Abstract
The Energy Policy and Planning Office, Ministry of Energy, Royal Thai Government reported from 2007 to 2015, the using of fuel increase every year. In addition, price of fuel increases continuously. The way of most efficiently of energy using is important. This paper aimed to study about thermal efficiency of infrared gas stove by varies with parameters which were diameters of pot (220, 240 and 260 mm), distances between burner (20, 25 and 30 mm) and pot and diameter of burner head (135, 145 and 155 mm) in 9 cases by simulation method. The numerical model was validated with results from experiment in 220, 240 and 260 mm of diameter of pot, average errors are 10.85011%, 6.754703% and 2.13054%, respectively. The results of this study showed with three sizes of pot, huger distances between burner and pot decrease thermal efficiency. The highest thermal efficiency was in 260 mm of diameter of pot. All of 9 cases by vary parameters, the highest thermal efficiency was 260 mm of diameter of pot, 20 mm of distance between burner and pot and 145 mm of diameter of burner head condition and the lowest thermal efficiency was 220 mm of diameter of pot, 20 mm of distance between burner and pot and 145 mm of diameter of burner head condition. The obtained results provide useful for development of heating process by infrared burner technologies and to guide the development of effective infrared burner too lead the way in energy-saving way and reduce environmental impacts.
