Výzkum ve spalování biomasy a odpadů v atmosferickém fluidním loži

Research into Biomass and Waste Gasification in Atmospheric Fluidized Bed

Considerable attention is paid in the Czech Republic to renewable energy sources. The largest potential, out of them all, have biomass and waste. The aim therefore is to use them in CHP in smaller units (up to 5MWel). These are the subject of the research summarized in our article. The paper presents results of experimental research into gasification in a 100 kW AFB gasifier situated in Energy Institute, Faculty of Mechanical Engineering, Brno University of Technology, and fitted with gas cleaning equipment. Within the research, study was carried out into gas cleaning taking primary measures in the fluidized bed and using hot filter, metal-based catalytic filter, and wet scrubber. Descriptions and diagrams are given of the gasifier and new ways of cleaning. Results include: o Impact of various fuels (farming and forest wastes and fast-growing woods and culm plants) on fuel gas quality. Individual kinds of biomass have very different thermal and physical properties; o Efficiency of a variety of cleaning methods on content of dust and tars and comparison of these methods; o Impact of gasifier process parameters on resultant gas quality.

V České republice je značná pozornost věnovaná obnovitelným zdrojům energií, z nichž největším potenciálem jsou biomasa a odpady. Cílem je jejich využití v menších jednotkách (do 5MW), jejichž výzkum, je shrnut v následujícím článku. Prezentace představuje výsledky experimentálního výzkumu při zplyňování ve 100 kW zařízení Energetického ústavu fakulty Strojního inženýrství v Brně, vybaveného zařízením pro čištění energoplynu. Během výzkumu byly provedeny studie čištění energoplynu přímo ve fluidním loži a při použití horkého katalitického filtru a mokrého odsiřování. Výsledná kvalita energoplynu je závislá na druhu paliva, jelikož jednotlivé druhy biomasy maí různé fyzikální a energetické vlastnosti.
