A method for generating process steam using condensate recycled in the form of feed water is described and illustrated. In order to be able to achieve a higher efficiency with the method, it is proposed that the process steam is delivered to a consumer device (V) to form a condensate by at least partial condensation of the process steam, that the condensate from the consumer device (V) is fed to a feed water treatment for treatment, that feed water from the feed water treatment is separated into a steam phase and a liquid phase in a flash tank, that the liquid phase of the feed water is evaporated in an evaporator to form a raw steam, and that the steam phase of the feed water and the raw steam are compressed in at least one compressor to form process steam.

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.

A heat recovery steam generator (HRSG) includes a base and a top platform assembly disposed on the base. The top platform assembly includes a first top platform auxiliary module having a first rectangular frame in which a steam manifold is disposed, a second top platform auxiliary module having a second rectangular frame in which a high pressure (HP) drum is disposed, and a third top platform auxiliary module having a third rectangular frame in which a low pressure (LP) drum and an intermediate pressure (IP) drum are disposed. Each top platform auxiliary module may be pre-assembled on the ground prior to be raised to elevation for installed on the base.
