The WILPO L 241 Analyser is designed for rapid determination of basic coal quality parameters (ash [Ar<\/sup>], moisture [Wt<\/sub>r<\/sup>] and sulphur [St<\/sub>r<\/sup>] and immediate determination of the calorific value [Qr<\/sup>i<\/sub>] in technical coal samples (in working condition).<\/p>\n The design of the unit and original, patented measurement methods enable the analyser to be used in laboratories in mines, power plants, heat generating plants, coke plants, and also in on-site testing laboratories, storage yards, etc.<\/p>\n Our most recent development among analysers, the WILPO L 241, can measure four basic coal quality parameters with higher accuracy than WILPO L 132 \/ L 142 analysers and eliminate or minimize the impact of chemical composition variability of coal on measurement results.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.wilpo.pl\/wp-content\/uploads\/2023\/07\/analizator-wegla-laboratoryjny-wilpo-1.jpg” title_text=”analizator-wegla-laboratoryjny-wilpo (1)” show_in_lightbox=”on” align=”center” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” header_2_text_color=”#7fda41″ global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#000000″ global_colors_info=”{}”]<\/p>\n The WILPO L 241 Analyser is designed as a single-module unit, which enables its easy use in any place.<\/p>\n The measurement vessel with the coal (or e.g. biomass) sample, upon placing it on the loader, is positioned precisely between probes in the measurement paths. During measurement the vessel is slowly rotated so that the entire sample is shifted many times between the probes. The sample is exposed to gamma rays, X-rays and microwaves and the measurement signals (electric pulses) from respective measurement paths are relayed to the control and measurement module, where they are counted and processed. Results of every measurement, along with additional information entered from the keyboard, such as sample number, coal buyer, etc., appear on the display and are automatically saved in computer memory.<\/p>\n The database that is created enables printing out of results as required by the user, e.g. results from a period of one month for coal sent to a selected buyer or provided by a selected supplier, results for samples analysed during one day with daily mean values of coal quality parameters, etc. The latest probes, electronic large-scale integration components and a fast computer system with printer provide reliable and accurate operation, as well as comfort of use.<\/p>\n .<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.wilpo.pl\/wp-content\/uploads\/2023\/07\/schemat-analizator-wegla.jpg” title_text=”schemat-analizator-wegla” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#000000″ global_colors_info=”{}”]<\/p>\n Fig. 1 shows a simplified diagram of the analyzer, where:<\/strong><\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” header_2_text_color=”#7fda41″ global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” header_2_text_color=”#7fda41″ header_3_text_color=”#7fda41″ custom_margin=”||6px|||” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#000000″ global_colors_info=”{}”]<\/p>\n A ca. 1 kg sample, in as-is condition, is poured into a crusher (preferably a roll crusher, e.g. LAB-08-240), where it is comminuted. Afterwards the coal sample comminuted to grain size 0 to 6 mm is poured, without weighing and drying, to the measurement vessel and the top surface of coal is levelled with the roller, which is part of instrument equipment (the measurement method applied eliminates the effect of sample packing on measurement results). The sample is levelled with the roller in order to ensure complete filling of the vessel and thereby to ensure proper measurement.<\/span><\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.wilpo.pl\/wp-content\/uploads\/2023\/07\/przygotowanie-probki-analizator-min-800×500-1.jpg” title_text=”przygotowanie-probki-analizator-min-800×500″ align=”center” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” header_2_text_color=”#7fda41″ header_3_text_color=”#7fda41″ custom_margin=”||6px|||” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#000000″ global_colors_info=”{}”]Realizacja pomiaru jest r\u00f3wnie\u017c prosta i ogranicza si\u0119 do ustawienia naczynia z pr\u00f3bk\u0105 na podajniku analizatora, wsuni\u0119ciu podajnika do urz\u0105dzenia i wci\u015bni\u0119ciu na klawiaturze przycisku startu pomiaru.
