Abstract

The utility model belongs to a vertical type inverse combusting boiler with double grates. The utility model solves the problem that the existing vertical type hand-coaling boiler can not enlarge thermal power. The utility model is designed into a vertical type inverse combusting boiler with double combustion chambers, and the utility model comprises a boiler body, combustion chambers, the grates of the combustion chambers, coaling wind inlets and smoke outlets. The grates are divided into an upper layer and a lower layer, the combustion chambers are divided into an upper layer combustion chamber and a lower layer combustion chamber by the grates, the inner of the boiler body is provided with two combustion chambers which are spaced to each other and are respectively provided with the coaling wind inlets, and the smoke outlets of the combustion chambers are arranged on the sides of the combustion chambers. The utility model can enhance thermal power of vertical type boilers without enlarging coal throwing distance, and the utility model has the advantages of full combustion, high thermal efficiency, convenient coal throwing, slag removing and ventilation and low cost.

Description

Vertical counter-burning double combustion chamber boiler

The utility model belongs to a kind of vertical counter-burning double grate boiler.

Existing vertical counter-burning double grate boiler, it includes body of heater, combustion chamber and fire grate thereof and coal air inlet, outlet flue, fire grate is two-layer up and down, and the combustion chamber is divided into up and down two-layer combustion chamber, burning enters the lower floor combustion chamber by the combustion chamber, upper strata, flue gas enters the body of heater inner bag by the combustion chamber outlet flue, and is discharged by outlet flue.Its thermal efficiency height, cost is low, floor space is little, fitting operation is convenient, but the thermal power of this kind type of furnace is low.If, then cause manually and can't throw coal, can't operate scarfing cinder and ventilate for improving the area that thermal power strengthens the combustion chamber.Simultaneously also cause the coal of depths fully to burn.

The purpose of this utility model is to address the above problem, and provides that a kind of thermal power is big, sufficient combustion, throwing coal, scarfing cinder, ventilation is convenient, cost is low vertical counter-burning double combustion chamber boiler.

The utility model includes body of heater, combustion chamber and fire grate thereof and coal air inlet, outlet flue, fire grate is two-layer up and down, and the combustion chamber is divided into up and down two-layer combustion chamber, burning enters the lower floor combustion chamber by the combustion chamber, upper strata, flue gas enters flue by the combustion chamber outlet flue, and is discharged by outlet flue, is provided with two combustion chambers that separate each other in body of heater, and the coal air inlet is arranged respectively, the combustion chamber outlet flue is located at the side of combustion chamber.

The utility model can improve the thermal power of vertical boiler, and does not strengthen and throw the coal distance, and sufficient combustion, thermal efficiency height, throwing coal, scarfing cinder, ventilation make things convenient for, cost is low.

Fig. 1 is the utility model embodiment one structural representation;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the utility model embodiment two structural representations;

Fig. 4 is the B-B cutaway view of Fig. 3.

Below in conjunction with accompanying drawing the utility model is further described.

Embodiment one.As Fig. 1, shown in 2, the utility model includes body of heater 16,

combustion chamber

6,8 and 13,10 and

fire grate

7,9,12 and

coal air inlet

17,19, outlet flue 1, fire grate is two-layer up and down, and the combustion chamber is divided into up and down two-

layer combustion chamber

6,13 and 8,10, burning is by combustion chamber,

upper strata

6,13 enter lower

floor combustion chamber

8,10, flue gas enters flue 3 by combustion chamber outlet flue 18, and by outlet flue 1 discharge, in body of heater 16, be provided with two combustion chambers that separate each other 6,8 and 13,10, and coal air inlet 17 arranged respectively, 19, combustion chamber outlet flue 18 is located at the side of combustion chamber.During making, with refractory material 14 and the water layer dividing plate 15 that communicates with flue the combustion chamber is divided into two

combustion chambers

6,8 and 13,10, two shared lower fire gratings 9 in combustion chamber, owing in body of heater, be provided with two

combustion chambers

6,8 and 13,10, can improve thermal power, and not strengthen and throw the coal degree of depth, so sufficient combustion, thermal efficiency height, and throw coal, scarfing cinder, ventilation conveniently.During use, 6,13 coals in the combustion chamber, upper strata, and primary combustion respectively, fuel gas enters lower

floor combustion chamber

8,10, continues to burn, and flue gas enters combustion chamber outlet flue 18 from water layer dividing plate 15 bottoms, and enters flue along the direction of arrow, discharges from outlet flue 1.

As shown in Figure 1, 2, two

combustion chambers

6,8 and 13,10 opposed arrangements, combustion chamber outlet flue 18 is arranged along the both sides, combustion chamber, is convenient to design and manufacturing, reduces the coal degree of depth more, and burning, heat are transmitted evenly.

As shown in Figure 1, upper fire-grating 7,12 is the curved water pipe of U type, and the two ends of the curved water pipe of U type are communicated with flue 3, and surround combustion chamber,

upper strata

6,13 with flue 3.Both improved the thermal efficiency, and made fire grate solid and reliable again.

As shown in Figure 1, outlet flue 1 is located at the top of flue 3, is provided with the transverse tube 2 that communicates with flue in the flue 3, is provided with the water pipe partition wall 5 that communicates with flue in flue 3, two convection pass 4 about water pipe partition wall 5 is divided into flue 3.Make flue gas and transverse tube, flue heat exchange even.

As shown in Figure 1, 2, combustion chamber,

upper strata

6,13 is provided with at least two

coal air inlets

17,19, makes burning more abundant.Be provided with except that cinder notch 11 in the lower floor combustion chamber.

Embodiment two.Shown in Fig. 3,4, outlet flue 1 is located at the sidepiece of flue 3, and mechanical air inducing, is provided with the transverse tube 2 that communicates with flue in the flue 3, is provided with the water pipe partition wall 5 that communicates with flue in flue 3, and water pipe partition wall 5 is the L type, and flue is divided into the flue 4 of turning back up and down.Other structure of present embodiment is identical with embodiment one.
