| 摘要 |
The invention relates to the use of a low-viscosity sulfur as a cost-effective heat transfer and heat storage fluid, the viscosity thereof being greatly reduced by saturation with hydrogen sulfide. Alternatively, the reduction in viscosity is optionally obtained by adding sulfur chloride. The melting point can be reduced by adding phosphorous. The temperature range of the use is from 130° C. up to 700° C. The fluid is particularly suitable for solar thermal power plants.
