Torrefied biomasses in a drop tube furnace to evaluate their utility in blast furnaces
Abstract
Torrefaction and burning characteristics of bamboo, oil palm, rice husk, bagasse, and Madagascar almond were studied and compared with a high-volatile bituminous coal using a drop tube furnace to evaluate the potential of biomass consumed in blast furnaces. Torrefaction at 250 and 300°C for 1h duration was carried out. Analysis using the ash tracer method indicated that the extent of atomic carbon reduction in the biomasses was less than that of atomic hydrogen and oxygen. Torrefaction also lowered the sulfur content in bamboo and oil palm over 33%. An examination of the R-factor and burnout of the samples suggests that more volatiles were released and a higher burnout was achieved with raw and torrefied biomasses at 250°C than at 300°C; however, torrefaction at 300°C is a feasible operating condition to transform biomass into a solid fuel resembling a high-volatile bituminous coal used for blast furnaces.

A typical study on hydrothermal (wet) torrefaction results in 10% reduction in energy yield compared with a dry method under similar operating conditions.
“For instance, a typical study on hydrothermal (wet) torrefaction results 10% reduction in energy yield compared with that of a dry method under the similar operating conditions (Chen et al., 2012).”

Torrefaction decreases the burnout rate of biomass because of the low volatile content in torrefied biomass.
“The burnout rate of biomass decreases after the torrefaction because of the low volatile content in the torrefied biomass (Chen et al., 2012).”

The burnout time of torrefied biomass is shorter than that of coal because of its more porous structure and remaining volatile matter.
“The burn out time is, however, shorter than that of coal (Chen et al., 2012) because of its more porous structure and remaining volatile matter.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
