Solar Steam Generators
- Some industries use intensive fuel consuming diesel boilers to supply steam for their industrial processes.
- These boilers can be combined with solar parabolic troughs or Fresnel mirrors (solar concentrators that direct the sun's heat to create steam).
- The collectors heat the thermal oil to very high temperatures
- In turn, the thermal oil heats the water to steam through a heat exchanger.
- Using solar energy, the boiler can be kept as backup and rarely used.
