Experimental investigation and modelling study of long stick wood gasification in a top lit updraft fixed bed gasifier

Characterization of Biochar from Rice Hulls and Wood Chips Produced in a Top-Lit Updraft Biomass Gasifier

“…7c and 7d). The combustion zone in top-lit updraft gasifiers is partially fueled by the volatiles released from the biomass below this zone in a process often known as flaming pyrolysis (Saravanakumar et al, 2007;Hangfu et al, 2014). This devolatilization phenomenon can be observed by comparing the initial volatiles in the biomass with those in the biochar; rice hulls initially contained 58% volatiles, and wood chips contained 74%.…”

The Effect of Biomass Physical Properties on Top-Lit Updraft Gasification of Woodchips

“…There are a wide number of biomass gasification technologies that are designed to process different feedstock; fixed bed and fluidized bed gasifiers are the two major categories [16]. Examples of fixed bed gasifiers are the downdraft, updraft, crossdraft and top-lit updraft gasifiers [17,18]. Extensive work has been published on the individual production of biochar or syngas [19,20].…”

Carbonization Behaviour of Woody Biomass and Resulting Metallurgical Coke Properties

“…However, the many are the researches on the gasification, [3][4][5][6][7][8][9] and the research that pays attention to carbonization is little. [10][11][12] Ohta et al 11,12) revealed that, when more than 1 % waste wood is screened to below 3 mm, coke strength is lowered and the lowering of coke strength is inhibited by increasing the size of the waste wood to be added.…”
