Working of Turbine (Expanders)

The expansion of a gas in a nozzle to produce a high-velocity stream is a process that converts internal energy into kinetic energy, which in turn is converted into shaft work when the stream impinges on blades attached to a rotating shaft. Thus a turbine (or expander) consists of alternate sets of nozzles and rotating blades through which vapor or gas flows in a steady-state expansion process. The overall result is the conversion of the internal energy of a high-pressure stream into shaft work. When steam provides the motive force as in most power plants, the device is called a turbine; when it is a high-pressure gas, such as ammonia or ethylene in a chemical plant, the device is usually called an expander.

What is First Law of Thermodynamics?

In a closed system undergoing a thermodynamic cycle, cyclic integral of heat and cyclic integral of work are proportional to each other when expressed in their own units and are equal to each other when expressed in the consistent(same) units.
