... in the system starts to rise with continuous heating in the solar field. When the pressure in the steam drum ( p sd ) reaches a value higher than the load pressure ( p load ), steam is delivered to the consumer (load) network. The Fresnel collector field is arranged in two parallel strings connected...

... 19 04 2021 direct steam generation process heat Fresnel collectors solar energy Direct steam solar systems are characterized by unique properties due to the two-phase flow present in the solar field. The presence of a gas–liquid mixture results in a dynamic system much more...

.... As an important result, a great potential for reducing the fuel consumption and CO 2 emissions of hybrid concept was identified. However, the high investment of Fresnel collectors coupled with low natural gas prices showed the proposed hybrid concept as economically unfeasible. Nevertheless, it is expected...
