Work Step by Step

Differing heating needs can be flexibly met by varying the fraction of the steam extracted, denoted by y. For fixed turbine inlet conditions and mass flow rate, an increase in the fraction y to meet a greater district heating need is met by a reduction in power generated. When there is no demand for district heating, the full amount of steam generated in the boiler expands through the turbine, producing greatest power under the specified conditions.
