“…The calcination of clay materials can be accomplished using a number of techniques. In the past, shaft kilns were commonly used [24], whereas now, calcination in a rotary kiln is more often used. The calcination temperature using these technologies is approximately 1000 • C. They are characterized by a long calcination process time (up to several hours), which does not guarantee the complete combustion of the carbon accompanying clay raw materials.…”

“…An alternative method of calcining clay raw materials is calcination in a fluidized bed. So far, fluidized bed furnaces on an industrial scale have only been used for burning limestone in the production of quicklime [24,31]. However, research carried out on a laboratory scale [31][32][33][34][35][36] and the pilot installation [37] demonstrated the potential of this technology to be used in the calcination of clay raw materials.…”

“…Metoda Webba polega na zakwalifikowaniu badanej jednostki terytorialnej do jednego z ośmiu typów rozwoju ludności, w zależności od znaku i wartości bezwzględnej przyrostu naturalnego i salda migracji na pobyt stały w przeliczeniu na 1000 ludności. Metoda ta jest metodą uniwersalną, wykorzystywaną dla różnych jednostek przestrzennych zarówno na poziomie krajowym, jak i międzynarodowym (Biały, Długosz, 2015;Haczek, Kłos, 2019;Majdzińska, 2018;Piech, 2021) 2021a). Dokonaną diagnozę sytuacji demograficznej -w ujęciu regionalnym-pogłębiono odnosząc zdiagnozowany typ sytuacji demograficznej do poziomu rozwoju gospodarczego oraz jego zmian.…”
