Effect of Different Surface Types of Loading Vessel Wall on Combustion Performance of a Domestic LPG Cook Stove

Liquefied petroleum gas is commonly used for cooking purposes as it has high energy content and less pollutant. In this work, the effect of different surface types of loading vessel on the thermal efficiency of the stove has been studied with the help of computational fluid dynamics analysis. The 3003-grade alloy of aluminum and 304/316 grade of stainless steel are considered for the loading vessel wall as these materials are generally used for cooking utensils. Different surface types, mainly polished, oxidized, and anodized, of the materials are also studied with changing emissivity of the materials. Materials with polished surfaces are provided lower thermal efficiency as compared to the oxidized or anodized surfaces. Maximum thermal efficiency is found for stainless steel with oxidized/anodized surface of the cooking vessel.
