摘要： An apparatus of measuring a small scale property of a sheet, the apparatus includes: a first light source for illuminating the sheet moving with respect to the illumination; a detector for forming a total intensity of reflection of the light illuminating the moving sheet by each detection; a detected dimension of the reflection on the sheet in the direction of the movement being limited the same as or shorter than a lowest acceptable spatial resolution of the measurement; a duration of each detection being equal to or shorter than the lowest acceptable spatial resolution divided by a speed of the moving sheet; and a processing unit for forming information about a small scale variation of gloss of the sheet on the basis of the detections by the detector.

摘要： A method for obtaining information on quality of combustion of a liquor in a chemical recovery boiler. The method comprises entering a value of a first input parameter to a computational model configured to determine, based on the value of the first input parameter, a value of the quality of combustion of the liquor in the chemical recovery boiler, and at a first time, running the computational model to obtain a first modelling result. The method comprises measuring, from the chemical recovery boiler a value indicative of carryover to obtain a measurement result; comparing the first modelling result with [a] the measurement result or [b] a result derived from the measurement result, to obtain a primary comparison result; and adjusting the value of the first input parameter based on the primary comparison result to obtain an adjusted value of the first input parameter. The method comprises entering the adjusted value of the first input parameter to the computational model, and at a second time, running the computational model to obtain the information on quality of combustion of the liquor in the chemical recovery boiler.

摘要： A method for controlling carryover in a chemical recovery boiler. The method comprises feeding black or brown liquor to a furnace of the chemical recovery boiler through an injection gun to burn the black or brown liquor. The chemical recovery boiler comprises a bullnose, which narrows the furnace, and a first superheater, of which at least a part is arranged at a higher vertical level than the bullnose. The method comprises measuring information indicative of a spatial temperature distribution on a cross section of the furnace, wherein the cross section is above the injection gun and below the first superheater; determining primary information indicative of carryover using the information indicative of the spatial temperature distribution on the cross section of the furnace; and controlling a temperature of the black or brown liquor that is fed to the furnace using the primary information. In addition, a system for performing the method.

摘要： A monitoring apparatus for a doctoring comprises a vibration sensor which is individual and is attached at a discrete location of a doctor blade arrangement, the at least one vibration sensor converting a mechanical vibration of the doctor blade arrangement to an electrical signal, the mechanical vibration being caused by the doctor blade in response to a scraping operation of a rotating roll which is in contact with a moving web. A data processing unit receives the electrical signal carrying information on the vibration, compares said vibration with a reference of at least one previous measurement of a same grade of the web, and start one or more preventive actions in order to avoid a drop-through in the case said vibration exceeds at least one boundary of the reference.

摘要： Sensor modules are triggered to start and stop the measurement approximately synchronously by sending a broadcast message. Information on the timeline of local clocks is also collected by local counters, and any relative differences in the local clocks, local sample clocks or local time stamps are rectified afterwards by means of the collected timeline information.
