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 8):
The energy saving boiler system of steam supply according to  claim 1 , wherein further comprises an air preheater that is provided downstream the heat exchanger along the flow direction of flue gas in the flue gas channel, the air preheater is comprised of a cold air inlet, a hot air outlet, a middle temperature flue gas inlet and a low temperature flue gas outlet, the flue gas from the middle temperature flue gas outlet of the heat exchanger enters the air preheater through the middle temperature flue gas inlet and preheats the cold air from the cold air inlet, then is exhausted to the chimney through the low temperature flue gas outlet, and the preheated air is delivered from the hot air outlet to the combustor by means of piping so as to support combustion.
