COMBUSTION BEHAVIOR AND EMISSION OF CARBONIZED BIOMASSLIGNITE BLENDED BRIQUETTES
Abstract: Karakteristik dan
Emisi Pembakaran pada Briket Campuran Biomasa-Lignit. The biomass briquette is
an alternative energy resources for the home industries as well as the power
generations in many countries. In this study, the combustion behavior and
emission characteristic of bio-briquettes from carbonized biomass (e.q.;
Rice-hull and teak wood) and lignite coal blended are comprehensively
investigated. The biomass used in this experiment consists of 50% rice husk and
50% teakwood. Biomass (B) and lignite (C) were mixed together with a
composition of 50% C/B, 70% C/B and 100% C/B respectively. All compositions
were added with 30% binder from cassava. Each composition was selected 3grams,
4 grams and 5 grams to be briquetted inside a cylindrical molding (17mm
diameter) and pressed under 100kg/cm2. The bio-briquettes are dried naturally
at atmospheric temperature for 4 days before examined. The combustion
performance and emission characteristics of each type of briquettes were
investigated in a cylindrical combustion furnace equipped with measurement
devices such as mass balance, thermocouple and exhaust gas analyzer. The
burning rate and furnace temperature of each fuel composition were measured
during the combustion process. An analysis
was performed from the comparison of the data recorded in the form of graphs
and tables. Emissions of the bio-briquettes combustion were examined using
digital smoke analyzer, MEXA Analyzer, during the combustion process. The
results of the study indicate that additional of the biomass carbonized into
bio-briquettes offers the advantageous on combustion rate and emissions
pollution. The rapid increase in the temperature in the combustion chamber was
affected by the reaction rate between a fuel and oxygen as well as the size of
fuel burned. The smaller the briquettes result in the faster the burning
process and leads the higher the temperature in the combustion chamber.
