Coal fly ash, a by-product of coal combustion in thermal power plants, is one of the most complex and abundant of anthropogenic materials. For several years, fly ash has predominantly been used as a substitute for material in the construction industry, especially either as a raw material or as an additive in the cement industry all over the world. The wide implementation of low-NO_x combustion technologies in pulverized coal combustion can lead to changes in fly ash properties, which may negatively affect its applicability to the production of building materials. In the study, brief characterization of current deNO_x techniques, applied in power plants for efficient NO_x reduction, is presented and possible alterations in fly ash utilization in concrete production are discussed.

PL

Popiół lotny z węgla, uboczny produkt spalania węgla w elektrowniach cieplnych, jest jednym z najbardziej złożonych i obfitych materiałów antropogenicznych. Od kilku lat popiół lotny jest stosowany głównie jako substytut materiału w przemyśle budowlanym, zwłaszcza jako surowiec lub domieszka w przemyśle cementowym na całym świecie. Powszechne wdrożenie technologii spalania pyłu węglowego przy niskiej emisji NO_x może prowadzić do zmian właściwości popiołów lotnych, co może zaszkodzić ich przydatności do produkcji materiałów budowlanych. W pracy tej przedstawiono krótką charakterystykę współczesnych technik stosowanych w elektrowniach do skutecznej redukcji NO_x oraz omówiono możliwe zmiany w wykorzystaniu lotnego popiołu w produkcji betonu.
