Abstract

The utility model relates to an energy-saving stove with a honeycomb ceramic structure. The stove comprises a furnace ring internally provided with an exhaust channel, a hearth and a furnace core in the hearth. The honeycomb ceramic structure is an inverse circular truncated cone. The lower end of the structure is circularly connected with a combustion plate of the furnace core, while the other end is circularly connected with the inner surface of the furnace ring. The hearth is divided into an outer heater and an inner hearth. Through holes penetrating through up and down are uniformly distributed on the honeycomb ceramic structure. Smoke generated by combustion of the furnace core passes through the honeycomb ceramic structure and is discharged from the exhaust channel in the furnace ring, so that the stroke for discharging smoke is prolonged, and the speed for diffusing smoke is alleviated. Heat generated by combustion is adequately converted into radiant energy which is then used to heat the boiler body, so that the heat energy utilization ratio of gas is improved, and the temperature of discharged smoke is reduced.

Description

A kind of energy-saving stove

Technical field

The present invention relates to a kind of large-scale energy-saving gas furnace for dining room, restaurant.The energy-saving gas stove that specifically has infrared ray ceramic honey comb structure.

Background technology

The heating principle of tradition stove and accessory is come at the bottom of the heating kettle by the direct combustion fuel of atmosphere.Such mode of heating, though also can reach the purpose of food in the heating kettle, because flame can overflow from the space between the bottom of a pan and stove and accessory, flame is not fully utilized, thereby has caused the waste of energy.

Utility model patent: a kind of energy-saving stove, the patent No.: 200620140985.9 disclose a kind of energy-saving stove, this energy-saving stove comprises and being located on the body of heater in order to support the edge suitable for reading, kitchen range chamber of pot body, be in the burning air blast burner of middle part, kitchen range chamber, edge suitable for reading, kitchen range chamber is the sealing ring surface that is complementary with described pot body, and the burning air blast burner outer shroud of telling is equipped with the insulating made from far-infrared ceramic material, surface distributed at this insulating has a plurality of through holes, and formed cavity is provided with the exhaust outlet that is connected with the stove and accessory discharge flue between this insulating and the described kitchen range chamber simultaneously.

Form sealing surface between the edge suitable for reading, kitchen range chamber of this energy-saving stove and the pot body, therefore, behind the fuel gas buring, waste gas and unnecessary heat can't be overflowed from the space between edge suitable for reading and the pot body, and can only return downwards, discharge from each through hole of cover body, simultaneously, insulating absorbs the waste heat in the waste gas rapidly again and heats self.Our experiments show that, can promptly be down to below 700 ℃ through the EGT behind the through hole, and the insulating after being heated is given the bottom of a pan thermal energy transfer in the mode of infrared radiation again, thereby improve the heat energy utilization rate.But also there is the improved place of needs in this energy-saving stove, very fast such as the exhaust gas velocity of discharging, the EGT of discharging is higher, also there is a large amount of heat energy in the waste gas of discharging, if toxic emission speed can be reduced, heat energy in the waste gas just can be more by the utilization of pot body, and the heat energy utilization rate of combustion gas also will improve.

Summary of the invention

Technical problem to be solved by this invention is at above-mentioned prior art present situation, and provide the energy-saving gas stove with ceramic honey comb structure of the built-in discharge flue of a kind of stove circle, discharge from the built-in discharge flue of stove circle again after the flue gas process ceramic honey comb structure that combustion chamber burning back produces, prolonged the stroke of fume emission, slowed down the speed of flue gas diffusion, the heat that burning is produced fully is converted to radiant energy heating kettle body again, improve the heat energy utilization rate of combustion gas, reduced the temperature of discharging flue gas.

The present invention solves the problems of the technologies described above the technical scheme that adopts: the energy-saving stove with ceramic honey comb structure of the built-in discharge flue of a kind of stove circle comprises the stove circle, burner hearth, the combustion chamber of burner hearth inside.

The ceramic honey comb structure is reverse frustoconic, the burner plate of lower end articulating combustion chamber, and the inner surface of upper end articulating stove circle is separated into outer burner hearth and internal furnace two parts with burner hearth.

Stove circle integral body is " n " shape, and by inner surface, upper surface and outer surface are formed, and stove circle inner hollow leaves discharge flue on the outer surface; The stove circle forms the sealing ring surface that is complementary with the pot body.

The hearth wall upper end is connected with stove circle intimate, leaves the space between hearth wall upper end and stove circle inner surface and the stove circle upper surface, and the space is connected with internal furnace.Be uniform-distribution with the through hole of up/down perforation on the ceramic honey comb structure.The flue gas that burner hearth burning outside produces enters internal furnace through the ceramic honey comb structure, again by the space between hearth wall and the stove circle, by the discharge flue on the outer vertical plane of stove circle gas fume after burning is discharged at last.This process has delayed the speed of flue gas diffusion greatly, has improved the heat energy utilization rate of fuel.

The specific embodiment

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

As shown in Figure 1-Figure 3, the space between burner plate, 5 hearth walls and the stove circle of 1 burner hearth, 11 outer burner hearths, 12 internal furnaces, 13 hearth walls, 2 ceramic honey comb structures, 3 stove circles, 31 stove circle upper surfaces, 32 stove circle inner surfaces, 33 stove circle outer surfaces, 4 combustion chambers, 41 combustion chambers top, 6 pots of sealing ring surfaces that are complementary that body, 7 discharge flues, 8 stove circles and pot body form.

The energy-saving stove of present embodiment comprises ceramic honey comb structure 2, stove circle 3, burner hearth 1, the combustion chamber 4 of burner hearth inside.

Ceramic honey comb structure 2 is reverse frustoconic, is spliced by the ceramic honey comb plate of 10-12 sheet specification unanimity, is easy to I﹠M.The burner plate 41 of the ceramic honey comb structure lower end articulating combustion chamber 4 of reverse frustoconic, the inner surface 32 of upper end articulating stove circle 3 is separated into outer burner hearth 11 and internal furnace 12 two parts with burner hearth 1.Be uniform-distribution with the through hole of up/down perforation on the ceramic honey comb structure 2.The below of ceramic honey comb structure 2 is equipped with the supporting construction of resistant to elevated temperatures band mesh.

Stove circle 3 integral body are " n " shape, and by inner surface 32, upper surface 31 and outer surface 33 are formed, and stove circle 3 inner hollow leave discharge flue 7 on the outer surface.Stove circle 3 forms the sealing ring surface 8 that is complementary with pot body 6.Discharge flue 7 is made up of 8-12 circular hole, and all Circularhole diameter unanimities are evenly distributed on the same horizontal plane.The diameter of each circular hole is between 5mm-15mm.

Hearth wall 13 upper ends closely are connected with stove circle outer surface 33, and and leave space 5 between stove circle inner surface 32 and the stove circle upper surface 31, space 5 is connected with internal furnace 12.The flue gas that burner hearth burning outside produces enters internal furnace through the ceramic honey comb structure, by space 5, by the discharge flue 7 on the stove circle outer surface 33 gas fume after burning is discharged at last again.This process has delayed the speed of flue gas diffusion greatly, has improved the heat energy utilization rate of fuel.
