Alternatively, described flue be opened in described every coping or bottom.

Alternatively, when n >=3, first described combustor is arranged on the lower section of other described combustor, other described combustions Burn room to be arranged side by side.

Alternatively, n=4.

Alternatively, also include being arranged on the dust collect plant below described combustor.

Alternatively, described dust collect plant includes dust hopper, controller and the valve being arranged on dust hopper, described controller Gleanings in described dust hopper are discharged by the switch controlling described valve.

Alternatively, described dust collect plant is arranged on (n-1)th described combustor and described in n-th between combustor.

Alternatively, described dust collect plant is arranged on combustor described in n-th.

Alternatively, described fire grate is provided with air compartment, and described air compartment provides oxygen for described stoker surface.

Alternatively, air-supply arrangement is set above described feeding mouth, described air-supply arrangement provides oxygen for described burner hearth, and institute Stating air-supply arrangement and providing the wind speed of oxygen is higher than the wind speed that described air compartment provides oxygen.

The application significantly reduce exhanst gas outlet discharge flue gas in flying dust content, improve boiler safety and Efficiency of combustion.

In order to be able to be further understood that feature and the technology contents of the application, refer to detailed below in connection with the application Illustrate and accompanying drawing, but accompanying drawing only provides and uses with reference to explanation, is not used for the application is any limitation as.

Brief description

The aforementioned and other side of the application more completely will be managed by being discussed in detail of being done with reference to the accompanying drawings Solution and understanding, in the accompanying drawings:

Fig. 1 shows a kind of schematic diagram of embodiment of the application；

Fig. 2 shows the schematic diagram of the application second embodiment.

Specific embodiment

For help those skilled in the art definitely understand this application claims theme, below in conjunction with the accompanying drawings in detail The specific embodiment of description the application.

The schematic diagram of one embodiment of the application as shown in Figure 1.A kind of fuel boiler, including burner hearth 10, is arranged on stove The fire grate 20 of thorax 10 bottom, feeding mouth 30 from fuel to burner hearth 10 and exhanst gas outlet 40 for throwing in, wherein, inside burner hearth 10 Several combustor 11 are separated out by partition wall 50, in this embodiment, the quantity of combustor 11 is 4, other real Apply in mode, the quantity of combustor 11 can change according to the actual requirements, as long as being no less than 2.As illustrated, feeding mouth 30 are connected with first combustor 11, and exhanst gas outlet 40 is connected with the 4th combustor 11, passes through between adjacent combustor 11 It is opened in flue 51 sequential communication on partition wall 50.Wherein, the feeding mouth 30 that is connected with same combustor, each flue 51 And/or exhanst gas outlet 40 all opens up and goes up at various height.For example shown in Fig. 1, flue 51 position that combustor 11 connects is each Different.Thus, burner hearth 10 has been partitioned into 4 combustor being sequentially connected 11.Additionally, in this embodiment, first Combustor 11 is arranged on the lower section of other combustor 11, and other three combustor 11 are arranged side by side.This design makes burner hearth 10 Internal structure is compact.It is understood that the arrangement of combustor 11 is not limited thereto, as long as beneficial to flue gas in burner hearth Interior turn to.

With reference to shown in Fig. 1, fuel is put into after burner hearth by feeding mouth 30, and the flue gas producing in first combustor is by flue 51 sequentially pass through each combustor, finally discharge from the exhanst gas outlet 40 of the 4th combustor.In this process, due to each cigarette Road 51 opens up to be gone up at various height, and the flue gas carrying flying dust needs repeatedly to turn to, due to flying dust and flue gas in flow process Density different, there is inertial separation both during steering, most of flying dust can drop in burner hearth 10, rather than with flue gas by Exhanst gas outlet 40 is discharged.As illustrated, as preferably embodiment, flue 51 is opened in top or the bottom of partition wall 50, makes Must carry the flue gas of flying dust 10 in burner hearth in steering angle as far as possible big, thus improving the separation efficiency of flying dust and flue gas.

As shown in figure 1, in this embodiment, also include being arranged on the dust collect plant of described combustor 11 lower section 60, dust collect plant 60 is used for collecting the flying dust of whereabouts.Include dust hopper 61, control as preferably embodiment dust collect plant 60 Device 62 and the valve 63 being arranged on dust hopper 61, the gleanings in dust hopper 61 are arranged by the switch of controller 62 control valve 63 Go out.In this embodiment, controller 62 is, for example, a joystick, and the gleanings in dust hopper 61 can be expelled to stove The slag-drip opening 80 of row 20.As illustrated, as preferably embodiment, dust collect plant 60 can be arranged on latter two combustor Between, or it is indoor to be arranged on last burning.It is understood that the type of dust collect plant 60, position, size And the type of controller 62, position be not limited to above-mentioned.

As shown in Fig. 2 the schematic diagram of second embodiment for the application.In this embodiment, with embodiment One identical place repeats no more.In the present embodiment, fire grate 20 is provided with some air compartments 21, and these air compartments 21 are described stove Arranging 20 surfaces provides oxygen, to help full combustion of fuel.As preferably embodiment, it is also equipped with sending above feeding mouth 30 Wind apparatus 70, this air-supply arrangement 70 provides comburant oxygen into burner hearth 10, and air-supply arrangement 70 provides the wind speed of oxygen higher than wind Room 21 provides the wind speed of oxygen, on the one hand, fully burning can reduce the generation of flying dust, on the other hand, high speed to fuel in the air Air-flow also can help flue gas more swimmingly to arrive at exhanst gas outlet 40 along default path via after the steering of each combustor 11.

It will be appreciated by persons skilled in the art that when a steam generator system employs foregoing fuel boiler, It is capable of aforementioned advantages.

Although the application has been shown and described based on specific embodiment, the application is not restricted to shown thin Section.On the contrary, in the range of claim and its equivalent, the various details of the application can be modified.
