Description
Technical field
The utility model is related to field of combustion technology, and in particular to a kind of new pulverized-coal fired boiler feed arrangement and one kind
New boiler.
Background technology
Pulverized-coal fired boiler is a kind of conventional energy conversion, its operation principle be by inputting coal dust into boiler, and
Coal dust is set to carry out heat energy output after burning in the boiler；Therefore can be provided with pulverized-coal fired boiler is used to coal dust being delivered to boiler combustion
Burn the feed arrangement in room；In the prior art, its feed arrangement is that coal dust is fed directly in combustion chamber, and it usually can
The imperfect combustion of coal dust is caused, the gas of pollution air, and the low problem of coal utilization is produced.
The content of the invention
To overcome drawbacks described above, the purpose of this utility model be to provide a kind of new pulverized-coal fired boiler feed arrangement with
And a kind of new boiler.
The purpose of this utility model is achieved through the following technical solutions：
The utility model is a kind of new pulverized-coal fired boiler feed arrangement, and it is connected with the combustion chamber in boiler, including：
For the feed pipe of pulverized coal conveying, the port of export of the feed pipe and the combustion chamber are connect on the feed pipe
There is catalyst dropper, the catalyst dropper includes：Pin and capsule portion are dripped, the lower end of the drop pin is stretched into the feed pipe, and
Its upper end is connected with the lower end in capsule portion, and the upper end in the capsule portion is connected by conduit with catalyst container, the capsule portion
Cross-sectional area be all higher than the cross-sectional area of the drop pin and conduit.
A kind of new boiler of the utility model, including：Combustion chamber and feed arrangement as described above, the feed arrangement
The port of export of middle feed pipe is arranged at the top of the combustion chamber.
Further, the quantity of the feed arrangement is four, and it is respectively arranged at four sides of the combustion chamber.
The utility model is connected to catalyst dropper in coal dust feed pipe, makes coal dust before combustion chamber is entered first with being catalyzed
Agent is mixed, and it contributes to the abundant burning of coal dust, reduces the generation of dusty gas, improves the utilization rate of coal dust.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following preferred embodiments and accompanying drawing.
Fig. 1 is the structural representation of the utility model feed arrangement；
Fig. 2 is the overlooking the structure diagram of the utility model boiler；
Fig. 3 is the dimensional structure diagram of the utility model boiler.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further described.It should be appreciated that specific embodiment described herein is only to explain this reality
With new, it is not used to limit the utility model.
Referring to Fig. 1, the utility model is a kind of new pulverized-coal fired boiler feed arrangement, itself and the combustion chamber 1 in boiler
It is connected, including：For the feed pipe 2 of pulverized coal conveying, the port of export 6 of the feed pipe 2 is connected with the combustion chamber 1,
Catalyst dropper is connected on the feed pipe 2, the catalyst dropper includes：Drip pin 3 and capsule portion 4, the lower end of the drop pin 3
Stretch into the feed pipe 2, and its upper end is connected with the lower end in capsule portion 4, the upper end in the capsule portion 4 passes through conduit 5 and catalysis
Agent container is connected；It is easy to observe the output speed and output state of catalyst, the cross-sectional area in the capsule portion 4 in the capsule portion 4
It is all higher than the cross-sectional area of the drop pin 3 and conduit 5.
In the utility model, coal dust is transported in combustion chamber 1 by feed pipe 2, and coal dust is by drop pin 3
During lower section, will be added the coal dust in catalyst, addition after catalyst will be more conducive to burn；And in order to ensure to be sent to burning
Coal dust in room 1 can be added to catalyst, and prevent catalyst from influenceing its effect because long-time is in contact with external environment, therefore
The utility model is using the design that catalyst is added in feed pipe 2.
Refer to Fig. 2 to Fig. 3, a kind of new boiler of the utility model, including：Combustion chamber 1 and charging as described above
The port of export 6 of feed pipe 2 is arranged at the top of the combustion chamber 1 in device, the feed arrangement.
Further, the quantity of the feed arrangement is four, and it is respectively arranged at four sides of the combustion chamber 1.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
