    • The steam desuperheating valve has a housing (4) with a steam inlet (1), a cooling water inlet (3) and a steam outlet (2). In the housing (4) there are a perforated basket (11) forming a depressurising chamber and an axially movable control piston (5) controlling the flow of steam and cooling water to the depressurising chamber. The control piston (5) is rigidly coupled to a perforated cylinder (6) axially movable in the perforated basket (11). This perforated cylinder (6) releases or blocks the steam inlet (D) into the perforated basket (11) and the steam outlet into a second depressurising chamber (10) arranged around the perforated basket (11). Into the perforated basket (11) projects a coaxial nozzle pipe (14) which is connected outside the perforated basket (11) to the cooling water inlet (3). Inside the perforated basket (11) the nozzle pipe (14) has injection apertures (15) for the cooling water (W). Outside the perforated basket (11) the nozzle pipe (14) projects into the steam outlet (2) and has an injection nozzle (16) at that point for the cooling water (W). A first piston section (7) movable with the control piston (5) in the nozzle pipe (14) alternately opens and closes the injection apertures (15) in the nozzle pipe (14). A second piston section (8) regulates the cooling water inlet (3) in the size of the through-flow cross-section (X) for the flow of cooling water into the injection apertures (15) in the depressurising chamber and/or into the injection nozzle (16) in the steam outlet (2). The second depressurising chamber (10) surrounding the perforated basket (11) is connected via through-flow apertures (17) to the steam outlet (2) forming a third depressurising chamber.

    • The invention relates to a method and apparatus for reducing steam pressure and temperature in a steam conditioning valve, in which steam flow is regulated with the aid of a valve plug (5) displaceably arranged in a valve seating (4), the plug being perforated by a plurality of holes (6), while cooling water is simultaneously taken into the upper portion (8) of the valve and is regulated in proportion to the regulation of process steam, said water being taken through a hollow valve spindle (7) passing through the plug (5) for discharge through a jet (12) downstream of the centre of the departing steam flow. The plug (5) has at least one row of holes (14) in its central region (13). For small opening amounts of the valve (1) process steam is taken through at least one separate duct (15) up to and past the coolant outlet from its openings (16) such as to flow past and break up the coolant, which is ejected from the duct (15) in the vicinity of, and just above the coolant outlet openings (16).

    • The invention relates to a method and a device for operating a steam generator having a water-steam circuit consisting of preheaters (11, 14) heated with bleeder steam, a preheater (3) heated with flue gas, a vaporizer (4), and a superheater (5). According to the method, steam is removed from the flue gas in the evaporator (4), behind or in front of the evaporator (4), in a heat input which deviates from the basic layout of the evaporator and, following a thermodynamic treatment, returned back to the water-steam circuit. A steam conduit (17) branches behind the evaporator (4) in the direction of flow in the water-steam circuit, and a steam deformation valve (21) is arranged therein. Furthermore, steam branch conduits (18) branch off from the steam conduit (17) downstream from the steam deformation valve (21) and lead to the heat exchangers of the water-steam circuit which are heated with bleeder steam.
