“…According to the report, the cold gas efficiency was in a comparable range of 72%-76% for oil palm frond wastes and 66%-70% for tung tree wastes [15]. Further, it was also comparable to the downdraft gasifier efficiency of 62% using charcoal in the gasification for ceramic firing process [26], the range of 62%-69% using agricultural waste [27], and an average of 65% using briquette fuel from municipal solid waste [18].…”

Biomass is becoming one of the most popular renewable energy sources, especially from agricultural wastes. These wastes can be gasified and utilized in various industries. This experimental study investigated producer gas generation from densified agricultural fuels such as corncobs, rice husks, wood chips, and oil palm fronds in a 50 kW th throatless downdraft gasifier. This system produced combustible gases such as H 2 , CO, and CH 4 , which were utilized as a substitute for diesel fuel in a small diesel engine for power generation. The results showed that the gasifier performs successfully and seems to prefer pellets to briquettes. Producer gas contains 18%-20% carbon monoxide, 1%-6% hydrogen, and 0.9%-1.9% methane. Maximum gasification efficiencies of 53%-71% were achieved with biomass pellets from wood chips, corncobs, oil palm fronds, and rice husks, with producer gas calorific value of 2.94-3.85 MJ/Nm 3 . The average fuel consumption rate was between 6.72-14.43 kg/h, while the producer gas yield was between 2-3 Nm 3 /kg. The average gravimetric concentration of biomass tar in the raw product gas was found to be in the range of 23-50 g/Nm 3 , in which pelletized fuel appeared to show slightly lower tar than briquette fuel. The tar was primarily composed of five compounds: Benzo (a) pyrene, chrysene, pyrene, phenanthrene, 1-methylnaphthalene, and several other polycyclic aromatic compounds. The producer gas from oil palm frond briquettes and biodiesel were tested in a gas engine system in a dual fuel mode. A thermal efficiency of 22.21% was achieved with 2500 W electric load and a 72% biodiesel displacement rate, respectively.

“…These biomass-heating values correspond to the combustion temperature in the gasifier's combustion chamber mentioned above. For comparison, woodchips used as fuel in the development and performance evaluation of a biomass gasification system for ceramic firing process have heating value of about 12-15MJ/kg [18]. It can be concluded that Kanchanaburi province has the potential of producing biomass energy with sources like as corncobs and rice straws that can replace the consumption of LPG gas.…”

This research presents the combustion test of Kanchanaburi’s residue waste used in an 80kW updraft gasifier as biomass fuel. Three types of selected biomass were considered: corncob, bagasee, and straw. The 80kW updraft gasifier was designed, fabricated, and experimentally studied. In the gasifier, a variable speed centrifugal fan acted as a forced convection unit, which was installed near the combustion chamber and transferred air volume to the updraft gasifier stove. The experimental results show the temperature in each zone of the thermochemical processes. The gasifier was evaluated by comparing the performance of the 3 different biomass fuels. The average producer gas from the burning of corncob, bagasee, and straw was 2.31m3/kg, 2.15m3/kg, and 2.11m3/kg respectively in the updraft gasifier. The recorded stove running times (h) for were 1.24, 1.2 and 1.05, respectively. The producer gas can be used to run a local cooking stove kiln with at normal rated heat generation successfully.

“…The process involves evaporation of the moisture contained in the biomass, then the biomass begins to pyrolyze to produce a combustible gas by the complex thermo-chemical reaction. The combustible gas typically contains 16% CO, 12% H2, 3% CH4, 12% H2O (as gas), some higher hydrocarbons (5-6%) and remaining being N2 [11], [12]. The proportion of these components is influenced by the chemical compositions of solid biomass being fed and the operating conditions of the cook stove.…”

This work presents the performance parameters of a solid biomass cookstove for household industrial application to meet the parameters required by the National Standardization Agency of Indonesia (SNI 7926: 2013). The biomass stove design was tested using corncob, coconut shell and wood chips as biomass fuel. Thermal efficiency, combustion efficiency, specific fuel consumption, emission of CO and particulate emissions were evaluated. The combustion temperature, visual flame, combustion air requirement as well as economic evaluation were also studied as additional performance parameters. The average specific fuel consumption rate, Sc of the stove was found 0.57 kg/h. The using amount of biomass variety on this stove could produce the maximum thermal power, Pth of 24,75 kWth and the average combustion efficiency, ηc and the thermal efficiency, ηth of 98.2% and 27%, respectively. The flame temperature of 722-947°C was achieved at equivalence ratio, ф=0.61-0.89. The average CO and particulate production, PM2.5 on this biomass stove were 39.97g/kg and 0.9 g/kg, respectively. The difference of profit margin compared to liquid petroleum gas (LPG) utilization as fuel was about IDR 2,000/kg fish. All these parameters are met to SNI 7926:2013 and corncobs seem the most appropriate biomass fuel on the consideration of this test results.
