“…The moisture content of cow dung is high, which drains much of the deliverable energy from a gasification plant, since part of the energy is used to evaporate the moisture which is not recovered. This important input design parameter must be known for the assessment of the cost of energy for drying the cow dung as well [8]. Therefore, it is one of the criteria for the selection of energy conversion technology.…”

“…In gasification processes, it is vital to reduce the moisture content of dung fuel. High moisture contents will reduce thermal efficiency since the heat is used for drying purpose [8]. To determine the moisture content of cow-dung, we dried the weighed amount of sample in an open crucible-plate which is kept at 105℃ for 24 hr.…”

Biomass energy is the most important primary energy sources in Ethiopia, above 90% of primary energy comes from biomass. Cow dung is one of the widely consumed biomasses as a source of energy in rural areas of Ethiopia in traditional and inefficient cook stoves. To this end, this piece of research work is aimed at designing, manufacturing and experimentally testing its environmental and energy performance compared to the traditional three-stone stove. In this study water boiling test and control cooking test was used to investigate the performance of stoves. The proposed gasifier stove shows a better performance than three stones stove when water-boiling test conducted in terms of cooking duration, specific fuel consumption, and pollutant gases emission. The experimental results revealed that gasifier stove has shown an increase of thermal efficiency by 26.6% and reduced PM2.5 and CO emission by 58.9% and 88.6% respectively as compared to the traditional three-stone cook stove. Furthermore, the gasifier stove has shown 64% fuel saving efficiency as compared to the three stones stove and 54% cooking time saving to cook the same amount and kind of meal. In every aspect of the measuring parameters whether the energy efficiency performance or environmental performance the designed gasifier stove performs better than the traditional three-stone cook stoves. Therefore, with a small and simple modification, the gasifier stove could be disseminated to the rural community of the region in collaboration with the regional bureau.

“…The cow dung fuel was selected as a fuel source due to its availability, low cost, and easily piled in the home within a small area for further use in Ethiopia [1]. The gasi er reactor haddesigned and fabricated to meet the cooking energy requirement of vefamily members [9].The stove was designed using important parameters that need to be considered to determine the appropriate size of the cow dunggasi er reactor, taking into consideration the thermal energy output or the output temperature required [2].In order to minimize heat losses, critical insulation thickness of material from ash was calculated during size and dimension analysis of gasi er section.The experiments were conducted on a fabricated gasi er stove and three-stonetraditional cook stove. The emission reduction and the thermal e ciency of the stove was evaluatedwith Water boiling test and control-cooking test,and Indoor Air Pollution Monitoring equipmentrespectively.…”

“…The product gas mixture's heating value ranged from 4.1 to 4.4 MJ/Nm 3 , while the gasifier's cold gas efficiency, carbon conversion efficiency, and specific gasification rate were in the range of 57 to 59 percent, 95 to 97 percent, and 103 to 109 kg/h-m 2 , respectively. Preetha Devi and Kamaraj [4]designed a pilot scale updraft gasifier by using various biomass as feedstock such as wood chips, coconut husk etc. at used weight of 30kg.…”

India has large proven reserve of coal but most of the coal has large quantity of ash. Utilization of this high ash content coal is again a verychallenging task. Presently, gasification of high ash coals has not yet been in application due to the difficulties arising from the ash handlingprocesses. In this work an attempt was made to design a partially fluidized bed reactor that can handle 30 kg/hr coal as a feedstock. By usingan appropriate design procedure a complete design of a hybrid gasifier was studied deeply. The major aim of present research is todetermine the air flow rate for proper gasification, reactor diameter and reactor height, feed particle diameter, nozzle orientation and numbernozzles, reduction zone diameter and height. Experiments were carried out with feeding rate of 9.8 kg/hr with high ash content coal having39.83% ash. Satisfactory results have been found during experiments. The average producer gas generation during trial run was found to be29.8 Nm3/hr while average calorific value of producer gas was about 4500 kJ/Nm3. The work described here favours us understand the realgasification process for high ash content coal and thus facilitates the industrial application of gasification technology.
