Abstract
The utility model relates to the technical field of boilers, in particular to a chain-grate boiler with gas fume recirculation. The chain-grate boiler comprises a boiler body, a combustion chamber body, a chain grate, an ash bucket and a circulation fan. The chain grate is arranged in the boiler body, the ash bucket is arranged in the boiler body below the chain grate, and the combustion chamber body is arranged at the upper end of the boiler body corresponding to the chain grate. A chimney is fixedly installed at the upper end of the combustion chamber body, an air inlet pipe is arranged on the combustion chamber body, the circulation fan is arranged on the outer side of the boiler body, an air inlet of the circulation fan is communicated with the chimney through an air inlet pipeline, and an air outlet of the circulation fan is communicated with the boiler body located above the chain grate through a first pipeline. The chain-grate boiler is reasonable in structure and convenient to use, the circulation fan is arranged to circulate hot gas fume again into the boiler body and the combustion chamber, and under the condition that ventilation speed is not reduced, the excess air coefficient is reduced. The oxygen content of the gas fume is reduced, losses caused by gas fume exhausting are reduced, the combustion gas fume and air in the combustion chamber are evenly mixed, volatile matter is sufficiently combusted, and the blackness degree of the chimney is reduced.
Description
Technical field
The utility model relates to boiler technology field, is a kind of flue gas recycled chain-grate boiler.
Background technology
Chain-grate boiler be the air-supply of logical storehouse or segmentation to wind, it gives controllability of wind poor, wants often the place of wind few on the contrary to wind, the place of a small amount of wind large to air quantity on the contrary, therefore unbalanced to wind.And fire grate bottom ash bucket leaks out a little manyly, mix in burner hearth flue gas and air inhomogeneously, even volatile matter all cannot burn completely, so has that excess air coefficient is higher, the mean temperature of burner hearth is low, a large amount of over-emitting black exhausts of chimney, and flying dust granularity is large.
Summary of the invention
The utility model provides a kind of flue gas recycled chain-grate boiler, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the incomplete problem of chain boiler combustion.
The technical solution of the utility model is achieved like this: a kind of flue gas recycled chain-grate boiler, comprise body of heater, hearth body, traveling-grate stoker, ash bucket and circulating fan, in body of heater, be provided with traveling-grate stoker, in body of heater below traveling-grate stoker, be provided with ash bucket, upper end at the body of heater corresponding with traveling-grate stoker is provided with hearth body, upper end at hearth body is installed with chimney, on hearth body, be provided with blast pipe, in body of heater outside, there is circulating fan, the air inlet of circulating fan communicates with chimney by air inlet pipeline, on the air outlet of circulating fan, by the first pipeline, communicate with the body of heater that is positioned at traveling-grate stoker top.
The air outlet of above-mentioned the first pipeline tilts towards traveling-grate stoker direction.
On the air outlet of above-mentioned circulating fan, by the second pipeline, communicate with the body of heater that is positioned at traveling-grate stoker below.
On the air outlet of above-mentioned circulating fan, by the 3rd pipeline, communicate with blast pipe.
In the chimney of above-mentioned air inlet pipeline below, be installed with air preheater.
The utility model is rational in infrastructure, easy to use, by circulating fan is set, hot flue gas is circulated in body of heater and burner hearth again, is not reducing under ventilation speed condition, reduce excess air coefficient, reduce Oxygen Amount in Flue Gas, reduce flue gas loss, stove chamber inner combustion flue gas and air are mixed, volatile matter fully burns, and reduces chimney blackness.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks perspective structure schematic diagram.
Coding in figure is respectively: 1 is body of heater, and 2 is hearth body, and 3 is traveling-grate stoker, and 4 is ash bucket, and 5 is circulating fan, and 6 is chimney, and 7 is blast pipe, and 8 is air inlet pipeline, and 9 is the first pipeline, and 10 is the second pipeline, and 11 is the 3rd pipeline, and 12 is air preheater.
The specific embodiment
As shown in Figure 1, this flue gas recycled chain-grate boiler comprises body of heater 1, hearth body 2, traveling-grate stoker 3, ash bucket 4 and circulating fan 5, in body of heater 1, be provided with traveling-grate stoker 3, in body of heater 1 below traveling-grate stoker 3, be provided with ash bucket 4, upper end at the body of heater corresponding with traveling-grate stoker 31 is provided with hearth body 2, in the upper end of hearth body 2, be installed with chimney 6, on hearth body 2, be provided with blast pipe 7, in body of heater 1 outside, there is circulating fan 5, the air inlet of circulating fan 5 communicates with chimney 6 by air inlet pipeline 8, on the air outlet of circulating fan 5, by the first pipeline 9, communicate with the body of heater 1 that is positioned at traveling-grate stoker 3 tops.Like this, by circulating fan 5 is set, hot flue gas is circulated in body of heater 1 again, is not reducing under ventilation speed condition, reduce excess air coefficient,, reduce Oxygen Amount in Flue Gas, reduce flue gas loss, the interior combustion product gases of burner hearth 2 and air are mixed, and volatile matter fully burns, and reduces chimney blackness.
As shown in Figure 1, in order to improve efficiency of combustion, the air outlet of the first pipeline 9 tilts towards traveling-grate stoker 3 directions.
As shown in Figure 1, in order to improve efficiency of combustion, on the air outlet of circulating fan 5, by the second pipeline 10, communicate with the body of heater 1 that is positioned at traveling-grate stoker 3 belows.
