Abstract

The utility model relates to a collision internal flame reflection type burner of range, which is composed of a burner body, a wind regulating board, a nozzle, a fire hole cover and a liquid filling plate. The tapered part of the burner body is provided with a radiant panel which is provided with radiation grooves and a concave cambered surface, and the upper part is provided with a collision type fire hole cover, the fire holes of which are across arranged in pairs. The utility model has the advantages what the atmosphere type burning and infrared burning have and belongs to a novel burner of range which overcomes the defect of the existing burner of range. The combustion efficiency is enhanced, and the CO content in flue gas is lowered. In addition, the flame temperature reaches 870 DEG C to 1160 DEG C, and the heat efficiency reaches 70% to 75%.

Description

Collision internal flame reflection type burner of range

The utility model relates to the improvement of gas kitchen ranges, existing gas kitchen ranges, diffusion type, air suspended type are arranged and do not have three kinds of gas kitchen ranges of flame-type (being infrared-type), the most widely used is air suspended type, its shortcoming is an incomplete combustion, cooker is had pollution, and still have 20% heat to lose with flue gas, the thermal efficiency has only 55%-60%.Though and infrared kitchen range burning is more abundant, just may cause tempering when surface temperature is higher than 1050 ℃, radiation efficiency descends when being lower than 850 ℃, thereby thermic load can not regulate arbitrarily, toasts very extensively so be used for heating, is used as kitchen range and only is applicable to and heats up water.

The purpose of this utility model just provides the advantage that the reflective gas kitchen ranges of a kind of internal flame that clashes can have above-mentioned existing gas kitchen ranges concurrently, overcome a kind of gas stove of its shortcoming, it further improves combustion thermal efficiency, CO content in the flue gas reduces greatly, temperature further improves, and is pollution-free to kitchenware.

Technical solution of the present utility model is by burner body (4), air regulating board (5), nozzle (6) and fire hole cover (3), drip pan (2) is formed, it is characterized in that: dispose the radiant panel (1) of band radioactive ray groove and cancave cambered surface in the tapering of burner body (4), and have the collision type fire hole cover (3) of paired cross arrangement fire hole in the assembling of the top of burner body (4).

The utility model has overcome the deficiency of existing gas kitchen ranges, fire hole is arranged in intersecting, burned flame is collided in pairs, show through the temperature measuring of thermocouple the diffusion type combustion flame, existing gas kitchen ranges flame temperature is 300 °---900 ℃, and the utility model kitchen range is that 870 ℃ of-1160 ℃ of thermals efficiency reach 70-75% through the head-on collision flame temperature.This becomes possibility for the development and use of fuel gas with low heat value, and the utilization of existing combustion gas has been improved the thermal efficiency, cuts down the consumption of energy.

Below to description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3, Fig. 4 are respectively the front view and the cutaway views of the utility model fire hole cover;

Fig. 5 is the structural representation of above-mentioned figure (3) fire hole part;

Fig. 6, Fig. 7, Fig. 8 are respectively the front views of radiant panel, cutaway view and A-A profile.

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Part (1) is a radiant panel in figure (1), part (2) is the drip pan that becomes one with loam cake, part (3) is the collision type fire hole cover, part (4) burner body and induction tunnel, part (5) is an air regulating board, part (6) is a nozzle, combustion gas sucks primary air and gives mixing earlier in pipe by induction tunnel and afterwards enters burner when using, fire hole from the collision type fire hole cover sprays again, combustion-supporting additional auxiliary air is imported by fire hole cover top, light back high temperature head-on collision flame by the cancave cambered surface internal combustion of fire hole to radiant panel (1), the infrared ray heating cooker bottom that the burning back is scorching hot, head-on collision fire hole cover (3) wherein diameter D and garden cone angle will match with burner body (4) and not leak, and the α angle is that combustion gas imports the angle.And the fire hole angle of the crossing θ and the spacing δ that scheme expression in (5) can be according to the different values with fire hole quantity of fire hole cover size between 10 °-120 ° and between greater than 1-10mm.And multiple spread pattern is arranged.

Fig. 6, Fig. 7, Fig. 8 are radiant panel (1) structures, and radioactive ray direction groove and cancave cambered surface are arranged above, and to increase the area of dissipation of radiant panel, radiant panel (1) adopts the higher material sintering of radiation coefficient to form.The utility model adopts the enclosure fire hole inside, make the top process of combustion-supporting auxiliary air by fire hole cover (3), absorb the fire hole cover waste heat and become the auxiliary air that gives heat, be directed at around the fire hole by curved surface again, make burning have enough auxiliary airs to replenish, no matter be flame up or down, the burning of enclosure internal flame is more concentrated than outer ring combusting firepower, heat scatters and disappears still less.

Adopt infrared radiation panel (1) reflection shown in Fig. 6,7,8 to make burning more complete.In sum, the kitchen range of the head-on collision internal flame reflective structure of present patent application have made full use of internal flame atmospheric burning type in the fuel gas buring process and have been aided with radiant panel again and make by atmospheric burning type and change flameless combustion into, send infrared reflection to the cooker bottom, therefore thermic load can be regulated, the monoblock radiant panel is sent scorching hot infrared ray by high-temp combustion when thermic load is big, and when thermic load is turned down, the radiant panel part is by high-temp combustion, promptly send a circle infrared radiation heat, when the thermic load accent is very little, promptly become atmospheric burning type, rationally adopt combustion system automatically like this, burn fully rationally for cooker.

In not super the utility model claim protection domain, those skilled in the art can have multiple structure Design and improvement in a word.
