A kind of energy-conservation firewood and coal stove
Technical field
The utility model provides a kind of stove and accessory, particularly a kind of firewood and coal stove.
Background technology
Existing is that the stove and accessory of fuel is more with bavin and coal, adopts the directly structure of smoke evacuation of fire door mostly, and this class stove and accessory causes stove one's parents portion and fuel fully not to burn because smoke evacuation is not smooth, and not only smog is big, and heat is imitated not high.The smoke exhaust pipe that also has some firewood and coal stove tools directly to communicate in furnace wall upper lateral part setting and stove one's parents portion, can to a certain degree solve the smog emission problem, but because smoke exhaust pipe directly communicates with the stove hall, smoke evacuation concentrates on a direction, the burning of stove one's parents portion abundant inadequately, energy-saving effect is still undesirable.
Summary of the invention
The purpose of this utility model just is to provide a kind of energy-conservation firewood and coal stove, and its favourable smog emission can make stove one's parents portion full combustion of fuel, and firepower is big, and heat is imitated high, good energy-conserving effect.
For achieving the above object, embodiment of the present utility model is: a kind of energy-conservation firewood and coal stove, it is characterized in that having stove hall, furnace wall, air inlet passage, and stove one's parents side is provided with annular flue, and annular flue communicates with the Lu Tang top, and annular flue is connected to discharge flue.
Between described annular flue and the Lu Tang top annular ring is arranged, there is exhaust opening this annular ring top, and the exhaust opening that discharge flue one side is set is more young than its counterparty's smoke evacuation.
The cross section of described discharge flue is horizontal wide perpendicular narrow square or oval.
Described air intake passage leading portion horizontally set, back segment vertically is provided with.
For ease of placing the less cooker of pressure cooker equal-volume, an also configurable spill packing ring on the furnace roof has fire hole in the middle of this spill packing ring.
The utility model can make smog evenly discharge owing to be provided with the annular row flue, thereby assurance stove hall full combustion of fuel has characteristics such as firepower is big, heat effect height, energy-saving fuel, adapts to the rural area especially, urban household uses.

The specific embodiment
As shown in Figure 1, this energy-conservation firewood and coal stove has stove hall 1, furnace wall 2, grate 3, ash hole 4, air intake passage 5, between stove hall 1 and furnace wall 3, thermal insulation layer 6 is arranged, be provided with annular flue 7 around the fire door on stove hall 1 top, top one side of furnace wall 2 is installed discharge flue 8, discharge flue 8 is connected with annular flue 7, be provided with annular spacer ring 9 between annular flue 7 and stove hall 1 top, annular spacer ring 9 does not contact furnace roof 10, space between itself and the furnace roof 10 constitutes exhaust opening 11, exhaust opening 13 near discharge flue 8 one sides is littler than its counterparty's exhaust opening 12, leading portion 14 horizontally sets of air intake passage 5, back segment 15 vertically is provided with, and helps so more preventing that heat energy from losing from air inlet.Ash hole 4 is arranged at stove hall bottom.
As Fig. 1, shown in Figure 3, place for ease of some small-sized cookers and to use, spill packing ring 16 of movable preparation on the furnace roof 10, these spill packing ring 16 outers 17 can place on the furnace roof 10, have in the middle of the matrix packing ring 16 and the stove hall fire hole through adapting 18 directly.
As shown in Figure 2, for more helping smog emission, discharge flue 8 is wide shape square cylindrical shell.
