Principles of Free Steam Power Generation
The fundamental principle of free steam power generation involves the conversion of thermal energy into mechanical energy, which is then used to generate electricity. This process is achieved through the use of a steam turbine, which is driven by the expansion of high-pressure steam. The steam is produced by heating water, either directly or indirectly, using waste heat or renewable energy sources such as solar, geothermal, or biomass. As the steam expands through the turbine, it drives a generator, producing electricity.
Types of Free Steam Power Generation
There are several types of free steam power generation systems, each with its own unique characteristics and applications. These include:
- Organic Rankine Cycle (ORC) systems, which use a working fluid with a lower boiling point than water to generate electricity from low-temperature waste heat
- Kalina Cycle systems, which use a mixture of water and ammonia as the working fluid to generate electricity from high-temperature waste heat
- Supercritical Carbon Dioxide (s-CO2) systems, which use CO2 as the working fluid to generate electricity from high-temperature waste heat
| System Type | Working Fluid | Temperature Range |
|---|---|---|
| ORC | Organic fluid | 100-300°C |
| Kalina Cycle | Water-ammonia mixture | 200-500°C |
| s-CO2 | Carbon dioxide | 500-1000°C |
