The utility model discloses a coal furnace with high thermal efficiency, which comprises a faceplate, a base, an outer furnace casing, a core of furnace and a check bridge; wherein the interior of the outer furnace casing is provided with an oxygen supply barrel and the external wall of the outer furnace casing is connected with a main flue and an auxiliary flue, the main flue with a fire damper inside is communicated with a main exhaust port, the core of furnace is positioned at the top of the oxygen supply barrel, the base is provided with an ash box inside, and the outer furnace casing and the base is connected with a ring-like flue, which is communicated with the outer furnace casing and is provided with an outlet flue communicating with the main exhaust port via the auxiliary flue. Compared with the prior art, the utility model has the advantages of better heating effect, is not easy to be blocked and is convenient and energy-saving in usage.
Description
Technical field: the utility model relates to a kind of coal furnace, and especially a kind of high heat is imitated coal furnace.
Background technology: (number of patent application is patent: 200420060293.4) to disclose a kind of " base air return type coal furnace " in the prior art, it is by outer furnace barrel, combustion chamber, Air return ring, the combustion chamber supporting seat, the travelling oven axle assembly, the base assembly, thermal insulation board, flue and the flue conversion air door that is arranged in the flue constitute, on the end face of base assembly, be provided with base return air hole and base return air general export, when warming oneself winter, after closing flue conversion air door, the hot flue gas that burning produces flows and passes through from base return air hole and base to the body of heater bottom, discharge by total outlet flue through flue from base return air general export again, by flowing of hot flue gas with outer furnace barrel, the base assembly, the roasting heat of flue, thus reach the purpose that strengthens heating effect.But this coal furnace impurity that easily contained in the flue gas of base return air hole in use stops up, and influences result of use; And owing in base, be provided with ash bin, be easy in the time of in hot flue gas is flowed through base the ash in the ash bin is entrained in the flue gas in a large number, and in auxillary flue and smoke exhaust pipe, deposit, cause auxillary flue and smoke exhaust pipe blocked; In addition,, when flue gas is flowed through base, can contact, make the heat loss of flue gas bigger, greatly reduce the utilization rate of heat, influence heating effect with cold air on every side because base communicates with atmosphere.
Summary of the invention: the purpose of this utility model is: provide that a kind of heat loss is little, heating effect good, be difficult for stopping up, high heat easy to use is imitated coal furnace, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: high heat is imitated coal furnace, it comprises panel (1), base (2), outer furnace barrel (3), combustion chamber (4) and grate (5), in outer furnace barrel (3), be provided with oxygen supply bucket (6), on the outer wall of outer furnace barrel (3), be connected with flue collector (10) and auxillary flue (11), flue collector (10) communicates with total exhaust opening (13), in flue collector (10), be provided with fire banking-up board (12), combustion chamber (4) is contained in the top of oxygen supply bucket (6), in base (2), be provided with ash bin (16), on outer furnace barrel (3) and base (2), be connected with annular flue (7), annular flue (7) communicates with outer furnace barrel (3), be provided with outlet flue (9) on annular flue (7), outlet flue (9) is communicated with total exhaust opening (13) by auxillary flue (11).
Above-mentioned high heat is imitated coal furnace, and annular flue (7) is connected on the bottom outer wall of outer furnace barrel (3), and communicates with outer furnace barrel (3) by the mouth (8) that advances that is arranged on the outer furnace barrel (3).
Above-mentioned high heat is imitated coal furnace, and the width of annular flue (7) is less than or equal to the width of base (2).
Aforesaid high heat is imitated coal furnace, and annular flue (7) is an annular or square.。
Owing to adopted technique scheme, the utility model is provided with an annular flue on outer furnace barrel and base, and annular flue is connected with outer furnace barrel.When heating, close fire banking-up board, the hot flue gas that fired coal combustion produces moves to the body of heater bottom after combustion chamber comes out, and the mouth that advances on outer furnace barrel enters into annular flue, around one week of annular flue motion after the outlet flue of annular flue enter into auxillary flue and discharge by total exhaust opening, can prolong the time of staying of hot flue gas in body of heater like this, just discharge body of heater after making flue gas in body of heater, pass through mobile fully and circulation, made full use of the heat of flue gas, to improve the thermal efficiency, to reduce thermal loss, reach purpose of energy saving.Compare with " the base air return type coal furnace " of prior art, the utility model is passed through hot flue gas by annular flue, enters into annular flue because flue gas is the mouth that advances through being arranged on the outer furnace barrel, and advances mouth and is difficult for stopping up.And, auxillary flue and smoke exhaust pipe can not stopped up because of a large amount of depositions of coal ash because the flue gas ash bin of not flowing through can not carried a large amount of coal ash secretly in the flue gas.In addition, because annular flue and atmospheric isolation, flue gas does not contact with cold air when flowing through annular flue, and the thermal loss of flue gas is little, the heat utilization ratio height; And heating the time can directly be placed on pin on the annular flue, and sensation can be warmer; Because annular flue is arranged on the outer wall bottom of outer furnace barrel, the flue gas of flowing through is in the roasting warm with annular flue, and heat upwards distributes, and is equivalent to simultaneously to make the temperature of outer bucket higher to the inner and outer wall heating of outer furnace barrel, and heating effect is better.Therefore, compared with prior art, the utlity model has the better and difficult obstruction of heating effect, easy to use, energy-saving advantages.
