The flexible tubing is positioned outside the primary air chamber and the iead-in for the moving, rigid tubing through the wall of said primary air chamber is provided with a flexible bellow in order to avoid leakage of primary air along the tube. Hereby the flexible tubing is not subjected to the grate screenings falling down from the grate and the high temperatures thereof.
Description
Technical field
The present invention relates to a kind of cooling fluid circulation system of being illustrated at claim 1 preamble.
Background technology
In this cooling fluid circulation system, well-known, grate beams is arranged to movably, so that the motion of fuel on said fire grate top is provided, and make primary air blow over fire grate from the primary air chamber of fire grate below.Be used for circulating cooling fluid and be usually located at the bottom side of grate beams, so that do not influence the motion of fuel on said fire grate top through the joint of grate beams.In order to allow the motion of removable fire grate beam, before rigid line withdrawed from this primary air chamber, flexible tubing was arranged on inner fire grate below, primary air chamber usually, between pipeline and primary air chamber sidewall, set up thus to be fixedly connected.This cooling fluid circulation system is known in EP0804706 for example, still, does not mention flexible tubing especially.
Summary of the invention
Target of the present invention provides a kind of cooling fluid circulation system of type as stated; Through it; Can avoid flexible tubing to be positioned at the fire grate below; This target is that the cooling fluid circulation system through said type realizes, according to the present invention, said cooling fluid circulation system also comprises the characteristic that the characteristic of claim 1 is illustrated.Through this configuration; It is outside that flexible tubing is positioned at the primary air chamber; Thereby can not receive the influence of the fire grate screening thing that falls down from fire grate and possible high temperature thereof; Pipeline that be used to move, rigidity is provided with flexible bellows through the leading-in end (lead-in) of primary air chamber wall, and primary air is inner from the primary air chamber to leak into the external world along pipe to avoid.The preferred embodiment of cooling fluid circulation system representes that in the dependent claims for a person skilled in the art, the advantage of preferred embodiment is conspicuous after reading following detailed description.
Description of drawings
Below this specification, in the detailed part,, the present invention will be explained in further detail, wherein with reference to like the exemplary embodiment according to cooling fluid circulation system of the present invention shown in the drawings
Fig. 1 is the schematic side-view of the local longitudinal cross-section of burning fire grate that can embodiment of the present invention,
Fig. 2 has illustrated to show the pipeline that is connected in removable fire grate beam according to the present invention,
Fig. 3 illustrate to have shown the leading-in end of rigidity through primary air chamber wall, movable pipe and be used for movably, the pipeline of rigidity is connected to the flexible bellows of the outer setting of primary air chamber wall,
Fig. 4 illustrated to show the lyre form that is connected in series between the inlet that is used to provide the grate beams that is connected in series and the outlet pipe and
Fig. 5 has illustrated to show the pipe of the spiral form that is connected between the inlet that is used to provide the grate beams that is connected in series and the outlet.
The specific embodiment
Used heat burning facility as shown in Figure 1 comprises some grate block I-IV; Each grate block includes the grate beams 1 of downward one-tenth stepped (stepped) and static grate beams in a lateral direction; The grate beams 1 of stepping is downwards extended along the moving direction of fuel on the grate block top, and is arranged to and can alternately moves.Thereby each grate block comprises some grate beams 1 that are arranged on primary air chamber P top, so that the guiding primary air is through the primary air opening in the fire grate.
As shown in Figure 2, removable fire grate beam 1 at one end is provided with travel mechanism 2, is provided with backing roll 3 at a relative end, and thus, removable fire grate beam 1 can move along the longitudinal direction.Grate beams 1 is provided with cooling channels (not showing in detail), and said cooling channels is supplied with cooling fluid through rigid pipe 4, and cooling fluid leaves grate beams through rigid pipe 5.Pipeline 4,5 is connected to inlet collecting 6 and the outlet header 7 that is positioned at a distance, grate beams 1 below.Though be rigidity,, pipeline 4,5 allows the specific minimum movement of grate beams with respect to header 6,7, allows relative less physical between each removable fire grate beam 1 thus.Respective stationary grate beams between removable fire grate beam is correspondingly provided with similar entrance pipe and export pipeline and inlet collecting and outlet header or traditional pipeline and header; But; These are not parts of the present invention, thereby do not describe in detail hereinafter.But said static grate beams is also connected to inlet collecting and exports on the header, and these static inlet collecting are passed primary air chamber wall with the outlet header and are connected to the outside in a conventional manner.
Utilize the pipeline 4,5 of lyre form, spiral form or coiling form, can reduce grate beams respectively and the above-mentioned distance between inlet collecting 6 and the outlet header 7.
When removable fire grate beam 1 moves; Header 6,7 mainly moves along the longitudinal direction of bellows 9,10; Can not hinder opening 11,12; Like this, rigid line 4,5,6,7 is connected in the outside external environment of primary air chamber P in a movable manner, does not have the danger that primary air leaks into outside, primary air chamber.On the position of anchor clamps 15,16 back, a flexible tubing is set, be used for the entrance and exit of cooling fluid is connected to the stationary part of cooling fluid circulation system.
Cooling fluid is convenient in the situation of series circulation at least some grate beams therein; Being connected in series between the inlet of the grate beams that is connected in series and the outlet can be arranged in lyre form, spiral form or the coiling form pipe, so that necessarily relative motion freely between the grate beams that is connected in series is provided.
Though the present invention has been described to specific embodiment in the front, shown in accompanying drawing,, under the situation that does not break away from the equivalent structures book, those skilled in the art can carry out many improvement.This improvement comprises the relevant cooling fluid circulation system of utilizing with other type of removable burning grate beams, for example need not be used for each removable fire grate beam of the independent leading-in end system of independent removable fire grate beam and independent header.
