Abstract
The utility model discloses a fire cover of a burner, which comprises a disc-shaped fire cover body, and a ring-shaped vent groove is arranged at the bottom of the fire cover body. The fire cover is characterized in that the fire cover body is provided with a plurality of through gas spray holes which are penetrated through the upper surface of the fire cover main body, are communicated with the ring-shaped vent groove and have the shape of an annular array, and the horizontal projection of the axes of each gas spray hole is intersected to form the concentric circle of the fire cover body; and the side wall of the inner ring of the fire cover body is provided with a transition inclined surface which spreads to the upper surface of the fire cover, the fire cover body is provided with the through gas spray holes which are penetrated through the transition inclined surface, are communicated with the ring-shaped vent groove and have the shape of the annular array, and the horizontal projection of the axes of each gas spray hole is intersected to form the concentric circle of the fire cover body. The fire cover has the advantages of being simple in structure, and convenient in machining and installing, and being capable of effectively improving the burning efficiency.
Description
[technical field]
The utility model relates to the gas burner field, is specifically related to a kind of burner fire lid.
[background technology]
Burner fire lid is to be used to be installed in burner parts topmost, since above be provided with a plurality of fumaroles, when burner operation, the ejection in the fumarole of the combustion gas behind the premix for the first time mixes under the effect that is incorporated in igniter for the second time with air lights, thereby realizes the purpose of heating.Burner fire lid structural design on the market is reasonable inadequately at present, causes the efficiency of combustion of combustion gas not high, thereby the energy is not effectively utilized.The utility model is researched and developed under this background.
[utility model content]
The purpose of this utility model is in order to solve the problems of the technologies described above, and proposes a kind of simple in structurely, processes easy for installationly, can effectively improve the burner of efficiency of combustion.
For solving the problems of the technologies described above, the utility model adopts following technical proposal:
A kind of burner fire lid, include discoid fire lid body, fire lid body bottom is provided with the ring-type air channel, it is characterized in that described fire lid body be provided with penetrate its upper surface, be conducted with the ring-type air channel, the some straight-through fumarole of circular array, the axis of each fumarole intersects the concentric circles that forms fire lid body in the projection of horizontal plane; The interior ring-side wall of described fire lid body is provided with the transition inclined-plane that warms oneself in front of a fire and cover surface spreading, fire lid body is provided with and penetrates the transition inclined-plane, is conducted with the ring-type air channel, the some straight-through fumarole of rounded array, and the axis of each fumarole intersects the concentric circles that forms fire lid body in the projection of horizontal plane.
Further design, the described some straight-through fumarole that penetrates fire lid body upper surface, its axis extends and horizontal plane shape-75 ° of angles at 45 downwards; The described some fumaroles 104 that penetrate the transition inclined-plane, its axis extend downwards with horizontal plane and form 15 ° of-45 ° of angles.
Further design, the described some straight-through fumarole that penetrates fire lid body upper surface, its axis extends downwards with horizontal plane and forms 60 ° of angles. The described some fumaroles that penetrate the transition inclined-plane, its axis extend downwards with horizontal plane and form 30 ° of angles.
The beneficial effects of the utility model are: unique fumarole design, the fuel gas mixture of ejection can fully burn, and has improved efficiency of combustion greatly, therefore not only energy-saving effect but also good.
