Abstract (en)
[origin: WO2018024340A1] The invention relates to a method for operating a waste heat steam generator, in particular one designed according to the forced flow principle, comprising an evaporator (16), through which a flow medium flows; an economizer having a number of economizer heating surfaces (10, 14), and having a bypass line (4), which on the flow medium side is connected in parallel to a number of economizer heating surfaces (10, 14). In the method, a variable (30) that is characteristic of the heat energy supplied to the waste heat steam generator (1) for controlling or regulating the flow rate of the bypass line (4) is used, wherein the regulating or controlling of the flow rate of the flow medium through the bypass line (4) takes place at the inlet of the evaporator (16) subject to a supercooling target value (26). The regulating or controlling of the flow rate of the flow medium through the bypass line (4) also takes place at the outlet of the evaporator (16) subject to an overheating target value (110).
