Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0016] Such as Figure 1-3 As shown, the secondary air direction simulation observation system of the embodiment of the present invention includes a metal ring 1 whose diameter is greater than the outer diameter of the air mixing chamber of the burner 10 of the stove, and the diameter of the metal ring 1 The diameter difference from the outer diameter of the gas mixing chamber is 30mm-90mm. And the metal ring 1 can also be replaced by other metal rings, such as a square metal ring, or an oval metal ring, as long as it is a metal ring, and the inner diameter is greater than the outer diameter of the gas mixing chamber, it can be placed outside the gas mixing chamber. Can. Moreover, the metal ring can also be formed by splicing multiple segments that are not connected to each other, or it is only necessary to place multiple segments directly o...

The invention discloses a fuming device for a gas stove and a secondary air moving direction simulation observation system with the same. The fuming device comprises a metal ring, and the inner diameter of the metal ring is larger than the outer diameter of an air mixing chamber of a stove combustor. The fuming device is characterized in that a heating belt is evenly wound around the outer side of the metal ring, a wire of the heating belt is connected to a temperature control device, a thermocouple is arranged on the outer side of the metal ring in a contact mode, the thermocouple is connected to the input end of the temperature control device through a wire, and fuming oil is evenly smeared on the heating belt; the fuming device further comprises a projector which can generate yellow light and irradiates the yellow light to the metal ring. According to the fuming device for the gas stove and the secondary air moving direction simulation observation system with the same, the effective equipment and structure are adopted for achieving accurate simulation of secondary air flowing and moving direction, visual inspection is facilitated, and the quite important guiding function is achieved on development of the gas stove. The fuming device is stable and controllable, and further qualitative and quantitative analysis research is facilitated.
Description
technical field [0001] The invention relates to a smoke generating device for a gas cooker and a secondary air trend simulation observation system with the device. Background technique [0002] With the development of the city gas industry, my country's stove industry has greatly improved in terms of variety, material, performance, sales, etc., and a very important point in its performance improvement is the improvement of thermal efficiency. The burners of domestic gas stoves are mostly atmospheric burners, and the atmospheric burners are designed according to the partial premixing method, and their primary air coefficient is 0<α<1. The atmospheric burner is divided into two parts: the head and the ejector. The ejector is used to eject the primary air required for combustion, and the function of the burner head is to evenly distribute the mixture of gas and air to the fire hole for stable and complete combustion. The primary air coefficient α of the atmospheric burn...
