Description

The energy-efficient civil heating stove of three backhauls

It is the civilian hot-water heating heating stove of fuel with the honeycomb briquette that the utility model relates to a kind of, the energy-efficient civil heating stove of especially a kind of three backhauls.

Present domestic civil heating stove has three kinds of basic structure forms: 1, single backhaul heating stove, its structure as shown in Figure 1, the flame of this stove and accessory fire coal and high-temperature flue gas directly enter the chimney emptying through burner hearth upwards mobile (backhaul), the heat that coal combustion produces is directly passed to water jacket by tile, and coal-fired thermal-flame fails to contact with water jacket, and the heat of high-temperature flue gas is not fully utilized yet.2, single backhaul-flue water sleeve type heating stove, its structure as shown in Figure 2, this structure is that attempt makes full use of heat in the flue gas, because the length of flue water jacket is generally all less than 0.5 meter, the time of staying less than of flue gas in water jacket 0.4 second is so exchange heat is insufficient.3, single backhaul-fire suppressed type heating stove, this kind of stove and accessory are to add the heat transfer wing on the water jacket inwall above the tile, and cover fire-suppressing cover (as shown in Figure 3) above wing, and its heat energy utilization rate has had raising to a certain degree.Above-mentioned three kinds of stove and accessorys all exist the heat energy utilization rate low, and no overfire air device wastes energy, and can not heat up water to cook and change weak points such as watt inconvenience.

The purpose of this utility model is for a kind of heat energy interest rate height is provided, and can heat up water to cook and change the energy-efficient civil heating stove of three backhauls watt easily.

The utility model is by bell 4, fairing cap 5, oxygen supply ring 6, tile 7, water jacket 9, shell 11, heat-insulation layer 12, fixed tile 13, secondary air channel 14 is formed, the lower side that it is characterized in that water jacket 9 has a vent openings 16 and a water inlet, one delivery port is arranged at top, there is certain clearance the inboard of the outside of water jacket 9 and shell 11, form inner flue 10 by this gap, the bottom outlet flue of the suitable for reading and chimney of inner flue 10 communicates, establish wind shelves 3 at the throat place, between the water jacket 9 of throat opposite side and shell 11, be provided with heat-insulation layer 12, the inner face of water jacket 9 and fixed tile 13 have certain clearance, form passage 15 by this gap, tile 7 is fixed on by fixed tile 13 and forms burner hearth in the stove, be provided with oxygen supply ring 6 in the upper end of tile 7, at secondary air channel 14 of a side of passage 15 welding, the upper end of secondary air channel 14 is near oxygen supply ring 6, stone or metal plate for standing a stove on as a precaution against fire 2 is contained in the upper end of water jacket 9, place, bottom centre hole at stone or metal plate for standing a stove on as a precaution against fire is provided with a fairing cap 5, top is provided with bell 4, there is the outlet flue of a band deep bead 1 side of stone or metal plate for standing a stove on as a precaution against fire, the downside of portion welds an annular plate in the enclosure, welding fire grate below the internal circle of annular plate, below fire grate, be provided with ash output box, below the side of shell, leave the ash output box mouth.

Further specify below in conjunction with the architectural feature of accompanying drawing utility model.

Figure 10 is that A, the B of Fig. 9 is to view.

Figure 11 is the structural representation of fixed tile 13.

Fairing cap 5 among Fig. 5 is made up of circular bottom plate and water conservancy diversion lobe, and the water conservancy diversion lobe becomes M shape.Fairing cap 5 main rising are suppressed fire and guide functions, and with flame and flue gas uniform distribution and guide channel, following current is downward, confluxes to the lower side vent openings of water jacket 9 again by its water conservancy diversion lobe.

Oxygen supply ring 6 among Fig. 7 has passage for the convexity of band center hole in the side of dome.Form overfire air device by oxygen supply ring 6 and secondary air channel shown in Figure 9, the burning that can be the fuel gas that volatilizees in the coal provides sufficient air (oxygen), to improve the heat energy utilization rate.

Fixed tile 13 shown in Figure 11 is that a slice has certain flexible rectangle thin type, is assemblied in to be tubular in the stove and accessory.Main fixedly tile 7 and sealing and the heat transfer effect of rising.

In use with the lower water inlet of water jacket 9 and the delivery port on top, be connected with feed pipe with the return pipe of heating system respectively, light the honeycomb briquette 8 in the burner hearth, as shown in Figure 4, the following current in stove of flame that coal combustion produces and high-temperature flue gas is upwards flowed, finish first backhaul, heat coal-fired and high-temperature flue gas is given tile by radiation and conduction, pass to passage 15 by tile 7 again, pass to water jacket 9 through convection current, behind flame and the high-temperature flue gas rising bump fairing cap 5, diversed beneficial 5 distribute naturally, evenly be folded to 9 passages 15 of tile 7 and water jacket, under the natural draft effect of chimney, following current flows downward, and finishes second backhaul and also entrained heat convection current is conducted to water jacket 9, conflux to opening 16 places of water jacket 9 bottoms then, enter inner flue 10 by opening 16, following current upwards enters chimney again, finishes the 3rd backhaul, in this backhaul, the heat in the flue gas further passes to water jacket 9.The exchange heat of three backhaul stove and accessorys is divided and is carried out for three times, the heating surface area of stove and accessory is big, flue gas is long flow path in stove, the area of section of annular channel is big, flue gas flow rate is slow, make that exchange heat is very abundant, contained heat seldom (non-scald on hand) in the flue gas of emptying, like this, guarantee that coal-fired heat energy utilization rate is improved to greatest extent, add that secondary wind action fuel gas can fully burn, greatly reduce the heat loss of chemically incomplete combustion, therefore, the thermal efficiency of other similar stove and accessorys of thermal efficiency ratio of this stove and accessory has had and has increased substantially.

The utility model is three backhaul forms, and thermal efficiency height is economized on coal, good heating effect, and in addition, because tile 7 (being coal) is near apart from stone or metal plate for standing a stove on as a precaution against fire 2, flame is by last, take pot after, flame can burn to the bottom of a pan, the effect of cooking of therefore heating up water is fairly good.It is simple in structure, change watt and deashing all very convenient.
