Solar Thermal collectors

Solar Steam Generators

Steam is the most common heat carrier in industry. The Industrial Solar Fresnel Collector is optimized for solar steam generation and is thus the cleanest option for your process heat supply.

 

Alternatively we also offer steam generation solutions based on the waste heat of combined heat and power plants.


How Does A Solar Steam Generator Work?

How Do Solar Thermal Collectors Work?
A typical steam generator using the Fresnel Collectors is represented in the diagram.

Water is pumped through the collector field and partly evaporates due to the concentrated solar irradiation. In a continuous process, the fluid enters the steam drum where steam accumulates at the top and water at the bottom. The steam drum is an insulated vessel that receives the steam produced by the Fresnel collectors and the residual water not evaporated. The accumulated steam at the top of the vessel is discharged by a control valve to the customer’s steam network. The hot water at the bottom is continuously recirculated to the collector field. This reservoir runs at a higher pressure and temperature providing up to 1 hour of storage,  compensating for fluctuations in the demand or eventual shading in the collector field. When steam is released to the factory, feed water is pumped into the steam drum to keep the mass balance. The system is designed with sensors for monitoring the temperature, pressure and irradiation, which permit a safe and automatic operation throughout the day.
