Steam supply apparatus

Abstract

In this steam supply apparatus, a steam inlet ( 20 a ) of a steam injector ( 20 ) is connected to a steam outlet ( 19 a ) of a high-pressure steam-generating boiler ( 19 ). A solar heat-collector ( 22 ) is connected to an inlet port ( 20 b ) of the steam injector ( 20 ), and steam-utilizing equipment ( 25 ) is connected to a discharging port ( 20 c ). The steam injector ( 20 ) is driven by high-pressure and high-temperature steam ( 27 ) generated by the high-pressure steam-generating boiler ( 19 ), and pressure of the inlet port ( 20 b ) is decreased. In the inner portion of the solar heat-collector ( 22 ) which is decompressed according to a decrease in pressure of the inlet port ( 20 b ), water with a temperature increased by irradiation of the sunlight ( 24 ) is boiled and evaporated at less than 100° C., and low-pressure and low-temperature steam ( 28 ) is generated. The steam ( 28 ) is introduced to the steam injector ( 20 ), mixed with the high-pressure and high-temperature steam ( 27 ) generated by the high-pressure steam-generating boiler ( 19 ), and intermediate pressure and intermediate temperature steam ( 27 a ) is generated. The amount of generated steam in the high-pressure steam-generating boiler ( 19 ) is decreased by supplying the steam ( 27 a ) to the steam-utilizing equipment ( 25 ).
