Problems solved by technology
[0003] In order to overcome the low heat utilization rate of gas and oil stoves used now; the exhaust gas of domestic gas stoves is still scattered indoors, which is both hot and hinders people's health. The gas and oil stoves of the present invention have taken the following five technical measures: 1. set Warmers such as figure 1 Shown in the picture, what draw among the figure is soup pot, and warmer 1 is stamped by thin steel plate, and it is a shape similar to pot shape and the other part that surrounds the latter inside, its top seals and leaves such as figure 2 As shown, there are three air inlets evenly distributed at 120°. The middle part is an inner and outer jacket composed of three layers of thin plates. The spacer plate 10 divides the air flowing from the inlet 14 into two streams. The inner jacket has more air, and the outer jacket has more air. Less, the bottom is a single jacket composed of two thin steel plates, from which air enters the burner embedded in its center

Embodiment Construction
[0012] What this specific embodiment narrates is that the cooking utensil is a domestic gas stove with a traditional soup pot. The maximum oil gas volume is 0.14KG / H, the maximum air volume is 2.9KG / H, which is 1.63KW, and the effective heat obtained is 4924KJ / H. It is equivalent to the effective heat of the domestic gas stove currently used with a petroleum gas volume of 0.28KG / H and 3.26KW. And cooking utensils are household gas stoves of frying pans and canteens with gas, the implementation situation of oil stoves is similar to this, so do not repeat them one by one.
[0013] according to figure 2 The insulator can be processed by the canning process. The thickness of the plate is 0.4mm. The inner surface of the insulator made of heat-resistant steel must match the shape of the pot and be 2mm larger than it. The diameter of the inner surface of the insulator in this example is 224mm, the spacer plate 10 divides the insulator into two jackets, S=6mm, T=2mm, and divides the...

The invention relates to a kind of gas oil oven of which the heat utilization exceeds 84%. It concludes an enclosed fire tank which is formed by a cooker tackle, a seal oven ring, a heat retainer, air fore-warmer. The shapes of heat retainer and air fore-warmer are similar with the shape of cooker tackle. The heat retainer packs the cooker tackle in it and then the air fore-warmer packs the heat retainer in it so the fume flow in the narrow parallel and curved face runner which is enclosed by the lays. The heat of the fume besides delivers to the cooker tackle it can deliver to the heat retainer and air fore-warmer. The air of the heat retainer and air fore-warmer further bring the heat to the fire tank and then delivers to the cooker tackle at last the fume with none heat is lead to the oil pumping fume machine then discharged to the outdoor. The adopted fuel-air is match to the synchronization governor valve which is a same valve shaft and double windows matched synchronization governor valve. The try-on result of oven is that: the heat utilization exceeds 84% and the fume isn't drift in the chicken.
Description
Technical field: [0001] The invention relates to a gas and oil stove, in particular to a gas stove with energy-saving and environmental protection measures such as increasing the heat absorption of the pot, recovering exhaust heat, and burning with the best excess air coefficient. Background technique: [0002] At present, the gas and oil stoves used in canteens are "strong wind mixing and closed combustion". The unreasonable points are: ①The potential of the heating surface has not been fully explored, and ②The exhaust heat has not been fully recycled. The domestic gas stove is "injection mixing and open combustion", which is unreasonable: ① a large amount of cold air flows in from the bottom of the burner, mixed into the gas, so that the excess air coefficient increases and deviates from its Optimum value, ②The heating surface is not fully utilized, ③Exhaust heat cannot be recovered. Because these unreasonable parts lead to the gas that uses now, oil stove has following s...
