    摘要: A system (10) for regulating condensation of a flue gas (12) in a steam generator (14) is provided. The system (10) includes a temperature controller (16) and a flue gas analyzer (18). The temperature controller (16) is configured to control a temperature of a component (20, 22, 24) of the steam generator (14), the component (20, 22, 24) being in heating-contact with the flue gas (12). The flue gas analyzer (18) is configured to communicate with the temperature controller (16) and to obtain a measurement of an amount of an acid-forming compound in the flue gas (12). The temperature controller (16) adjusts the temperature of the component (10, 22, 24) based at least in part on the measurement such that the temperature of the component (20, 22, 24) is above an acid dew point of the flue gas (12) when the component (20, 22, 24) is in heating-contact with the flue gas (12).

    摘要: A heat recovery steam generator (10) includes a gas inlet (12) for receiving a flow of exhaust gas (14) from a gas turbine (18), a gas outlet (34) opposite the gas inlet (12), at least one heat exchanger (30) intermediate the gas inlet (12) and the gas outlet (34), the heat exchanger (30) having a plurality of heat transfer surfaces configured to transfer heat from the exhaust gas (14) to a fluid within the heat exchanger (30), and a valve (60) associated with the heat exchanger (30) and configured to regulate a flow of the fluid through the heat exchanger (30). The valve (60) is controllable from an open position to a closed position to decrease the flow of the fluid through the heat exchanger (30) in order to effect an increase in a temperature of the heat transfer surfaces of the heat exchanger (30) to clean the heat transfer surfaces.

    摘要: Method for determining an outlet temperature (T 2 ) of an upstream combustion stage (21) in a gas turbine engine having at least two serially arranged combustion stages (21, 22), a compressor (10) fluidly communicatied with and upstream a most upstream combustion stage (21), and a last expansion turbine (30) fluidly communicated with and downstream a most downstream combustion stage (22). The method comprises obtaining at least one first parameter representative of the inlet temperature (T 3 ) of the most downstream combustion stage (22), obtaining at least one second parameter representative of the outlet temperature (T 1 ) of the compressor (10), and obtaining the fuel massflows (ṁ Fuel,1 , ṁ Fuel,2 ) and/or a fuel massflow ratio between the combustion stages (21,22). An outlet temperature (T 2 ) of an upstream combustion stage (21) is obtained based upon said first and second parameters and the fuel massflows and/or the fuel massflow ratio.
