Description

Vertical heating stove

The utility model belongs to burning and heat transfer technology field, further relates to a kind of vertical heating stove.

Domestic burners than extensive use mainly contains at present: honeycomb briquette domestic burners and bulk coal-fired domestic burners two big classes.Bulk coal-fired domestic burners is mainly used in small city and rural area, is mainly used to heating and kitchen.The coal heating stove that looses is compared with the honeycomb briquette heating stove has advantages such as easy to use, that fuel is cheap, above-mentioned two kinds of heating stoves of while can directly add water jacket simply and carry out indoor heating, but because of it is not taken all factors into consideration from water circulation, burning, heat transfer aspects, so its effect is all very poor.The civil heating stove of traditional structure adopts simple vertical structure, and flue gas is motion from bottom to top under the draft effect of chimney, with stove in after the heating surface heat exchange of arranging row to atmosphere.The heating stove of vertical structure is at small-power (D＜20KW) be widely adopted in the scope, but, it (is just running into difficulty in the process of the development of D＞20KW) to high-power, because increase along with the heating stove thermal power, the height that certainly will want corresponding increase body of heater to be to arrange more heating surface, still, and to this civil heating equipment, consider the convenience of mounting arrangements, it highly just is restricted.

The utility model purpose is to overcome the shortcoming of above prior art, a kind of vertical heating stove that adopts the interior inclination water-cooled fin structure of stove of augmentation of heat transfer is provided, increased radiation heat transfer area in the stove, strengthened heat transfer, the time of staying of prolong smoke in stove while, strengthen flow perturbation, strengthen the air water heat exchange, adopt fairing cap and built-in tapered outlet flue structure in addition, strict control inner flue gas of the stove flow process, make high-temperature flue gas wash away water-cooled fin and water jacket wall fully, the stove internal heating surface is fully utilized, and energy-saving effect is remarkable.

For achieving the above object, the utility model adopts technical scheme to be: it comprises a housing, be provided with burner hearth in the housing, be provided with water jacket between housing and the burner hearth, the bottom of burner hearth is provided with fire grate and air inlet, upper furnace is provided with inclination water-cooled fin and fairing cap, and the top of inclination water-cooled fin is provided with tapered outlet flue and fire banking-up board.

Burner hearth of the present utility model is built into by refractory cement, has a groove around burner hearth.

The utility model has been avoided significantly increasing the deficiency of body of heater height for increasing the heat exchange amount, under the condition that keeps the limited height of body of heater, has realized the high-power of heating stove, easy to operate, clean hygiene, Remarkable Energy Saving purpose.

Accompanying drawing is a structure principle chart of the present utility model.

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.

Referring to accompanying drawing, the utility model comprises a housing 1, is provided with burner hearth 4 in the housing 1, and burner hearth 4 is built into by refractory cement, is easy to generate hot environment like this and is beneficial to catching fire, burning of the coal cinder that looses; Simultaneously, around burner hearth 4, have a groove 15, can avoid the high temperature coal cinder that hardens to occupy whole section of burner hearth and cause the circulation of air difficulty, between housing 1 and burner hearth 4, establish water jacket 8, housing 1 bottom is provided with the air inlet 2 that communicates with burner hearth 4, the water return outlet 14 that communicates with water jacket 8, the middle part is provided with coal filling hole 5 and the cleaning door 6 that communicates with burner hearth 4, the top of housing 1 is provided with delivery port 9 and the pressure relief opening 11 that communicates with water jacket 8, be provided with fire grate 3 in the bottom of burner hearth 4, the top of burner hearth 4 is provided with inclination water-cooled fin 7, adopt the interior 7 energy time of staying of prolong smoke in stove of inclination water-cooled fin of stove of augmentation of heat transfer, strengthen flow perturbation, strengthen the air water heat exchange, be provided with fairing cap 13 at water-cooled fin 7 middle parts, the top of water-cooled fin 7 is provided with outlet flue 12, in order to prevent that flue gas direct short-circuit row from causing heat energy utilization insufficient to atmosphere, outlet flue 12 is designed to tapered, can strictly control the inner flue gas of the stove flow process, make high-temperature flue gas wash away water-cooled fin 7 and water jacket 8 walls fully, the stove internal heating surface is fully utilized, in outlet flue 12, is provided with fire banking-up board 10.Fire banking-up board 10 is one to be slightly less than the plate object of outlet flue 12 internal diameters, when needs burn, with fire banking-up board 10 rotate to outlet flue 12 axially be parastate; When needs are banked up a fire, fire banking-up board 10 is rotated to and axially the getting final product in vertical state of outlet flue 12.

Operation principle of the present utility model is: the diffusing coal cinder catalytic combustion of wind on air inlet 2 and the fire grate 3, the high-temperature flue gas that produces rises to fairing cap 13, under the guiding of fairing cap 13, wash away the inclination water-cooled fin 7 that is arranged on the body of heater wall, arrange to atmosphere through tapered outlet flue 12 then, the water in the water jacket then is heated and is used for heating.

Easy and simple to handle, the health of the utility model, energy-saving effect is remarkable.
