摘要： An apparatus and method for recovery of waste heat in a boiler system, wherein heat from the low pressure steam in the feed water tank, which otherwise would be lost through dissipation, is used for other applications. Particularly, the waste heat energy recovered in the form of low pressure steam can be used to heat make-up water for the boiler system.

摘要： A thermal power plant has an exhaust gas system, a feed-water system, a high-pressure feed-water heater provided to the feed-water system, a main economizer, a catalytic NOx removal equipment, and a sub economizer. The main economizer is provided to the secondary side of the high-pressure feed-water heater of the feed-water system and increases the temperature of the feed-water by using the residual heat of the combustion gas from the boiler. The catalytic NOx removal equipment is provided to the secondary side of the main economizer of the exhaust gas system. The exhaust gas is supplied to the catalytic NOx removal equipment at a required temperature or higher. The sub economizer is provided between the high-pressure feed-water heater and the main economizer and increases the temperature of water by using the exhaust gas on the secondary side of the NOx removal equipment.

摘要： A system for supplying feed water for an evaporator in a water-steam circuit has a condenser for condensing steam to obtain water that can be supplied with steam from a turbine installation. A degasification device for degasing condensate is coupled to the condenser such that a first portion of the condensate of the condenser can be fed to the degasification device. The heat exchanger is coupled to the condenser such that a second portion of the condensate of the condenser can be fed to the heat exchanger, the heat exchanger being coupled to a supply line such that feed water can be fed to the heat exchanger. The heat exchanger is configured such that the feed water can be heated using the second portion of the condensate. The heat exchanger is coupled to the degasification device such that the heated feed water can be fed to the degasification device.

摘要： A steam generator feed water heater comprises a pressurized enclosure inside which is a heat exchanger through which the feed water is caused to flow. There is at least one horizontal condensate inlet tube, as well as at least one condensate outlet tube at a low point on the enclosure. A double screen device associated with the condensate inlet tube comprises an inner screen with a cylindrical side wall and, surrounding this inner screen, an outer screen having one end linked to the inner screen. A bottom wall common to both screens constitutes an impact wall facing the inner screen. Passage areas are provided by perforations in the screens not facing each other over most of the perimeter of their transverse cross-sections.
