STIG THERMAL WATER TREATMENT FOR STIG POWER STATION CONCEPTS

摘要

The present invention relates to methods and assemblies for heated water treatment for STIG power station concepts. In the process according to the invention, the heat of the exhaust gas (3) after the heat recovery steam generator stage (4) is used to treat the water in the water treatment system. The heat of the exhaust gas 3 is transferred through the heat element 14 to the water circulating between the condenser 10 and the at least one evaporator 12 in the water treatment system 2 when the gas has a low temperature level do. The treated process water may then be used for steam injection into a gas turbine.
