Abstract:
An energy-saving gas supply boiler system, comprising: a steam boiler, a flue gas pipeline, a heat exchanger, a steam generator and an ejector. The steam boiler comprises a body, a combusting apparatus, a flue gas outlet, a water outlet and a high pressure steam outlet. The heat exchanger comprises a high temperature flue gas inlet, a medium temperature flue gas outlet, a cooling water inlet and a hot water outlet. Cooling water undergoes heat exchange with flue gas and flows out from the hot water outlet. The steam generator comprises a generator body, a hot water inlet and a low pressure steam outlet. The ejector comprises a high pressure steam inlet, a mixing steam outlet and a low pressure steam inlet. The high pressure steam inlet delivers high pressure steam to the ejector. The low pressure steam inlet delivers low pressure steam to the ejector.

Claim (Index 1):
An energy saving boiler system of steam supply, comprising:\n a steam boiler that is comprised of a boiler body, a combustor that is provided on one end wall of the boiler body, a flue gas outlet that is provided on the other end wall of the boiler body, and a water inlet and a high pressure steam outlet that are provided on the top of the boiler body; and a flue gas channel that connects the flue gas outlet of the boiler body to a chimney; wherein, the energy saving boiler system of steam supply further comprises: a heat exchanger that is provided in the flue gas channel and is comprised of a high temperature flue gas inlet, a middle temperature flue gas outlet, a cold water inlet and a hot water outlet, the cold water enters the heat exchanger through the cold water inlet and changes to hot water that flows out through the hot water outlet after exchanging heat with the flue gas; a steam generator that is comprised of a generator body, a hot water inlet that is provided on the bottom of the generator body and a low pressure steam outlet that is provided on the top of the generator body, the hot water inlet is connected to the hot water outlet of the heat exchanger by means of piping, so as to deliver the hot water in the heat exchanger into the generator body; and an injector that is comprised of a housing, a high pressure steam inlet that is provided on one end wall of the housing, a mixed steam outlet that is provided on the other end wall of the housing, and a low pressure steam inlet that is provided on the side wall of the housing, the high pressure steam inlet is connected to the high pressure steam outlet of the steam boiler by means of piping, so as to deliver the high pressure steam into the injector, and the low pressure steam inlet is connected to the low pressure steam outlet of the steam generator by means of piping, so as to deliver the low pressure steam into the injector.
