Abstract

The utility model discloses a kind of embedded boiler bunker bay, connected with boiler, on boiler frame, boiler bunker bay is embedded on boiler frame for boiler erection, it is made up of bunker bay A groups and bunker bay B groups, bunker bay A groups and bunker bay B groups are arranged symmetrically in the both sides of boiler;Bunker bay A groups and bunker bay B groups form by 8 raw coal buckets and a bed bucket, and raw coal bucket connects with bed bucket with boiler.Compared with prior art, the utility model has advantages below:1. all raw coal buckets are conveyed in raw coal Fuel Process to boiler coal feeding mouth only need to set one-level feeder, equipment investment expense caused by excessive use feeder is effectively reduced;2. raw coal bucket is more or less the same with corresponding each coal feeding hole to coal distance, and shorter, the risk of feeder chain abjection is reduced, while the response time of load can have been reduced to coal, this is beneficial to the regulation of boiler load.

Description

A kind of embedded boiler bunker bay
Technical field
Bunker bay is the utility model is related to, more particularly to a kind of embedded boiler bunker bay.
Background technology
Traditionally, the arrangement of thermal power plant's bunker bay has the modes such as preceding coal bunker, side coal bunker, rear coal bunker.And for most Several coal-burning power plants, the arrangement on bunker bay are preferentially adopted typically according to the concrete condition of engineering in foregoing arrangement With.But above arrangement generally existing following problems:1st, most of coal feeding hole need to set two-stage feeder, it will certain Coal controllability is given during being reduced in degree to coal;2nd, the coal feeding hole of rear wall and furnace side rearward to coal apart from long, increase The risk of feeder chain abjection, while can be longer to the response time of load to coal, this will be to the behaviour of regulation boiler load Have adverse effect on;3rd, indivedual feeders need to take into account 3 coal feeding holes, feeder contribute it is excessive, and be difficult to ensure that it is each to Coal mouth gives coal uniformity, and reliability is also difficult to be guaranteed.
Utility model content
The purpose of this utility model is, there is provided a kind of embedded boiler bunker bay, can shorten raw coal bucket and boiler it Between distance, the response time of load can have been reduced to coal, this is beneficial to the regulation of boiler load.
In order to solve the above technical problems, the utility model adopts the following technical scheme that:
A kind of embedded boiler bunker bay, is connected with boiler, and on boiler frame, boiler bunker bay is embedded in for boiler erection On boiler frame, it is made up of bunker bay A groups and bunker bay B groups, bunker bay A groups and bunker bay B groups are arranged symmetrically in the two of boiler Side;Bunker bay A groups and bunker bay B groups form by 8 raw coal buckets and a bed bucket, and raw coal bucket and bed bucket connect with boiler It is logical.Each raw coal bucket is provided with independent feeder.
In a kind of foregoing embedded boiler bunker bay, bunker bay A groups and bunker bay B groups by two three points of storehouse coal bunkers, One two points of storehouse coal bunker and a bed bucket composition, three points of storehouse coal bunkers include three raw coal buckets, and two points of storehouse coal bunkers include two originals Coal bunker.
In a kind of foregoing embedded boiler bunker bay, the raw coal bucket of bunker bay A groups and the raw coal bucket of bunker bay B groups are logical Independent pipeline is crossed to connect with boiler.
In a kind of foregoing embedded boiler bunker bay, coal feeding hole is equipped between each raw coal bucket and boiler, is each given Feeder is equipped with coal mouth.
In a kind of foregoing embedded boiler bunker bay, each bed bucket connects four coal feeding holes.
Compared with prior art, the utility model has advantages below:
1. all raw coal buckets are conveyed in raw coal Fuel Process to boiler coal feeding mouth only need to set one-level feeder, effectively reduce Equipment investment expense caused by excessive use feeder;
2. raw coal bucket is more or less the same with corresponding each coal feeding hole to coal distance, and shorter, feeder chain is reduced The risk of bar abjection, while the response time of load can have been reduced to coal, this is beneficial to the regulation of boiler load;
3. each coal feeding hole configures single feeder, and each coal feeding hole corresponds to single raw coal bucket, and this will change significantly It has been apt to the uniformity to coal, and has enhanced the reliability to coal.
4. combining the advantages of side coal bunker embeds coal bunker arrangement with boiler steel frame, machine, stove spacing are shortened, is reduced The volume and floor space of main building, reduce the dosage of the materials such as four big pipelines and cable of costliness.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the present utility model.
Reference:1- bunker bay A groups, 2- bunker bay B groups, 3- boilers, 4- coal feeding holes, 5- tri- divide storehouse coal bunker, and 6- two divides Storehouse coal bunker, 7- bed buckets, 8- raw coal buckets.
The utility model is further described with reference to the accompanying drawings and detailed description.
Embodiment
Embodiment 1 of the present utility model:As shown in figure 1, a kind of embedded boiler bunker bay, is connected, boiler 3 with boiler 3 On boiler frame, boiler bunker bay is embedded on boiler frame, is made up of bunker bay A groups 1 and bunker bay B groups 2, coal bunker Between A groups 1 and bunker bay B groups 2 be arranged symmetrically in the both sides of boiler 3;Bunker bay A groups 1 and bunker bay B groups 2 are by 8 raw coal buckets 8 Formed with a bed bucket 7, raw coal bucket 8 connects with bed bucket 7 with boiler 3.
The raw coal bucket 8 of bunker bay A groups 1 is connected with the raw coal bucket 8 of bunker bay B groups 2 by independent pipeline with boiler 3. Coal feeding hole 4 is equipped between each raw coal bucket 8 and boiler 3, feeder is equipped with each coal feeding hole 4.Each bed bucket 7 connects Lead to four coal feeding holes 4.
Embodiment 2:As shown in figure 1, a kind of embedded boiler bunker bay, is connected with boiler 3, boiler 3 is arranged on boiler frame On frame, boiler bunker bay is embedded on boiler frame, is made up of bunker bay A groups 1 and bunker bay B groups 2, bunker bay A groups 1 and coal bunker Between B groups 2 be arranged symmetrically in the both sides of boiler 3;Bunker bay A groups 1 and bunker bay B groups 2 are by 8 raw coal buckets 8 and a bed bucket 7 Composition, raw coal bucket 8 and bed bucket 7 connect with boiler 3.
Bunker bay A groups 1 and bunker bay B groups 2 are by two three points of storehouse coal bunkers, 5, two points of storehouse coal bunkers 6 and a bed bucket 7 compositions, three points of storehouse coal bunkers 5 include three raw coal buckets 8, and two points of storehouse coal bunkers 6 include two raw coal buckets 8.The raw coal of bunker bay A groups 1 Bucket 8 is connected with the raw coal bucket 8 of bunker bay B groups 2 by independent pipeline with boiler 3.Between each raw coal bucket 8 and boiler 3 Provided with coal feeding hole 4, feeder is equipped with each coal feeding hole 4.Each bed bucket 7 connects four coal feeding holes 4.
A kind of operation principle of embodiment of the present utility model:
1. the bed supply of the startup stage of boiler 3.
In order that the inside of boiler 3 produces fluidisation field and carries out combustion process in boiler 3 to coal in order to follow-up, in bilateral coal One bed bucket 7 is individually set in storehouse, and it is defeated to the inside of boiler 3 by two-stage feeder in the startup stage of boiler 3 Send bed.In addition, in order to realize the more preferable internal fluidisation field of boiler 3, two bed buckets 7 by feeder respectively with boiler On four coal feeding holes 4 be connected, i.e., carry out conveying bed by 8 coal delivery mouths.
2. boiler normally gives the coal combustion stage.
After the startup stage of boiler 3 implements stabilization, the raw coal fuel in each raw coal bucket 8 is only by one-level feeder Be transported to what is burnt inside boiler 3, and the coal feeding hole 4 of boiler 3 that 8 correspondences of each raw coal bucket are single, realize boiler 3 to While coal uniformity, the reliability to coal process also ensure that.
