Abstract

The utility model provides the technical proposal of an energy-saving firewood burning and coal burning stove. A stove body is an integral member made of refractory materials or coarse porcelain materials; a stove opening is away from one side of a flue outlet relative to the center of a pot (kettle); the upper plane of the stove opening is higher than the bottom of the flue outlet; an outer ring of a stove ring forms an inwards concave type; the upper surface of a stove grate forms a zigzag shape. The stove of the proposal has the advantages of corrosion resistance, quick ignition, strong flame, high heat efficiency, cleanness, convenient carrying, etc.

Description

Energy-saving firewood stove

The utility model relates to agricultural kitchen range technical field.

In vast rural area, family's kitchen range are large stove or little native kitchen range and the common honeycomb briquet stoves based on burning firewood, straw.Large stove and little native kitchen range all exist can't move, dirty, defective that the thermal efficiency is low, large stove also need be combustion-supporting with bellows simultaneously, also there is the waste in the use in populous family; Common honeycomb briquet stove,, very hot oven duration weak point slow owing to lighting slowly, firing, and should be acute poor.

The utility model is exactly the weak point at agricultural kitchen range, and provide that a kind of shaft is corrosion-resistant, stove is lighted soon, hyperactivity of fire, thermal efficiency height, clean, move conveniently, price is low, the combustion bavin that is suitable for batch making, coal-fired new stove and accessory, can make a large amount of agricultural fuel be fully used energy savings.

In order to achieve the above object, this stove and accessory is taked following technical scheme.

Shaft adopts refractory material or coarse porcelain goods, and the fire door center in it is far away than pot (kettle) centre-to-centre spacing outlet flue, and the plane is higher than the outlet flue bottom on the fire door, nearby in outlet flue central horizontal face position; The stove circle of shaft upper end matches complete, and the indent formula is adopted in the outer ring.Plane indentation on the fire grate is supported by three knees, is inclined in the burner hearth along direction on the flue.

Adopt the stove of this programme, connecting chimney can use.Because shaft (3) adopts refractory material or coarse porcelain goods, thereby have non-corrosive, corrosion-resistant, the life-span is long, cost is low characteristics.Because the flame of stove emits to outlet flue by nearest route, thereby on away from the direction of outlet flue pot (kettle) end only can directly be burnt greater than the part of fire door by a spot of flame, and this programme has adopted fire door (II) away from outlet flue (III), and the method for pot (kettle) center (I) invariant position, thereby pot (kettle) end, reduce greater than the part of fire door (II) on away from the direction of outlet flue (III), be the route lengthening of flame in stove, the area that pot (kettle) end is directly burnt strengthens.Like this, this programme is compared with existing kitchen range, and the flame of same temperature, same heat time heating time, the heat that pot (kettle) absorbs is just many, has reached the raising thermal efficiency, fuel-saving purpose.Simultaneously, this programme has adopted indent formula stove circle (4) and fire door (II) to go up the method that the plane is higher than outlet flue (III) bottom, make the distance on the last plane of pot (kettle) end and fire door (II) moderate, make the flame that emits to outlet flue (III) can directly burn pot (kettle) end, further reduced the heat loss.In addition because indentation above the fire grate (1) of this programme has a fixed gap thereby make between fuel and the fire grate (1), and good permeability helps ventilating, make that stove is lighted soon, fuel combustion abundant, hyperactivity of fire.Next is because the kitchen range of this programme are good sealing performance stove and accessory goods, and therefore use is clean, area occupied is little, move convenience.This shows that the utility model is compared with the kitchen range that generally use in present rural area, has superiority preferably, can effectively solve emergency fire problem, making widely, agricultural fuel is fully utilized.Has use value preferably.

Accompanying drawing is the utility model embodiment cutaway view.

The utility model is described in further detail below in conjunction with accompanying drawing.This wood stove shaft (3) is an integrated member, and available refractory material or china clay is prefabricated, fire.On the centerline direction of outlet flue (III), fire door center (II) is than the distance of pot (kettle) center (I) to outlet flue (III).It is complete to place indent formula stove circle (4) and stove circle (5), bell (6) on the shaft (3) to match, and is ironcasting.Indentation above the fire grate (1) is ironcasting, becomes bar (2) support by three cast irons (or steel) and is inclined in the shaft (3).

Claims (1)

1. A kind of energy-saving firewood stove, comprise shaft (3), stove circle (4), (5), bell (6), fire grate (1), knee (2), it is characterized in that shaft adopts refractory material or coarse porcelain goods, fire door center in it is far away than pot (kettle) centre-to-centre spacing outlet flue, the plane is higher than the outlet flue bottom on the fire door, nearby in outlet flue central horizontal face position; The stove circle of shaft upper end matches complete, and the indent formula is adopted in the outer ring; Plane indentation on the fire grate is supported by three knees, is inclined in the burner hearth along the flue direction.
