- Company Profile
Mainly applied to trough concentrating solar power generation. The trough mirrors directly reflect the sunlight to the solar collector tube which is located at the focuses of mirrors. The internal heat transfer working medium produce high-temperature and high-pressure steam through heat exchange to drive the turbines to generate electricity. The double circuit system technology which adopts synthetic oil, fused salt, etc as working medium is very mature.
