    Abstract: The invention concerns a powder drying system (1) comprising a carbon monoxide (CO) gas detection system adapted for detection of CO gas from smoldering powders in a powder drying system component, such as a spray dryer chamber (200), a fluid bed (500) or a bag filter (400), which CO gas detection system comprises at least one inlet CO gas detector (3) arranged on at least one gas inlet of a powder drying system component such as to provide at least one inlet CO gas content measurement, at least one outlet CO gas detector (3) arranged on at least one gas outlet of a powder drying system component such as to provide at least one outlet CO gas content measurement, and an analyzing unit (5) adapted for receiving the at least one inlet CO gas content measurement, receiving the at least one outlet CO gas content measurement and comparing the sum of the at least one inlet CO gas content measurement and the sum of the at least one outlet CO gas content measurement while compensating for dilution, mixing, and time delay of the outlet CO gas content measurement. At least the at least one outlet CO gas detector (3) comprises an IR laser transmitter and is adapted for detecting over a measurement volume (6) and is arranged on the at least one gas outlet in such a way that said measurement volume (6) extends directly inside a gas flow (20) in said at least one gas outlet.

    Abstract: The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75). The rotatable diversion member (75) is configured to be rotated between a first position and a second position to allow that fluid communication is selectively provided between the first opening (72) and the third opening (74) and between the first opening (72) and the second opening (73) of the valve housing (71).

    Abstract: The insert (20) is adapted to be fitted into an atomizer wheel. Each insert (20) has a longitudinal axis and comprises an inner end face (21), an outer end face (22), an external surface (23) and an internal surface (24) defining a channel (35) having a centre axis (c) and extending between an inlet (25) at the inner end face (21) and an outlet (26) at the outer end face (22). At least the inlet (25) is offset from the longitudinal axis such that the centre axis of the channel (35) is offset from the longitudinal axis of the insert (20). The insert (20) is adapted to be utilized in an atomizer wheel for a spray dryer for atomizing slurries of abrasive material, for instance for spray drying absorption for flue gas cleaning.

    Abstract: A method for training an operator of a spray drying plant, the spray drying plant including a plurality of plant elements including pre-processing elements, a spray drying element, post-processing elements, powder recovery elements, and a programmable logic controller, PLC. The method including the steps of: obtaining a transient model of the spray drying plant, wherein the transient model includes transient sub-models of the plurality of plant elements; calculating repeatedly simulated sensor data based on the obtained transient model, using a processing unit; displaying on a display a training human machine interface, tHMI, configured to communicate with the transient model of the spray drying plant, and to display the simulated sensor data and control data for the transient model; and updating the transient model based on operator input on the tHMI, for controlling the transient model of the spray drying plant.
