Title:
CONTINUOUS STEAM GENERATOR
Document Type and Number:
WIPO Patent Application WO2006087272
Kind Code:
A3
Abstract:
The invention relates to a continuous steam generator (1) comprising a surrounding wall (2), which forms a gas draught (20) and whose lower section is configured from gas-tight evaporator tubes (6) that are welded together and whose upper section is configured from gas-tight superheater tubes (6') that are welded together. According to the invention, the superheater tubes (6') are connected downstream of the evaporator tubes (6) on the flow medium side by means of a water separator system (14). The aim of the invention is to provide said system with a 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 (14) comprises a large number of water separator elements (30), each of which is connected downstream or upstream of less than ten evaporator tubes (6), preferably one tube and/or less than ten superheater tubes (6'), preferably one tube on the flow medium side.
