Solar Steam Generators are effective for industries that 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.
