摘要： The invention relates to a control system for a mill, particularly a roller grinding mill, comprising a mill control device (11), which is designed to control at least one mill characteristic on the basis of an associated target variable, and a fuzzy-control device (13), which is connected to the mill control device (11) and designed to adjust the target variable of the at least one mill characteristic to be controlled when at least one operating parameter of the mill deviates from a predefined normal range as a function of fuzzy rules that are based on said at least one operating parameter of the mill until the at least one operating parameter of the mill has reached the predefined normal range again. A solution is to be provided, which enables automated optimized mill operation even with changing operating conditions, particularly a mill operation that prevents the “mill rumbling”. This is achieved in that the at least one operating parameter of the mill encompasses at least the air pressure difference over the mill.

摘要： For a steam generator comprising a combustion chamber fired with a fossil fuel and/or with particulate fuel containing carbon and at least one burner level comprising several burners (1) and/or at least one level comprising nozzles in the form of upper air nozzles and/or side wall nozzles, each having connected feed means (9, 10, 11, 12) and/or feed lines (2, 4, 5, 9a-9d, 10a-10d, 11a-11d, 12a-12d) through which/by means of which gas flows conveying combustion and/or oxidation oxygen can be fed to burners (1) and/or the nozzles (13) and/or the combustion chamber, a solution should be created by means of which undesired oxygen contents in the flue gas can be avoided during oxyfuel operation of the steam generator in the partial-load range. This is achieved in that the feed means (9, 10, 11, 12) and/or the feed lines (2, 2a-2d, 4, 5, 9a-9d, 10a-10d, 11a-11d, 12a-12d) are designed in such a way that at least one burner (1) or some of the burners (1) independently of the other burners (1) and/or a nozzle (13) or some of the nozzles (13) independently of the other nozzles (13) can be exposed to a gas flow providing the desired oxygen content or the desired oxygen concentration and/or the desired oxygen mass flow.

摘要： In a method for operating and controlling/regulating a power station comprising a coal-fired steam generator (11), the steam generator (11) of which is rated for the steam parameters achievable by the heat transfer onto the steam mass flow upon coal firing in the steam generator (11) carried out using combustion air, a solution is to be created, which enables the operation of coal-fired power stations rated for air operation utilizing a firing of the fuel carried out according to the oxy-fuel process in the firing chamber of the steam generator of the coal-fired power station. This is achieved in that a firing of the fuel containing coal is carried out in the steam generator (11) according to the oxy-fuel process utilizing approximately pure oxygen containing more than 95% by volume, and recirculated flue gas containing a high amount of CO
2 , such that the mass flows of all fuel flows supplied to the coal-fired burners (10) and to the steam generator (11), and the combustion gas, carrier gas, and process gas flows from the combustion oxygen and/or recirculated flue gas are configured and adjusted to each other with respect to the respective composition ratio thereof of oxygen and/or flue gas such that the heat transfer occurring in the steam generator by means of flame radiation, gas radiation, and convection onto the steam mass flow is maintained equal overall in the steam/water cycle as compared to air combustion, in particular, that the same steam parameters are obtained.
