Abstract

Objectives: The objective of this review was to study various works that have focussed on the improvement of the efficiency and emission features of the LPG (Liquified Petroleum Gas)cook-stoves. Methods: The major focus of the review was on the LPG cook-stoves, though a variant in the form of Biogas was also studied. Parameters like performance, efficiency and emission features of various cook-stoves were taken into account. The design factors of the burners used in these cook-stoves was also one of the major factors that was strongly emphasized in this study. Findings: It was found that if the efficiency of a stove needs to be improved, the focus must be on the improvement of the specifications, design and material of the burner. For better efficient burners, the air preheating can be considered as a factor. As in the case of porous media, the thermal efficiency of the burner increases and the CO and NOX emissions reduce drastically. Application: Material of the burner also plays a pivotal role in the performance of the stove. Burners made up of have been found to be more efficient than their counterparts iron burners. Also, the shape of the burner is one factor that can help improve the performance of the stove.
