How are noncondensing steam turbines used for cogeneration?

Noncondensing steam turbines are highly efficient tools for cogeneration, a process that utilizes steam for both power generation and heating.1

In this configuration, high-pressure, high-temperature steam from a boiler is passed through the turbine to generate power. Unlike condensing turbines, which expand steam to the lowest possible pressure to maximize work output, noncondensing turbines exhaust steam at or above atmospheric pressure.21

Because this exhaust steam retains significant thermal energy, it is ideally suited for industrial processes or heating applications, such as warming buildings or processing food products. By repurposing this medium-pressure steam rather than discharging it to a condenser, facilities can achieve considerable overall energy savings. This approach is particularly economical for industrial plants where there is already a substantial demand for process steam.21
