Abstract
The invention relates to a vertical reciprocating grate, aiming at solving the technical problems that when the grate is transmitted back and forth, the working surface of the grate is in the form of a horizontal flat slope or a flat slope with a small slope angle; accumulated continuous layered distribution is formed on the working face of the grate during the fuel operation period, and fuel operation is realized only by the thrust generated by reciprocating motion of mobile grate sheets relative to fixed grate sheets, thus leading long fuel ignition time, easy generation of lag and coking, and large ventilation resistance, and reducing the combustion effect of a boiler. The technical scheme of the invention is as follows: the vertical reciprocating grate comprises a fixed grate sheet support, a mobile grate sheet support, fixed grate sheets, mobile grate sheets and a reflecting arch, wherein, the fixed grate sheet support and the mobile grate sheet support are vertical support bodies the front sides of which are inclined, the working surface of the reciprocating grate composed of the fixed grate sheets and the mobile grate sheets is in a stepped shape, and the reflecting arch is of a vertical structure and correspondingly matched with the stepped working surface.
Description
Technical field
The present invention relates to boiler grate, particularly relate to a kind of vertical reciprocating grate.
Background technology
At present; the reciprocal drive fire grate of on grate furnace, using; the working face of fire grate is the flat slope face of level or small slope angle (15～20 degree); on the fire grate working face, form the continuous layered distribution of piling up in the operating fuel; the operation of fuel only realizes by the thrust of movable furnace grate plate with respect to the reciprocating motion generation of fixed grate film; owing to touch the front portion on the fuel upper strata of fire grate segment the rear portion on fuel upper strata is not formed resistance; make the fuel lower floor that touches fire grate segment be difficult for driving the operation of fuel upper strata; fuel not only prolongs ignitor firing time; and easily generation is detained; cause the whole coking of fuel upper strata Yi Fasheng; be detained capping; have a strong impact on normal combustion, and cause incinerator screening and stopping accident.Above-mentioned coking because the working face of fire grate is level or flat slope face, can not be eliminated the in service of fire grate, simultaneously, also causes having hindered the ventilation in fuel, and flowing resistance is big, has reduced the boiler combustion effect.
Summary of the invention
The technical problem to be solved in the present invention is the reciprocal drive fire grate of using on the existing grate furnace, the working face of fire grate is the flat slope face of level or small slope angle, on the fire grate working face, form the continuous layered distribution of piling up in the operating fuel, the operation of fuel only realizes by the thrust of movable furnace grate plate with respect to the reciprocating motion generation of fixed grate film, and cause fuel not only to prolong ignitor firing time, and easily produce delay, coking, flowing resistance big, reduced boiler combustion effect or deficiency that can not normal combustion.
For solving the problems of the technologies described above the technical solution used in the present invention be, a kind of vertical reciprocating grate is provided, it is by the fixed grate plate rack, with a fixed grate plate rack left side, moving grate plate rack on right side wall inboard or the grate base is installed the moving grate plate rack that roller cooperates, be fixed on the fixed grate film on the fixed grate plate rack fire grate segment mounting rail, the movable furnace grate plate and the reflection arch that are fixed on the moving grate plate rack fire grate segment mounting rail are formed, described fixed grate plate rack and moving grate plate rack are the vertical support body on slope, front side, fire grate segment mounting rail on described fixed grate plate rack and the moving grate plate rack is distributed in place, slope, described front side, the reciprocal grate working face that described fixed grate film and movable furnace grate plate constitute is stairstepping, and described reflection arch is the vertical reflection arch with the corresponding cooperation of described stairstepping working face.
The present invention compared with the prior art, because back and forth the drive fire grate structure is a vertical reciprocating grate, described reciprocal grate working face is stairstepping, forming the tomography shape along described stairstepping fire grate working face in the operating fuel distributes, between the fuel tomography, anterior fuel tomography does not form resistance to the fuel tomography at rear portion, thrust and the acting in conjunction of fuel self gravitation with respect to the reciprocating motion generation of fixed grate film realizes by movable furnace grate plate in the operation of fuel, make and be on fixed grate film and the movable furnace grate plate fuel and between fixed grate film and movable furnace grate plate, (remove first, tail two fire grate segments) alternately leave, finishing fuel moves on described stairstepping fire grate working face and burns, its beneficial effect is, fuel downward loose shape in running leaves, increased and heat radiation, the acting surface of air, be easy to ignite rapidly, and fuel is not detained, the fuel room that leaves downwards produces bump, the burning that is highly advantageous to rubs, ventilate and anti-coking.Even there is coking to take place to produce impulsive force and be eliminated along with fuel alternately leaves between fixed grate film and movable furnace grate plate, the fuel bed air permeability is good, flowing resistance is little, has improved the boiler combustion effect, and inferior fuel can extensively burn.
