SOLAR SYSTEM FOR GENERATING STEAM

摘要

PURPOSE:To reduce the installation space and cost for equipment and installations by providing a first heat exchanger in which heat is exchanged between hot thermal medium heated by collected heat and transported feed water as well as a second heat exchanger which generates steam for processing by heating the feed water with the operating medium. CONSTITUTION:Thermal medium 15 heated to the set temperature by collecting heat in a solar collector 1 exchanges heat with feed water 16 in a heat exchanger 2 where the feed water 16 is heated by the thermal medium 15. As the quantity of heat that can be collected by the solar collector 1 exceeds the set value when the sunshine is abundant, only the set amount regulated by a control valve CV3 is introduced into a heat exchanger 12, and the excessive hot feed water 16 passes through a control valve 4 to be stored in a storage tank 3. The feed water 16 now regulated to the set temperature and set flow rate becomes saturated gas by receiving heat of waste heat source 14 in a heat exchanger 9, which is then compressed in a compressor 10 and exchanges heat with operating medium 17 in the heat exchanger 12. Consequently, the feed water 16 becomes usable steam at still higher temperature and pressure and is supplied to the process.
