Kaji Eksperimental Kehilangan Panas pada Dinding Ruang Bakar Fluidisasi Berbahan Bakar Biomassa
Abstract: Biomass has several
advantages, especially as it is renewable in nature. The low energy content
owned by biomass requires the use of effective techniques, such as
gasification. This research was to
determine the rate of heat transfer that occurs in the burning of fuel in the
combustion chamber fluidized types. The benefit of this research is to identify
the heat loss in biomass combustion system. The fuels used in this study are
wood-planed chips, branches of dry wood and areca nut husk. The size of fuel
was 2 to 3 mm. The fuel was weighed to 2 kgs for one testing/biomass. The combustion
duration was 50 seconds. The heat loss in biomass combustors with wood-planed
chips occurred in 30 seconds at Tf 724oC and TW 203 oC, the heat loss was
26813.33 W/m. The heat loss in the combustion chamber with biomass wood-planed
chips in 15 seconds at Tf-average 334 oC and Tw 44 oC, the heat loss was
2947.03 W/m. The heat loss in biomass combustors with branches of dry wood in
30 seconds at Tf 713 oC and Tw 201 oC, the heat loss was 26350.15 W/m. The heat
loss in the combustion chamber with branches of dry wood biomass in 20 seconds
at Tf-average 286 oC and Tw 42 oC, the heat loss was 2479.57 W/m. The heat loss
in biomass combustors with areca nut husk occurred in 20 seconds at Tf 515 oC
and Tw 137 oC, the heat loss was 19453.82 W/m. The heat loss in the combustion
chamber with areca nut husk biomass occurred in 15 seconds at Tf- average 118
oC and Tw 39 oC, the heat loss was 802.81 W/m.
