摘要： To provide a power generation system that recovers heat from low-temperature exhaust gas of not more than 150° C. and utilizes the heat to increase an amount of generated electric power of a steam turbine, whereby efficiency in thermal use can be improved. A power generation system includes heat exchangers and configured to exchange heat of a heat medium and heat of water, and a vacuum flasher configured to supply steam to a vacuum stage of a steam turbine, wherein heat media are supplied to the heat exchangers and so as to generate a water fluid having a temperature exceeding a water boiling point under vacuum of a vacuum stage, the water fluid is supplied to the vacuum flasher to generate steam under vacuum of the vacuum stage, and the steam is introduced into the vacuum stage of the steam turbine, whereby an amount of generated electric power is increased.

摘要： An improved ethylene oxide process whereby residual heat is recovered from the reactor coolant by generating steam. The improvement enables the plant to operate using an improved silver-based catalyst with lower optimum operating temperature than that of the alumina-supported silver catalyst for which the plant was designed. The process comprises the steps of passing the coolant from the reactor to at least one first coolant condenser(s) wherein at least part of the coolant vapor is condensed by exchanging heat with boiler feed water to generate steam. The vapor-liquid two-phase stream coming out of said first coolant condenser(s) is passed through a vapor-liquid separator whereby the liquid coolant is separated from the coolant vapor and flows via a "U" trap to coolant surge drum(s) and the coolant vapor passes through a second condenser(s) adapted for generating steam with a lower pressure than that of the steam generated by said first coolant condenser; wherein said "U" trap has a sufficient height to insure that the coolant vapor flows upward to said second coolant condenser(s).

摘要： 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.

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.
