Continuous steam generator

Abstract

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.

1 .- 4 . (canceled) 
     
     
         5 . A continuous steam generator, comprising:
 a plurality of burners for fossil fuel;   a plurality of steam generator tubes;   a combustion chamber;   a vertical gas duct;   a horizontal gas duct; and   a moisture separation system,   wherein a surrounding wall of the plurality of burners is completely or partially formed from steam generator tubes welded together in a gas-tight manner,   wherein the plurality of burners are disposed in the combustion chamber downstream of which the vertical gas duct is mounted above the horizontal gas duct on a hot gas side,   wherein a first part of the plurality of steam generator tubes is implemented as a system of evaporator tubes mounted upstream of a moisture separation system on a flow medium side, and   wherein a second part of the steam generator tubes is implemented as a system of superheater tubes mounted downstream of the moisture separation system on the flow medium side, and   wherein a plurality of superheater tubes in parallel contiguity with the plurality of evaporator tubes are mounted immediately downstream of the moisture separation system on the flow medium side.   
     
     
         6 . The continuous steam generator as claimed in  claim 5 ,
 wherein a combustion chamber wall is formed from the plurality of evaporator tubes and a sidewall of the horizontal gas duct is formed from the plurality of superheater tubes, and   wherein the plurality of superheater tubes adjacent to the combustion chamber is mounted immediately downstream of the moisture separation system on the flow medium side.   
     
     
         7 . The continuous steam generator as claimed in  claim 5 , wherein a top of the once-through steam generator is formed from the plurality of superheater tubes which are mounted immediately downstream of the moisture separation system on the flow medium side. 
     
     
         8 . The continuous steam generator as claimed in  claim 5 , wherein vertically disposed superheater tubes in parallel contiguity with the plurality of evaporator tubes are designed such that the flow medium flows through the plurality of superheater tubes from top to bottom.
