Description

Double-layer grate back burns atmospheric pressure kiln

Affiliated technical field

It is a kind of novel trans burning boiler with double-layer grate structure that double-layer grate back described in the utility model burns atmospheric pressure kiln.

Background technology

Present anti-burning normal-pressure boiler mostly is positive and negative sintering structure, and upper grate be anti-the burning, and lower floor's fire grate is for just burning, the boiler of this type of furnace, and the index of discharging fume does not reach environmental requirement.It is very necessary developing a kind of back firing boiler with pure anti-sintering structure at the existing in prior technology problem.

Summary of the invention

Inventing in view of above-mentioned existing in prior technology problem is in order to provide a kind of environment friendly and pollution-free novel double-layer fire grate the anti-atmospheric pressure kiln that burns.

Double-layer grate back described in the utility model burns atmospheric pressure kiln, and its structure is that pond, fire grate, body of heater, water jacket, water tank, outlet flue, shoot door, firing door, clean-out door are formed in the dedusting; Water jacket feeds in the combustion chamber of body of heater inside; Fire grate is divided into upper grate and lower floor's fire grate, and two floor kiln row's two ends are connected with water jacket respectively; Lower floor fire grate below is provided with the chin spoiler that is connected with water jacket.Double-layer grate back described in the utility model burns atmospheric pressure kiln, and upper grate and lower floor's fire grate are triangle water flowing fire grate.

Double-layer grate back described in the utility model burns atmospheric pressure kiln, has adopted pure anti-sintering structure, and chimney can be in smokeless state, and is environment friendly and pollution-free.Fire grate is the water flowing fire grate, and links to each other with water jacket, is combustion apparatus, and heat exchange function is arranged again, can significantly reduce the volume of boiler, has increased the service life of boiler simultaneously.

Description of drawings

The utility model has an accompanying drawing

Fig. 1: double-layer grate back burns the atmospheric pressure kiln structural representation

Among the figure: 1, dedusting pond 2, chin spoiler 3, lower floor's fire grate 4, upper grate 5, water jacket 6, water tank 7, outlet flue 8, shoot door 9, firing door 10, shoot door 11, clean-out door 12, dedusting pond cover plate

The specific embodiment

The specific embodiment that double-layer grate back described in the utility model burns atmospheric pressure kiln as shown in Figure 1, pond 1, fire grate, body of heater 13, water jacket 5, water tank 6, outlet flue 7, shoot door, firing door 9, clean-out door 11 are formed in its structure dedusting; Water jacket 5 feeds in the combustion chamber of body of heater 13 inside; Fire grate is divided into upper grate 4 and lower floor's fire grate 3, and two floor kiln row's two ends are connected with water jacket respectively; Lower floor's fire grate 3 belows are provided with the chin spoiler 2 that is connected with water jacket 5.Upper grate 4 and lower floor's fire grate 3 are triangle water flowing fire grate.During work, coal-fired by on the firing door 9 adding upper grates 4, during burning, flame is passed down through lower floor's fire grate 3, through chin spoiler 2, dedusting pond 1, oppositely upwards enters atmosphere through outlet flue 7 after the dedusting.

Claims (2)

1, a kind of double-layer grate back burns atmospheric pressure kiln, is made up of pond in the dedusting (1), fire grate, body of heater (13), water jacket (5), water tank (6), outlet flue (7), shoot door, firing door (9), clean-out door (11); It is characterized in that water jacket (5) feeds in the inner combustion chamber of body of heater (13); Fire grate is divided into upper grate (4) and lower floor's fire grate (3), and two floor kiln row's two ends are connected with water jacket respectively; Lower floor's fire grate (3) below is provided with the chin spoiler (2) that is connected with water jacket (5).

2, double-layer grate back according to claim 1 burns atmospheric pressure kiln, it is characterized in that upper grate (4) and lower floor's fire grate (3) are triangle water flowing fire grate.
