“…Combustible gas was obtained after 15 minutes of start up, it is suitable with the result was reported by Seggiani et.al and Surjosatyo et.al [19][20]. The mass flow rate of gas was approximately of 80% of total of air and fuel mass flow rate that had same trend with the result Doghru et.al and Kumararaja et.al [18,21].…”

The solid fuel must be converted to gas fuel or liquid fuel for application to internal combustion engine or gas turbine. Gasification is a technology to convert solid fuel into combustible gas. Gasification system generally consists of a gasifier, cyclone, spray tower and filter. This study is purposed to design, construction, and experiment of gasification system. The imbert downdraft gasifier was designed with 42 kg/h for the maximum capacity of fuel consumption, 90 cm for height, 26.8 cm for main diameter and 12 cm for throat diameter. The gasifier was constructed from stainless steel material of SUS 304. Biomass and low rank coal from South Sumatera, Indonesia was used as fuel. The result of the experiment showed that combustible gas was produced after 15 minutes operation in average. The air fuel ratio of low rank coal was 1.7 which was higher than biomass (1.1). Combustible gas stopped producing when the fuel went down below the throat of gasifier.

“…Table 2 shows the composition of the gas as determined under varying air flow rates. The shape and size of the shells were uniform, and even though the density appeared not to be sufficient (˂˂ 200 kg/m3) (Dogru et al 2002) to be used as a suitable feed for an Imbert gasifier (throated downdraft gasifier), but it worked in this throatless downdraft gasifier without any flow problems.…”

“…In this study, the experiments were carried out in the pilot gasification plant consisting of a throated down-draft gasifier and a gas clean-up unit placed before the sample port. Fixed bed gasifiers are simple to use and downdraft gasifiers have been successfully used in other bio-fuels to generate a cleaner producer gas than other fixed bed systems (Dogru et al 2002, Midilli et al 2001. While, the specific objective is to carry out a fuel characterization of the producer gas generated from the closed-top throatless downdraft gasifier using groundnut shell fuel.…”

Abstract:In this paper, gasification potential of biomass residue was investigated using a laboratory scale throatless downdraft gasifier. Groundnut shells gasified in a throatless downdraft gasifier could be used to produce a clean gas with a calorific value of 5.92 MJ/Nm3 and a combustible fraction of 45% v/v. Low moisture (8.6%) and ash content (3.19%) are the main advantages of groundnut shells for gasification. Gasification of shell waste products is a clean energy alternative to fossil fuels. The product gas can be used efficiently for heating and possible usage in internal combustion engines.
