Simple system paybacks between one and three
years are common.
