Description

A kind of civil multifunctional stove and accessory

Technical field

The utility model relates to a kind of coal stove, and particularly a kind of coal stove that can be used for family, restaurant and the cooking of enterprise and institution dining room, heating, shower and heat supply water belongs to the people (family) and uses the coal stove technical field.

Background technology

At present, the people (family) that have heating or heat supply water use coal stove, and the upper end of its water tank or water jacket all is lower than the lower end of combustion zone, and the water in water tank or the water jacket heats up by the inwall heat absorption adjacent with burner hearth.Its weak point: the one, the part heat in the combustion zone is directly taken away by chimney, and is not used effectively, and the thermal efficiency is reduced; The 2nd, the combustion zone is not provided with enough water jackets, and moisture storage capacity is reduced; The 3rd, can only be from the local heat absorption of the inwall adjacent with burner hearth, heating surface area is little, and the local temperature height shortens its service life; The 4th, there is the drawback that can not make heating and shower, heat supply water take into account use simultaneously because of the thermal efficiency is low.

Summary of the invention

The purpose of this utility model is exactly to provide a kind of to make full use of that heat, heating surface area in the combustion zone is big, the thermal efficiency is high and the civil multifunctional stove and accessory of long service life at above-mentioned weak point.

Technical solution of the present utility model is: a kind of civil multifunctional stove and accessory, comprise body of heater, burner hearth, water jacket, chimney and fire door around burner hearth, it is characterized in that: in the water jacket arranged outside that is in the combustion zone flue circle is arranged, and in this regional water jacket, be provided with the fire tube that connects combustion zone and flue circle.

Fire tube described in the utility model technical solution can be 3 to 12.

Fire tube described in the utility model technical solution can be layer stereo and distribute, and its corresponding each flue circle is flue circle independently, and coupled in series.

The utility model is owing to adopted unique fire tube and two backhaul (many backhauls) composition form, thereby heating surface area is increased greatly, strengthened heat exchange, have the characteristics of sufficient combustion, thermal efficiency height, energy-conservation and multi-use, be fit to family, restaurant and the cooking simultaneously of enterprises and institutions dining room, heating, shower and heat supply water and use.

1, heating surface area is big: heating surface area is comparatively advanced more than three times of selling in the market of heating stove, thereby has strengthened heat exchange, has utilized the waste heat of stove and accessory combustion zone fully, and heat-energy losses is reduced widely.

2, the water jacket inside and outside is heated simultaneously: flue gas passes from fire tube, flows along the water-jacket outer wall in the flue circle, and the water jacket inside and outside is heated simultaneously, has reduced heat loss.When the water temperature in the water jacket was low, the outer wall of chimney was not warm, and only after water temperature raise, the temperature of chimney just can raise, and has illustrated that heat exchange is abundant.

3, water temperature quick heating: because many fire tubes pass from water jacket, heating surface area is increased, and the temperature of flue gas is higher, the water jacket inside and outside is heated, thereby the water temperature in the water jacket rises very fast.

4, energy-conservation, the thermal efficiency is high: the thermal efficiency can reach about 90%, and fuel consumption is few, compares with existing radiator, can fuel saving more than 30%.

5, moisture storage capacity is many: owing to also be provided with water jacket in the combustion zone, thereby the moisture storage capacity of water jacket is increased.

6, long service life: because heating surface area is big, can not cause local temperature higher, thereby prolonged its service life.

7, multi-use: because heating surface area is bigger, improved the thermal efficiency, enough hot water can be provided, thereby can in normal cooking, also can be used for heating, shower and heat supply water, made it really become multi-use.In the market stove and accessory heating and shower, the heat supply water drawback that can not take into account use have simultaneously been solved.

The specific embodiment

As shown in Figure 1 and Figure 2.Body of heater, burner hearth, fire door 7 and chimney 3 are identical with existing Heating stove.Water jacket 5 is around burner hearth, and its upper end is concordant with the upper end of combustion zone.Water jacket 5 is provided with water inlet pipe 6, outlet pipe 4.Water jacket 5 is made by metal material.Water jacket 5 outsides corresponding with the combustion zone are provided with the flue circle 2 of sealing, and flue circle 2 connects with chimney 3.Fire tube 1 is 4, is the fan-shaped even distribution of individual layer, passes water jacket 5, and combustion zone and flue circle 2 are connected.Like this, the water jacket 5 inside and outside walls and fire tube 1 inwall of combustion zone correspondence are heating surface, and heating surface area is increased greatly, and the heat energy of combustion zone is fully used.The radical of fire tube 1 can be decided according to the heating demand, can be 3 to 12, also can be more than 12, also can be layer stereo and distribute, its corresponding flue circle is flue circle independently, and coupled in series, form many backhauls, so that it reaches the desired heating surface area of design.When being double-deck fire tube, lower floor's fire tube is arranged near on the covering of the fan of chimney one end, and lower floor's flue circle and upper strata flue circle are in the position coupled in series away from chimney.

Claims (3)

1, a kind of civil multifunctional stove and accessory, comprise body of heater, burner hearth, water jacket (5), chimney (3) and fire door (7) around burner hearth, it is characterized in that: flue circle (2) is arranged being in the water jacket of combustion zone (5) arranged outside, and in this regional water jacket (5), be provided with the fire tube (1) that connects combustion zone and flue circle (2).

2, a kind of civil multifunctional stove and accessory according to claim 1 is characterized in that: described fire tube (1) is 3 to 12.

3, a kind of civil multifunctional stove and accessory according to claim 1 and 2 is characterized in that: described fire tube (1) is layer stereo and distributes, and its corresponding each flue circle (2) is flue circle independently, and coupled in series.
