“…Due to the eclectic amount of highly appealing characteristics of gasifier cookstoves, including high efficiency, smokefree safe combustion, uniform and steady flame, simplicity of controlling the flame, and operational capability for long periods (Raman et al, 2014), the advancement of gasifier cooking stoves became significant. Therefore, to date, several research studies had been performed on the design and development of gasifier cooking stoves with the goal of increasing efficiency and dwindling emission such as producer gas stove with bluff-body shape in burner (Susastriawan et al, 2021), producer gas stove (Panwar et al, 2011;Punnarapong et al, 2017), Chinese gasifier stove (Carter et al, 2014), naturaldraft gasifier cookstoves (Hailu, 2022;Tryner et al, 2014), fixed bed advanced micro-gasifier cook stove (Sakthivadivel & Iniyan, 2017), inverted downdraft gasifier (Narnaware & Pareek, 2016;Ojolo et al, 2012;Osei et al, 2020), biomass gasifier cookstove (Panwar & Rathore, 2015), top-lit updraft gasifier cookstove (Scharler et al, 2021), advance microgasifier stove (Sakthivadivel et al, 2019;Wamalwa et al, 2017), rice husk gas stove (Ndindeng et al, 2019), natural and force draft gasifiers stove (Getahun et al, 2018), and natural cross draft (Nwakaire & Ugwuishiwu, 2015). However, to the authors' best knowledge, no proper systematic reviews have already been conducted on the overall thermal performance of gasifier cook stoves, with an emphasis on types of gasifier stoves, cooking fuels, location of investigation, and materials to fabricate stoves.…”
