Charakterystyka paliw alternatywnych dla współspalania w kotłach pyłowych
Języki publikacji
Abstrakty
Natural gas, oil and coal have been the primary source of energy for industries and these are regarded as primary fuels. Although the share of fossil fuels in the European power industry is dominating utilization of alternative fuels for power generation has recently gained a considerable importance. To assure the proper operation of combustion processes in that case fuels properties should be closely monitored. The basic standard and non-standard methods were described underlying the importance of fuel data base for mathematical modelling.
Gaz ziemny, ropa naftowa i węgiel stanowią bazę surowców podstawowych dla wytwarzania energii elektrycznej w Europie. Mimo, że ich udział w wytwarzaniu energii jest dominujący, to coraz większego znaczenia nabiera spalanie paliw alternatywnych. W celu zabezpieczenia właściwych parametrów spalania tych paliw konieczne jest monitorowanie ich właściwości. W pracy opisano podstawowe standardowe i niestandardowe metody badawcze oraz podkreślono ważność znajomości tych parametrów dla potrzeb modelowania matematycznego.
