摘要： A steam generation system (10) includes one or more liquid reservoirs (12) and a steam generator (14) converting liquid from the liquid reservoirs (12) into steam during a steam cycle. The liquid reservoirs (12) are connected to the steam generator (14) via a first liquid line (16) and via a second liquid line (22). First and second fluid level sensors are associated with a minimum level and with a maximum level of liquid in the steam generator (14), respectively. A fill pump (20) is located along the first liquid line (16) and controls liquid exiting the liquid reservoirs (12) and entering the steam generator (14). A drainage pump (24) is located along the second liquid line (22) and controls liquid exiting the steam generator (14) and entering the liquid reservoirs (12). The steam generator (14) is connected to steam output (28) via a steam line (26). The calibration method comprises the step of estimating a flow rate of a component of the steam generation system (10) which may be the steam generator (14) or the fill pump (20) or the drainage pump (24). The flow rate of the component of the steam generation system (10) may be estimated at the beginning of a steam cycle or during a steam cycle or after a steam cycle.

摘要： The invention relates to a method (200) of controlling a steam generation system (10) which includes one or more liquid reservoirs (12), a steam generator (14) and a steam output (28). During a present steam cycle, an injection time in which a steam generator (14) injects steam is determined. The injection time is multiplied by a predetermined steam flow rate of the steam generator (14). Based on the predetermined steam flow rate and on the injection time, a quantity of liquid remaining in the liquid reservoirs (12) is determined. Based on the predetermined steam flow rate and on the quantity of liquid remaining in the liquid reservoirs (12), a remaining time is determined.

摘要： A method is disclosed for anticipating operation characteristics of a steam generation system, the steam generation system comprising at least one boiler (10). The method comprises conducting a fuel analysis of a solid fuel and anticipating the at least one operation characteristic of the steam generation system at the time when a specific partial quantity of solid fuel is combusted in the furnace of a boiler of the steam generation system, and further determining at least one adapted setpoint of at least one operation parameter of the steam generation system dependent upon the fuel composition of any specific solid fuel partial quantity so as to counteract and/or remedy changes of the at least one operation characteristic which are caused by the fuel composition of the specific solid fuel partial quantity. The method may be employed to improve operation of a steam generating system when the fuel composition varies.

摘要： The invention relates to a method and to a corresponding device for determining at least one model parameter (M) of a control engineering model of a steam generator, wherein a control engineering model structure having the at least one characteristic model parameter is predetermined for the steam generator. Measurement signals of the steam generation process are recorded online. According to the invention, the at least one model parameter is estimated online. For this purpose the same input signal (ES) is applied to both the real process (P) and the model of the steam generator. Next, an estimability analysis (SBA) is carried out, wherein at least one output signal of the respective process (ASP) and/or model (ASM), or at least one input signal, are processed by a comparative evaluation on the basis of a gradient analysis (SWG). Estimation ranges within which a valid parameter estimation is possible are defined in a further step on the basis of the gradient analysis. If the estimability is positively assessed, the current estimated value of the at least one model parameter is improved and furthermore the model is adapted by means of the estimated values in an iterative process. The invention further relates to a control unit for a steam generator and to a computer program product.

摘要： A boiler control system includes a first device (51) for measuring or computing a rate of change in steam temperature and a generated thermal stress in a pressure part of a boiler, and a second device (60) for controlling a steam temperature or a rate of change in the steam temperature at the pressure part of the boiler in accordance with a desired value, and a third device(71) which was functions for storing in a memory (54) combinations of the steam temperature and the thermal stress at each moment as obtained by the first means (51); for determining, from the combinations stored in the memory, a relationship between a steam temperature changing rate and a maximum thermal stress caused by the steam temperature changing rate; determining, in accordance with the relationship, a steam temperature changing rate limit value necessary for maintaining an actual thermal stress in the pressure part of the boiler below a maximum thermal stress limit value which is predetermined beforehand or which is given for each start-up of the boiler; and delivering the steam temperature changing rate limit value or desired steam temperature value obtained by integrating the steam temperature changing rate limit value to the second device as the desired value.
