    摘要: A method for operating a once-through steam generator including an evaporator, in which a feeding mass flow of a flow medium is supplied using a feed pump to the evaporator and at least partially evaporated there, wherein flow medium that has not evaporated is separated in a separator arranged downstream of the evaporator and a circulating mass flow of the separated flow medium is returned using a circulating pump to the evaporator, and the mass flow referred to as the evaporator mass flow of the flow medium flowing through the evaporator is additively composed of the feeding mass flow and the circulating mass flow. In a low-load interval, the feeding mass flow is increased with increasing load while the circulating mass flow is kept substantially constant, in a moderate load interval the feeding mass flow is further increased with increasing load and the circulating mass flow is reduced to zero.

    摘要: A method for operating a steam generator comprising a combustion chamber having a plurality of evaporator heating surfaces which are connected in parallel on the flow medium side is provided. An object is to provide a steam generator which has a particularly long service life and which is particularly reliable. For this purpose, a flow medium is introduced into an inlet of a first evaporator heating surface at a temperature which is lower than the temperature of the flow medium introduced into the inlet of a second evaporator heating surface.

    摘要: A continuous steam generator is provided. The continuous steam generator includes a number of burners for fossil fuels, the outside wall thereof being fully or partially formed from steam generator tubes welded together in a gas-tight manner. The burners are arranged in a combustion chamber, and a vertical gas duct is mounted downstream of the combustion chamber above a horizontal gas duct on the hot gas side. A first part of the steam generating tubes forms a system of evaporation tubes mounted upstream of a water separator system, on the flow medium side, and a second side, and a second part of the steam generating tubes forms a system of superheater tubes mounted downstream of the water separator system on the flow medium side. Superheater tubes adjacent and parallel to evaporation tubes are mounted directly downstream of the water separator system on the flow medium side.

    摘要: The invention relates to a continuous steam generator comprising a surrounding wall which forms a gas draught and whose lower section is configured from gas-tight evaporator tubes that are welded together and whose upper section is configured from gas-tight superheater tubes that are welded together. According to the invention, superheater tubes are connected downstream of the evaporator tubes on the flow medium side by means of a water separator system. The aim of the invention is to provide a system with particularly high degree of operational flexibility even in the start-up and off-peak periods, whilst keeping the production and installation expenditure relatively low. To achieve this, the water separator system comprises a large number of water separator elements, each of which is connected downstream or upstream of less than ten evaporator tubes, preferably one tube and/or less than ten superheater tubes, preferably one tube on the flow medium side.

    摘要: A method for operating a recirculating waste heat steam generator is provided, in which in a pressure stage of the recirculating waste heat steam generator, the feed water mass flow is guided on the basis of a specified desired value in order to control the water level in a drum. The method should give a recirculating waste heat steam generator a particularly high degree of efficiency and simultaneously a particularly high level of operational flexibility. For this purpose the thermal input introduced into an evaporator of the pressure stage is used as input variable in the determination of the desired value.
