“…Many researchers had pay attention to higher thermal efficiencies and lower emissions of domestic gas burner since the increasing demand for energy saving [3,5,[8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The modified high pressure gas burner was improved the angles of outer and inner ports and the numbers of outer and inner ports, which affect the thermal efficiency.…”

Abstract. The KB-5 high pressure gas burners were popularly and widely used in Thailand. This research was aimed to study the influence of four significant parameters, namely degrees of outer and inner ports and the number of outer and inner ports of high pressure gas burners, to the thermal efficiency by the experiments. The thermal efficiency was tested with reference to the standard industrial stoves in household with liquid petroleum gas (TIS 2312-2549). The results were shown the increasing angles of the outer port increased 13% thermal efficiency, the increasing numbers of outer port increased 5% thermal efficiency and increasing the numbers of inner port increased 7% thermal efficiency from the factory's model. The increasing angles of inner port had less effect on thermal efficiency. The improving of high pressure gas burner will have modified by increased the numbers of outer and inner port and the angles of the outer port for the higher thermal efficiency than the factory's design.

“…For extensive arrays of closely spaced ports con"guration, a single inner cone covers all of the ports and is stabilized at the edge of the port array. This phenomenon was avoided during the modi"cation of the proposed SB from the original one proposed by Tamir et al (1989) so as to maintain the #ame stability. Flame structure and interaction of the swirling central #ame of the SB are visible in Figure 8.…”

“…the weight of the CS is about 561 g, whereas that of the LCS is 151 g. The NS is similar to the LCS except that the bottom area of the NS is formed by a stainless-steel wire mesh (with a mesh size of 16 mesh in\) which serves as a porous medium instead of opaque sheet metal. The SB is made of carbon steel and is modi"ed from the work of Tamir et al (1989) by increasing the port area to suit the #ame characteristics of the fuel used in the experiment. Lique"ed petroleum gas (LPG) (containing C H 40 per cent and C H 60 per cent by vol.)…”

“…This is merely done by replacing the radial #ow slotted-ring burner of the CB with the proposed swirling central #ame ring burner (or SB) without major alterations of the other burner components. Based on the fundamental data obtained by Tamir et al (1989), an additional modi"cation in the number of ports of the burner was done so as to improve the combustion characteristics, since the types of fuel used were di!erent. The performance of the gas cooker with the SB was evaluated by comparing its thermal e$ciencies with that of the CB.…”

“…E!orts have been made so far for improvement in thermal e$ciency of gas cooker. Tamir et al (1989) performed, according to the British Standard, experimental studies on characteristics of a gas burner with a swirling central #ame (hereafter referred to as a swirl burner, SB), using synthetic gas and natural gas. Various parameters expected to a!ect the thermal e$ciency (de"ned as the ratio of heat absorbed by a vessel being heated to the combustion heat of the gaseous fuel) were explored.…”

SUMMARYThe present study proposes a swirling central #ame technique to improve the thermal e$ciency of a conventional open-#ame atmospheric gas cooker which is now widely used as a domestic appliance. More extensive studies were done in an e!ort to improve the thermal e$ciency of the cooker by reducing thermal inertia of the pan support and using the proposed porous medium technology to recover heat from #ame radiation to preheat the secondary air entrained from the bottom of the burner. The experimental results showed that the thermal e$ciency of the swirling central #ame burner with conventional support is approximately 15 per cent higher than that of the conventional radial #ow burner. This can be attributed to the higher heat transfer coe$cient between hot #ue gas and vessel surface of the swirl burner than that of the conventional one. By replacing the conventional support of the developed swirl burner with a lighter one, whose mass was reduced by a factor of 3.7, the thermal e$ciency could be increased by about 3 per cent. By using the proposed preheating secondary air support instead of the light support, the thermal e$ciency could be further improved by 3 per cent. The predicted thermal e$ciency obtained from the proposed model showed good agreement with the experiment.
