Abstract

The utility model relates to a heating stove by using honeycomb briquet, which is characterized in that a heat exchanger is arranged in a flue insulating layer, the heat exchanger forms a flue-type water jacket by a housing and an inner container, the upper slope and the lower slope of the flue-type water jacket form an angle with 45 DEG, the housing water jacket at the top end of the upper slope is communicated with a water outlet pipe, the housing water jacket at the bottom end of the lower slope is communicated with the water outlet pipe, heat exchange pipes which are inclined at 45 DEG are arranged in a flute which is formed by the inner container, the heat exchange pipes which are arranged in parallel and in a stagger way are communicated, and both ends of the heat exchange pipes are communicated with the housing water jacket. The utility model has the advantages that the heat exchanger is arranged in the flue, the heat exchange pipes are arranged in an inclined way, bringing water to be heated to expand and ascend, and the water is pressed in the water outlet pipe. The utility model has high heat efficiency, and is suitable to a domestic heating honeycomb briquette stove.

Description

The honeycomb briquette heating stove

The utility model belongs to the home furnace of application of solid fuels, particularly a kind of honeycomb briquette heating stove.

At present, honeycomb briquette stove not only is used for culinary art, and can be used for heating, and concrete structure is that the water thermic devices of guaranteeing replacement is set around the body of heater, or around the fire door heat-exchanger rig is set above body of heater, directly draws the body of heater heat, converts hot water to, is used for hot water heating.Because the configured and disposed position of heat-exchanger rig is unreasonable, cause cold and hot interior circulation not smooth, the heat exchange effect is relatively poor.

The purpose of this utility model is, designs and produces a kind of honeycomb briquette stove, and the hot water heat-exchanger rig is set in flue, to make full use of burner exhaust heat, realizes hot water circuit heating, improves the honeycomb briquette stove heat exchange efficiency.

Honeycomb briquette heating stove of the present utility model, by body of heater, the combustion chamber, chimney is formed, in insulating layer of furnace body, be provided with vertical secondary oxygen supply air channel around the combustion chamber, it is characterized in that in the flue heat-insulation layer, being provided with heat exchanger, heat exchanger forms the chimney flue type water jacket by shell and inner bag, on, under form 45 the degree inclined-planes, shell water jacket at the most significant end of upper inclined surface is connected with outlet conduit, in the formed flue of inner bag, be provided with staggered being arranged in parallel, the heat exchanger tube that the inclination miter angle connects, the heat exchanger tube two ends are connected with wall of inner container, communicate with the water jacket of shell, be connected with water return pipeline at the shell water jacket of the least significant end of chimney flue type water jacket lower bevel.

The section configuration of chimney flue type water jacket has rectangle or circle.

Using method of the present utility model is when filling with water in heat exchanger water jacket and the heat exchanger tube, to open fire door, put into the honeycomb briquette burning to the combustion chamber, the oxygen of combustion chamber is provided by the fire door of opening, and a part is without the gas of burning, and it is combustion-supporting to carry out the secondary oxygen supply by secondary oxygen supply air channel; The high-temperature flue gas of burning enters the flue that heat exchanger central authorities inner bag forms by flue, heats the oblique heat exchanger tube that is covered with, and the water expanded by heating in the heat exchanger tube upwards is pressed into outlet conduit, provides heating to use; Simultaneously, the water of water return pipeline enters heat exchanger, to replenish the water that extrudes because of expanded by heating, causes circulation according to this.Enter heat exchanger by the high hot flue gas of the high temperature of combustion chamber, carry out cold and hot exchange after, flue-gas temperature reduces, and is discharged by chimney; As close fire door, and stop oxygen supply, can reach the purpose of banking up a fire.During heating, open fire door, and close bell, water temperature can raise rapidly in the heat exchanger.During culinary art, only need open bell and get final product.

The utility model has the advantages that heat exchanger is arranged in the flue, the high-temperature flue gas heat exchange is abundant in water in the heat exchanger tube and the flue; Heat exchanger tube is to tilt 45 degree to be arranged, and the hot water of being convenient to expanded by heating is pressed into outlet conduit by the top, and is replenished by the below water return pipeline; Water outlet water temperature height can make heating room temperature raise, and the body of heater ignition temperature is unaffected; Can fully reduce flue temperature, improve heat exchange efficiency.Can realize that honeycomb briquette stove banks up a fire, be used for culinary art, heating simultaneously.Be applicable to the honeycomb briquette stove of domestic heating.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is a honeycomb briquette heating stove organigram;

Fig. 2 is arranged on the heat exchanger construction figure at flue place.

As seen from the figure, honeycomb briquette heating stove of the present utility model, by body of heater, the combustion chamber, chimney is formed, in body of heater 1 heat-insulation layer 2, be provided with vertical secondary oxygen supply air channel 3 around combustion chamber 5, it is characterized in that, in flue heat-insulation layer 6, be provided with heat exchanger 7, heat exchanger forms the chimney flue type water jacket by shell 4 and inner bag 8, on, under form 45 the degree inclined-planes, shell water jacket at the most significant end of upper inclined surface is connected with outlet conduit 11, in the formed flue of inner bag, be provided with staggered being arranged in parallel, the inclination miter angle, the heat exchanger tube 9 that connects, the heat exchanger tube two ends are connected with wall of inner container, communicate with the water jacket 10 of shell, be connected with water return pipeline 12 at the shell water jacket of the least significant end of chimney flue type water jacket lower bevel.

Claims (2)

1, a kind of honeycomb briquette heating stove, by body of heater, combustion chamber, chimney are formed, in insulating layer of furnace body, be provided with vertical secondary oxygen supply air channel around the combustion chamber, it is characterized in that be provided with heat exchanger in the flue heat-insulation layer, heat exchanger forms the chimney flue type water jacket by shell and inner bag, the upper and lower formation of chimney flue type water jacket 45 degree inclined-planes are connected with outlet conduit at the shell water jacket of the most significant end of upper inclined surface; In the formed flue of inner bag, be provided with the heat exchanger tube of staggered be arranged in parallel, tilt miter angle, perforation, the heat exchanger tube two ends are connected with wall of inner container, communicate with the shell water jacket; Shell water jacket in the least significant end of chimney flue type water jacket lower bevel is connected with water return pipeline.
