Accompanying drawing explanation
From the following description of the embodiments of the invention that only provide via limiting examples, and with reference to accompanying drawing, other features and advantages of the present invention will become apparent, wherein:
Fig. 1 is the figure according to boiler of the present invention, and
Fig. 2 to 10 is partial views of boiler, and it shows fluidized bed exchanger supporting system of the present invention.
The specific embodiment
Fig. 1 illustrates boiler, and this boiler comprises the stove 1 of solid particle sustained combustion therein.The top of stove 1 is connected in separating component 2 via extracting pipeline 12 out, extracts pipeline 12 out and transmits flue gas and circulating granular.
Separating component 2 (for example cyclone) delivers gas to the flue 20 starting from its top, and separating component 2 by particle transport to circulating line 23, circulating line 23 leads to the fine and close fluid bed 3 in outside that is placed in stove 1 outside.Circulating line 23 is provided with siphon pipe and insulating barrier substantially.Outside bed 3 is provided with the first heat exchanger 3A, and in this example, the first heat exchanger 3A is the form of one group of pipe, and this group pipe is zigzag in vertical plane, defers to right lateral left lateral and replaces Writing type path, so that long tube sections is preferably level.Supply with coolant fluid, for example water via entrance 39 to the first heat exchanger 3A.The outlet 30 of heat exchanger 3A can be connected in the second heat exchanger 3B that can be arranged in stove 1.
The remainder of describing is devoted to the supporting of heat exchanger 3A.To note, the present invention is not limited to external fluidized bed heat exchanger, but also can use together with other fluidized bed exchanger.
As shown in the perspective view of Fig. 2 and Fig. 3, heat exchanger 3A is included in the multiple pipes 7 (four pipes in this example) that are zigzag in vertical plane.Pipe 7 can have square or circular cross section.Coiled pipe 7 is deferred to each right lateral left lateral and is replaced Writing type path.It is a kind of two-way literal that right lateral left lateral is alternately write, the most common in manuscript and other inscription in ancient times.Word reverses in every line or puts upside down, and letter also turns around.Unlike current english from left to right, or as Arabic and Hebrew from right to left, must read the alternate row of right lateral left lateral in alternately writing in the other direction.Title " right lateral left lateral is alternately write " is gained the name from Greek.Its etymology is from bous, " bull ", and strephein, " rotation ", this is because writer's hand draws plough and advances back and forth across field as bull, and changes direction at the end of every row with along returning to (, " as public cattle hauling plough ") in the other direction.With which, canal path is alternately advanced from right to left and from left to right.
Two or more different supporting arrangements 41,42 that separated by clearance spaces are realized the supporting of fluidized bed exchanger beam tube.A device 41 is positioned at the left side of interchanger, and another device 42 is positioned at the right side of interchanger.Each device 41,42 comprises at least two vertical support parts 411,412; 421,422 (they are separated by clearance spaces, and are two swing pipes closely), and the interference chuck support of alternately welding, can regulate its position according to mechanical calculations result.Swing pipe 411,412; 421,422 can be cooled, as intrafascicular in high temperature superheater (HTS).Alternatively, swing pipe 411,412; 421,422 can not be cooled, as intrafascicular in medium temperature overheater (ITS).
Fig. 4 illustrates the fixing point 6 between pipe 7 and vertical tube 411,412,421,422.
As shown in Figure 5, the fixing point 6 of pipe 7 is by circle expression, and for each supporting arrangement 41,42, each horizontal component of each exchanger tube 7 is preferably fixed on an only vertical tube of supporting arrangement 41,42.This allows to reduce the bending stress in interchanger.In addition, in order to reduce bending stress, as shown in Figure 6, for each supporting arrangement 41,42, two continuous horizontal components of pipe 7 (, be placed in the horizontal component of the pipe before the bend that right lateral left lateral replaces Writing type path, and be placed in bend horizontal component below) be not preferably fixed on identical vertical tube.
In Fig. 7, show the first fixing embodiment consistent with these optimum conditions.In left side, the first supporting arrangement 41 comprises two vertical support parts 411,412, that is, and and a left supporting member 411 and a right support part 412.In an identical manner, on right side, the second supporting arrangement 42 comprises two vertical support parts 421,422, that is, and and a left supporting member 421 and a right support part 422.Tube bank comprises five pipes 71 to 75.Pipe 71,72,73,74,75 is deferred to and is comprised that the right lateral left lateral of four bend A, B, C, D replaces Writing type path.Certainly, provide the quantity of pipe and the quantity of bend via example, and those skilled in the art can select pipe and the bend of varying number.
If consider pipe 71 (that is, being numbered the pipe of N), this pipe 71 is connected in the right support part 412 of the first supporting arrangement 41 before bend A, and after bend A, is connected in the left supporting member 411 of the first supporting arrangement 41.After bend A, pipe 71 is then connected in the left supporting member 421 of the second supporting arrangement 42, and after bend B, is connected in the right support part 422 of the second supporting arrangement 42 before bend B.Then, repeat identical connection mode: pipe 71 is connected in the right support part 412 of the first supporting arrangement 41 before bend C, and after bend C, is connected in the left supporting member 411 of the first supporting arrangement 41.Then, pipe 71 is connected in the left supporting member 421 of the second supporting arrangement 42 before bend D, and after bend D, is connected in the right support part 422 of the second supporting arrangement 42.
According to this first embodiment, pipe 72 and 74 (that is, being numbered the pipe of N+1) connect in contrary mode,, being connected of the right support part 412 of pipe N and the first supporting arrangement 41 managed N+1 and replace with being connected of left supporting member 411 of the first supporting arrangement 41, and vice versa.In an identical manner, being connected of the right support part 422 of pipe N and the second supporting arrangement 42 managed N+1 and replace with being connected of left supporting member 421 of the second supporting arrangement 41, and vice versa.
In Fig. 8, show the second embodiment.According to this embodiment, all pipes 71 to 75 are connected in the right support part 412 of the first supporting arrangement 41 before bend A.Therefore, all pipes 71 to 75 are connected in the left supporting member 411 of the first supporting arrangement 41 after bend A.In an identical manner, all pipes 71 to 75 are connected in the right support part 422 of the second supporting arrangement 42 before bend B and after bend A.Therefore, all pipes 71 to 75 are connected in the left supporting member 421 of the second supporting arrangement 42 after bend B.
Fig. 9 and Figure 10 show respectively the third and fourth embodiment.Therefore, instructed those skilled in the art can carry out various structures.These structures are consistent with two kinds of situations shown in Fig. 5 and Fig. 6, , 1) at least one supporting arrangement, and preferably for two supporting arrangements, each horizontal component of exchanger tube is fixed on an only vertical tube of supporting arrangement, and 2) for each supporting arrangement, and preferably for two supporting arrangements, two continuous horizontal components of exchanger tube (, be placed in the horizontal component of the pipe before the bend that right lateral left lateral replaces Writing type path, and be placed in bend horizontal component below) be fixed on the different vertical tube of supporting arrangement.
