Description
Technical field
The utility model belongs to field of boilers, especially a kind of high-effect moulding coal boiler.
Background technology
The heat that present boiler adopts coal, moulded coal and source of the gas burning to form more heats the cold water in the burner hearth ring wall interlayer, forms heat exchange, thereby the thermal water source is provided.Flue dust is few, blowdown flow rate is little because molded coal boiler has, so it is widely used in the life.But there are following several point defects in existing molded coal boiler: 1. present molded coal boiler is subjected to its structural limitations, can not fully heat the water in the interlayer in conjunction with multiple heat exchange patterns such as radiation, convection current, causes the significant wastage of the energy; 2. boiler is long-term use after, can pile up a large amount of cigarette ashes in its smoke exhaust pipe, cumbersome and be difficult for cleaning out to the smoke exhaust pipe deashing of vertical setting at present, therefore greatly influenced the heat exchange effect of boiler and influenced indoor health; 3. owing to be subjected to the restriction of its volume, can only place several moulded coals in its burner hearth, so burning time be shorter, and need carry out coal continually; 4. if increase the volume that the interior moulded coal quantity of burner hearth will inevitably increase boiler, cause its floor space to strengthen, and increase the manufacturing cost of boiler; In the prior art because the moulded coal in the moulded coal burner hearth is less, heat that its burning the time is produced is also lower, therefore is difficult to guarantee the water in the ring wall interlayer is fully heated.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of volume little, make full use of the high-effect moulding coal boiler that multiple heat exchange pattern reaches good heat exchange effect, can place the polylith moulded coal in the burner hearth of this molded coal boiler in addition, the incendivity time is long.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of high-effect moulding coal boiler, by bell, body of heater, base, burner hearth and the water inlet and the delivery port that are installed on the body of heater constitute, body of heater is installed together with base is coaxial, one ring wall interlayer is arranged between burner hearth in body of heater and the body of heater, water inlet and delivery port are communicated with this ring wall interlayer respectively and are arranged on the following of body of heater, top, the dividing plate that is packed in furnace body inside top makes upper of furnace body form a ring-type flue dust chamber, this ring-type flue dust chamber is connected with chimney on being packed in body of heater, the axial uniform smoke exhaust pipe that can be communicated with burner hearth and flue dust chamber that is fixed with between burner hearth and the dividing plate, it is characterized in that: but upper of furnace body is equipped with the sealing rotating disk in capping flue dust chamber, the bell spiral-lock is in the burner hearth upper end, be shaped on the water jacket samdwich that is connected with delivery port in this bell, but the uniform in the axial direction placing type burning of coal chamber that is shaped on of the combustion chamber of lower furnace portion is equipped with fire grate and removes ash bucket on the base with respect to the combustion chamber lower position.
And, be shaped on an ash removing opening on the described sealing rotating disk.
And a coal flap is put in described combustion chamber upper surface, is shaped on a stoke hole on this coal flap.
Advantage of the present utility model and beneficial effect are:
1. bell spiral-lock of the present utility model is in burner hearth upper end, and is shaped on the water jacket samdwich that is connected with delivery port in this bell.Water in the delivery port flows in the bell, is transported in the heating system after heating once more in bell.This high-effect moulding coal boiler makes full use of the energy, in conjunction with multiple mode of heatings such as radiation, convection current cold water is heated, and has improved significantly to add thermal effect, and has greatly improved the efficiency of heating surface.
2. but uniformly on the combustion chamber in the burner hearth be shaped on a plurality of placed type burning of coals chamber, so can place two, 30 moulded coals simultaneously in the burner hearth.This structure can prolong burning time, reduce to change the frequency of moulded coal, make this boiler convenient in use, save trouble.
3. owing to have a large amount of moulded coals to burn simultaneously in the burner hearth, therefore can produce more heat and carry out abundant heat exchange with cold water in the ring wall interlayer, make cold water heat rapid and guaranteed thermal water source's high water temperature.The heat that this molded coal boiler produced can be fully utilized, and helps the raising of heat exchange efficiency.
4. uniformly between burner hearth and dividing plate be fixed with a plurality of smoke exhaust pipes, this smoke exhaust pipe can increase heat exchange area effectively, improves heat exchange efficiency and guarantees the heat exchange effect.
5. the utility model adopts and make a plurality of combustion chambers and the structure that can place the polylith moulded coal in each combustion chamber on combustion chamber.Can guarantee that the moulded coal in the combustion chamber fully burns, can under the situation that does not increase boiler overall volume and manufacturing cost, in burner hearth, place moulded coal as much as possible again.Increased the range of application of this molded coal boiler, made it suit in medium-sized and small enterprises, to use.
6. the hot gas when the coal flap of combustion chamber upper surface storing can be avoided coal in the combustion chamber is scalded the people, has strengthened the security that this high-effect moulding coal boiler uses.
7. but the utility model is equipped with the sealing rotating disk in capping flue dust chamber in upper of furnace body, and is shaped on an ash removing opening on the sealing rotating disk, goes back capping one rotatable end cap on the ash removing opening.During deashing, only need rotatory sealing rotating disk to smoke exhaust pipe top can carry out deashing, this ash removal method is simple and convenient, efficient is high, effective, can guarantee indoor health, and is free from environmental pollution, can improve the heat exchange effect of boiler again effectively.
The utility model be a kind of reasonable in design, volume is little, deashing is simple and convenient, security performance is high, the high-effect moulding coal boiler that suits to use in medium-sized and small enterprises.It makes full use of the energy, in conjunction with multiple mode of heatings such as radiation, convection current cold water is heated, and has improved the heat exchange effect significantly, and has greatly improved heat exchange efficiency, thereby has guaranteed that the thermal water source has higher temperature.
