Abstract
The utility model relates to a convective-radiant heating furnace which can improve the coal-burning utilization ratio and effectively reduce the coal of specific energy consumption . The heating furnace adopts an inner and outer layer sleeve structure, the inner layer sleeve adopts a circular pipe arranged vertically, and the outer layer sleeve adopts the heating furnace outer wall which is formed by a plurality of outer layer faceplates. A heat exchange chamber is a space which is formed by the inner layer sleeve, a plurality of outer layer faceplates, a baffle plate, and a supporting plate at the bottom part. A gap is arranged between the baffle plate and the outer layer faceplates, and the heat exchange chamber and the furnace chamber heat preservation chamber are communicated through the gap. When the coal is normally combusted in the furnace chamber, the inner layer sleeve is heated to the certain temperature, and the air in the heat exchange chamber absorbs the certain heat through a convection and radiation way, and forms the hot air, and the hot air is delivered to the room which is required to heat from the air outlet pipe; simultaneously the inner layer sleeve transfers the heat to the outer layer faceplate through a high temperature radiation way, the outer layer faceplate releases the heat to the external space through the air convection and heat exchange, and the radiation ways, and therefore, the heating effect in the room is achieved.
Description
Affiliated technical field
The utility model relates to a kind of heating plant that is used for family's winter heating, especially utilizes the coal-fired convection current-radiant heating stove of natural convection air and high temp objects radiation heat transfer.
Background technology
At present, adopt mostly with water the northern China rural area is the coal heating stove of medium, it is mainly constructed is coal furnace, hot-water line, radiator, return pipe and attached pipe fitting, WATER AS FLOW MEDIUM is heated in coal heating stove, naturally flow to radiator, discharge certain heat, flow back to coal heating stove through return pipe at the radiator place, form the Natural Circulation of water, reach the purpose of room heating.But because above-mentioned coal heating stove adopts the natural circulation mode of water, the hot water of coal heating stove is exerted oneself on the low side, causes unit heating area energy consumption higher.When people go out for a long time, need bleed off WATER AS FLOW MEDIUM, in case bursting by freezing pipeline, radiator etc. make troubles for people's life.
Summary of the invention
Low in order effectively to overcome a large amount of thermals efficiency that exist of existing coal heating stove, the higher and inconvenience of specific energy consumption.The utility model provides a kind of coal-fired convection current-radiant heating stove, and this fire coal convection current-radiant heating stove not only can improve the coal-fired thermal efficiency, and easy for installation, reduces use cost.
The technical scheme that its technical problem that solves the utility model adopts is: this heating stove is inside and outside layer tube-in-tube structure, and inner layer sleeve is the vertical pipe that is provided with, and outer layer sleeve is the heating stove outer wall that is surrounded by the outer panel of several piece.Being provided with the different slab structure of several piece in heating stove inside with the axial vertical direction of inner layer sleeve, is respectively bottom support plate, dividing plate, several piece air baffle, top seal plate from bottom to up.Wherein, the space that is surrounded by inner layer sleeve, the outer panel of several piece, dividing plate and top seal plate is a heat-exchanging chamber, and the space that is surrounded by inner layer sleeve, the outer panel of several piece, dividing plate and bottom support plate is the burner hearth moist closet.Be provided with the slit between dividing plate and the outer panel, be connected by this slit between heat-exchanging chamber and the burner hearth moist closet.Inner layer sleeve is provided with flame retardant coating, and it is burner hearth that flame retardant coating surrounds a space.Be provided with smoke exhaust pipe at the inner layer sleeve upper position, be provided with SD in the smoke exhaust pipe.Deck panels is provided with blast pipe, discharge pipe outside.When fire coal in burner hearth during normal combustion, inner layer sleeve is heated to certain temperature, air in heat-exchanging chamber by convection current, radiation mode, absorb certain heat, form hot blast and be transported to the room that needs heating from discharge pipe: simultaneously, inner layer sleeve is by the hyperthermia radiation mode, heat is delivered to outer panel, outer panel to the space outerpace release heat, reaches the effect of room heating by the heat convection and the radiation mode of air thus.
The beneficial effects of the utility model are, have made full use of convection current, the radiation heat transfer of high temp objects, need the room temperature rising speed of heating fast, the heat exchange efficiency height, and the unit are energy consumption is low.Simultaneously, structure is very simple.

The specific embodiment
In Fig. 1, this heating stove is inside and outside layer tube-in-tube structure, and inner layer sleeve (5) is the vertical pipe that is provided with, and outer layer sleeve is the heating stove outer wall that is surrounded by the outer panel of several piece (8).As shown in figures 1 and 3, being provided with the different slab structure of several piece with the axial vertical direction of inner layer sleeve (5), is respectively bottom support plate (3), dividing plate (16), several piece air baffle (14), top seal plate (10) from bottom to up.
As depicted in figs. 1 and 2, the space that is surrounded by inner layer sleeve (5), the outer panel (8) of several piece, dividing plate (16) and top seal plate (10) is heat-exchanging chamber (15).Deck panels (8) is provided with blast pipe (7), discharge pipe (9) outside.Heat-exchanging chamber (15) communicates with outside atmosphere by blast pipe (7), discharge pipe (9).When the blower fan forced-air blast, air is blown into heat-exchanging chamber (15) from blast pipe (7), air flows along air baffle (14) in heat-exchanging chamber (15), the inner layer sleeve (5) of several transversal flow high temperature, mode by convection current and radiation, heat is delivered to air, and air is blown from discharge pipe (9), is transported to the room that needs heating.When not adopting the blower fan forced-air blast, air in the heat-exchanging chamber (15) is by the radiation heating of the inner layer sleeve of high temperature (5) by convection current, radiation, heated air flows out naturally along discharge pipe (9), because heat-exchanging chamber (15) internal pressure reduces, suck certain air by blast pipe (7) from outside atmosphere, the air that is inhaled into is heated again, flows out again, so, form flowing naturally of air.
As shown in Figure 1 and Figure 4, by inner layer sleeve (5), the outer panel (8) of several piece, the space that dividing plate (16) and bottom support plate (3) surround is burner hearth moist closet (17).Be provided with the slit between dividing plate (16) and the outer panel (8), be connected by this slit between heat-exchanging chamber (15) and the burner hearth moist closet (17), avoid occurring in the burner hearth moist closet (17) phenomenon of hypertonia.
As shown in Figure 1, be provided with flame retardant coating (4) in the inner layer sleeve (5), the space that flame retardant coating (4) surrounds is burner hearth (2), inner layer sleeve (5) bottom is provided with fire grate (1), top is provided with bell (11), upper side is provided with smoke exhaust pipe (12), is provided with SD (13) in smoke exhaust pipe (12).A side lower part of deck panels (8) is provided with ash hole (18) outside.Air flows into burner hearth (2) from ash hole (18), burner hearth (2) in and fired coal combustion, forms flue gas, from smoke exhaust pipe (12) eliminating heating stove.
As Fig. 1, Fig. 2 and shown in Figure 4, coal-fired in burner hearth (2) internal combustion, discharge heat, make inner layer sleeve (5) become high temp objects, form the hyperthermia radiation source, by the space in heat-exchanging chamber (15) and the burner hearth moist closet (17), with the outer panel (8) of heat transferred, the outer panel (8) that absorbs certain heat needs heat transferred by the mode of convection current and radiation the space outerpace of heating.
