Title:
ENERGY-SAVING GAS SUPPLY BOILER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/075955
Kind Code:
A1
Abstract:
An energy-saving gas supply boiler system, comprising: a steam boiler (100), a flue gas pipeline, a heat exchanger (300), a steam generator (400) and an ejector (500). The steam boiler (100) comprises a boiler body (110), a combusting apparatus (120), a flue gas outlet (130), a water outlet (140) and a high pressure steam outlet (150). The heat exchanger (300) comprises a high temperature flue gas inlet (310), a medium temperature flue gas outlet (320), a cooling water inlet (330) and a hot water outlet (340). Cooling water passes through the cooling water inlet (330), enters the heat exchanger (300), undergoes heat exchange with flue gas and changes into hot water, and flows out from the hot water outlet (340). The steam generator (400) comprises a generator body (410), a hot water inlet (420) and a low pressure steam outlet (430). The hot water inlet (420) communicates through a pipeline with the heat water outlet (340) so as to deliver hot water of the heat exchanger (300) to within the generator body (410). The ejector (500) comprises a housing (510), a high pressure steam inlet (520), a mixing steam outlet (530) and a low pressure steam inlet (540). The high pressure steam inlet (520) communicates with the steam boiler (100) so as to deliver high pressure steam to within the ejector (500). The low pressure steam inlet (540) communicates with the steam generator (400) so as to deliver low pressure steam to within the ejector (500).
