Parabolic trough solar power generation

Parabolic trough technology uses parabolic trough collectors to concentrate solar radiation which heats up the working medium in the vacuum tubes.     High temperature steam is then generated continuously in heat exchange system and thermal storage system and used to drive steam turbine for power      generation. There are four main parts in a parabolic trough power plant: solar field, heat exchange system, thermal storage system and steam turbine       and other power generation devices. On 29th June,2015, HTC officially signed the contract with CGN Solar Energy Development Co. Ltd to supply oil-water        heat exchanger for Delingha 50MW SCP Project.  The contract includes eight equipments of four types: pre-heaters, steam generators, super heaters and        reheaters, all manufactured in line with ASME Standard.
