Abstract
The utility model provides a furnace door structure of a powder burner, comprising a primary air pipe, an observation sight glass, an ignition port and a secondary air pipe. The secondary air pipe surrounds the primary air pipe in a whirl manner and is opened on the hearth. Furthermore, a plurality of blades extending in the hearth are arranged in the secondary air pipe; the opening of the secondary air pipe is parallel and/or vertical to the axial line of the furnace. The secondary air enters into the hearth through the secondary air pipe in a multi-path manner and enters into the hearth spirally along the direction which is parallel and/or vertical to the axial line of the hearth under the action of the blades in the air pipe to participate the burning. The furnace door structure has simple structure; the powdered coal and the air are mixed fully because of spiral entering of the secondary air so that the burning is full and the heat utilization rate is high.
Description
Technical field
The utility model relates to technical field of heating, specifically is meant a kind of dust-firing heat-obtaining equipment.
Background technology
Rise along with oil price, the dust-firing machine progressively replaces Oil fuel combustion stove, existing dust-firing stove and accessory has blower fan, outer cylinder body, inner barrel, burner hearth bonnet, coal chute, oil gun etc., after the wind of blower fan blasts outer cylinder body, a part enters in inner barrel and the burner hearth through the inboard air intake of bonnet, and it is in the burner hearth that another part wind enters inner barrel by cavity secondary air between outer cylinder body and the inner barrel.
In the existing door structure, primary air nozzle is arranged on the fire door, generally carries coal dust secretly by a wind and enters burner hearth via primary air nozzle; Fire door also is provided with oil gun and lighting-up tuyere, in order to firing coal-dust; Overfiren air port is located on the body of heater, and secondary wind enters the cavity between the inside and outside cylindrical shell, enters burner hearth via the air inlet tangent line of inner barrel.
The separately design of primary air nozzle, overfiren air port causes overall structure too fat to move; The design of the design of inside and outside cylindrical shell, fire door and body of heater welding all causes the combustor dismounting loaded down with trivial details, inconvenient maintenance.Problems such as simultaneously, it is insufficient also to exist dust-firing, and the thermal efficiency is lower.
The utility model content
The technical problems to be solved in the utility model is the defective that overcomes existing dust-firing machine fire door, provide a kind of topology layout rationally, easy accessibility, door structure that the coal dust utilization ratio is high.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The door structure of dust-firing machine which is provided with airduct, observation visor and lighting-up tuyere one time, also is provided with secondary air channel, and described secondary air channel is vortex shape around an airduct, and is opened on burner hearth.Further, establish many blades that extend the burner hearth direction in the described secondary air channel, the opening of secondary air channel is parallel and/or perpendicular to the body of heater axis.
Fuel is carried secretly by a wind of an airduct and is entered in the combustor, and the oil burner high temperature that is set at lighting-up tuyere is lighted, and heat is emitted in burning.Secondary wind enters in the burner hearth by secondary air channel branch multichannel, and can be under the effect of airduct intra vane parallel or enter burner hearth perpendicular to burner hearth axis spiral, and participates in burning.The structure of this design is simple and direct, and is easy for operation, and secondary wind multichannel spiral enters and more guaranteed fully mixing of coal dust and air, makes burning more abundant, and heat utilization efficiency is higher.
Simultaneously, the matrix of described door structure is flange form, and heat-insulation layer is established in the inboard of door structure.The flange form setting can make things convenient for it to be connected easy accessibility with body of heater; Heat-insulation layer in the fire door can reduce the loss of heat, improves the efficient of combustor.

Fig. 5 is the fire door perspective view 2 of the dust-firing machine of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, a kind of dust-firing machine comprises fire door 1, body of heater 2, slag-tapping system 3 and shower nozzle 4; Fire door 1, shower nozzle 4 are located at the front and back end of body of heater 2 straight tubes respectively; Slag-tapping system 3 is located at the bottom of body of heater 2; Fire door 1, slag-tapping system 3 and shower nozzle 4 are that flange form is connected with body of heater 2.Adopt flange to connect between each parts, can dismantle apace, make its installation and maintenance more convenient.
As Fig. 2-shown in Figure 5, door structure which is provided with airduct 11, a secondary air channel 12, observes visor 13 and lighting-up tuyere 14, and secondary air channel 12 is vortex shape around an airduct 11, and is opened on the burner hearth of body of heater 2; Establish many blades 15 that extend the burner hearth direction in the secondary air channel 12, the opening of secondary air channel 12 is parallel and/or perpendicular to the body of heater axis.
Fuel is carried secretly by a wind of an airduct 11 and is entered in the combustor, and the oil burner high temperature that is set at lighting-up tuyere 14 is lighted, and heat is emitted in burning.Secondary wind enters in the body of heater 2 by 12 fens multichannels of secondary air channel, and can be under the effect of airduct intra vane 15 parallel or enter burner hearth perpendicular to burner hearth axis spiral, and participates in burning.
Heat-insulation layer 16 is established in the inboard of door structure, can reduce the loss of heat, improves the efficient of combustor.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
