A water jacket of a flue pipe is provided with a water outlet, the upper part of the furnace body and the centre of the flue pipe are provided with a rake-shaped hollow heat collecting pipe, wherein, one head of which is connected with the water preheating interlayer, and the other head is connected with the water jacket of the flue pipe. The utility model has the advantages of high thermal efficiency, low cost and little energy consumption. The utility model is a furnace suitable for heating and living of wide towns.

Description

A kind of efficient heating household stove

The utility model belongs to a kind of efficient heating household stove.

Present existing coal heating stove, heating efficient is not very high, the exchange of heat energy is carried out in the combustion chamber, the heat that burning produces is adopted heat pipe at any time and is taken away, make the temperature of burner hearth periphery descend fast, the burning of periphery as a result very a little less than, ratio of combustion in the middle of having only is more abundant, but the heat energy of intermediate combustion has only a part seldom to be utilized, the stove that makes can drive radiator, must add the fuel of excess, could satisfy the needs of indoor temperature, Hen Dayibufen heat energy is wasted from flue again at the same time.So there is defective on the structure, and heaviness very, power consumption is high, is not Eco-power heating stove.

The purpose of this utility model is to have designed a kind of heat energy utilization rate height for the weak point that overcomes above-mentioned prior art, and cost is low, the heating household stove of efficient energy-saving.

This use novel purpose be achieved in that this efficient heating household stove it by body of heater, be provided with the water preheat interlayer around the body of heater and between the combustion chamber, chamber wall has flame retardant coating, upper of furnace body is the cutting edge of a knife or a sword burner, the bottom is provided with air inlet and ash bin, body of heater is provided with water inlet, chimney water jacket is provided with delivery port, is provided with a hollow heat pipe of adopting of the rake shape that can intake in the middle of the chimney of upper of furnace body, and his one is connected with the water preheat interlayer, the other end is connected with chimney water jacket, this stove has two chimney water jackets, and one is horizontal, and another erects, the end at the chimney of horizontal stroke is provided with openable gray-drawing port, and the wicket that is provided with stoking on the furnace wall constitutes.Chimney also can be to have only a vertical chimney that has water jacket.

This use is novel to have heat energy utilization rate height, conduct heat fast, cost is low, the advantage of efficient energy-saving.

Fig. 1 is the furnace construction schematic diagram of two chimney water jackets;

Fig. 2 is the furnace construction schematic diagram of a vertical chimney water jacket;

Fig. 3 is a body of heater external structure schematic diagram;

The hollow heat pipe structure schematic diagram of adopting of Fig. 4 rake shape;

Fig. 5 is the heat box structure schematic diagram that rises;

The embodiment given below in conjunction with accompanying drawing is described in further detail the utility model: he is hollow one by one approximate half truncated-cone shape for the water preheat interlayer of this efficient heating household stove 1, the periphery of 2 outsides is done separation layer with flame retardant coating 3 in the combustion chamber, the stove fire with the stove centre does not directly contact, be connected with the hollow heat pipe 9 of adopting of rake shape with the water jacket 10 of chimney above, it is a preheating storage discharge bay; Air outlet 5 is two pipes, and air is directly delivered to the middle part of stove in 2 bottom in the combustion chamber; Rake shape is hollow adopts in the middle of the heat pipe 9 is the water that is used for transferring heat energy, he is placed on the centre of flue, water is adopted Fast Heating in the heat pipe 9 in that rake shape is hollow once more after 1 preheating of preheating interlayer, fully the heat in the chimney is gathered, his one is connected with water preheat interlayer 1, and the other end is connected with chimney water jacket 10; It is horizontal that this stove has 10, one of two chimney water jackets, and another erects; Gray-drawing port 11 is in the end of the chimney of horizontal stroke, and he can open, and with the ash rake collection ash that rake shape is adopted on heat pipe 9 and the chimney wall is cleaned out, and improves and adopts the thermal efficiency; He is divided into two parts with combustion chamber 2 cutting edge of a knife or a sword burner 4, and bore is less relatively, can increase the suction (very prosperous can the cooking of fire of burner hearth like this) of fire; Feeding port 12 is on the furnace wall, and a wicket can be opened stoking; Ash bin 6 can be extracted down ash out in the bottom of stove; Heat rises by storage tank (seeing accompanying drawing 5) on the return pipe of heating installation, is used to become to put because of the heat volume that makes water that rises increase the water that has more.When coal takes fire in combustion chamber 2, directly do not adopt heat from the furnace wall, but in the middle of flue, adopt heat, therefore the temperature in the combustion chamber 2 can be maintained, burning very fully, the heat that burning discharges is just high, rake shape in the middle of the stove chimney is hollow adopt the area of heat pipe 9 relative bigger, and be heated fully all around, simultaneously the water jacket 10 on the chimney wall also is heated, but preheating interlayer 1 inherent flame retardant coating 3 is not adopt heat when not heated, after coming on the temperature of stove, the preheating interlayer also begins water is heated, and prevents that heat energy from passing through the body of heater radiation, because the hollow water jacket of adopting on heat pipe 9 and the chimney wall 10 of rake shape in the middle of the chimney carries out large-area heating, make the chimney and the combustion chamber 2 interior temperature difference increase, it will be very strong having the heat cross-ventilation, like this, and hydro-thermal very fast, the temperature difference of delivery port 8 and water inlet 7 is also very big, the proportion of hot water and cold water differs increasing, and the circulation rate of water is just accelerated, and the thermal power transfer of water just is enhanced.The adopting heat and can be divided into following process of this stove: the water in the preheating interlayer is gathered the heat of flame retardant coating 3 radiation, the hollow water of adopting in the heat pipe 9 of rake shape is gathered once more to heat in the middle of flue, 10 pairs of heat of the water jacket of chimney are gathered again to heat in two sub-sections, through three collections, so the thermal efficiency is very high to heat energy.The water of this stove is open (heat tank 13 that rises is arranged on caliduct, and when the volume of water increased, water flow in the pond, and water flow in the loop body when temperature descended) in addition
