    摘要: 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.

    摘要: An incineration plant includes a heat exchanger arranged in a flue gas flow following a reduction stage for nitrogen oxides and in front of a flue gas dust collector, and a heat transfer medium circuit for absorbing heat from the heat exchanger in the flue gas flow. The heat exchanger is connected to the heat transfer medium circuit such that the heat transfer medium conducted in the circuit is admitted to the heat exchanger. The heat transfer medium circuit has at least one additional heat exchanger for absorbing heat from the heat transfer medium. A feed water preheater is arranged in the heat transfer medium circuit.
