Abstract
The utility model discloses a reformer furnace stair fire grate fuel pushing device which comprises a first drying fire grate, a burning fire grate and a back burning fire grate. A fuel pushing plate is placed on the burning fire grate and the back burning fire grate and placed at a position which is close to the furnace wall. The fuel pushing plate is fixedly connected with a driving device and is pushed by the driving device to do reciprocating motion. According to the reformer furnace stair fire grate fuel pushing device, fuel can be pushed to a lower layer of fire grate at one time, and the fuel is enabled to be effectively and completely burned. The reformer furnace stair fire grate fuel pushing device is simple and reasonable in structure, easy to realize and low in implement cost.
Description
Technical field
The utility model relates to a kind of fire grate device, particularly a kind of reburner step fire grate material-pulling device.
Background technology
What at present, the fire grate device in reburner generally adopted is the cant fire grate that burning boiler is used.Formed by fixed grate and moving grate, during work, reciprocating by moving grate.This fire grate device is used on coal-burning boiler passable, but in the reburner of firing biomass fuel, especially in the reburner take tobacco rod as fuel, little apart from drop due between two-layer fire grate, moving grate can not once be shifted the fuel of upper strata burning on lower floor's fire grate onto, cause the fuel of tobacco rod and so on to fall apart not open, burn insufficient.
Summary of the invention
The purpose of this utility model is to provide a kind of reburner step fire grate material-pulling device, and it is applied on existing step fire grate and the effective profit of fuel can be shifted onto on lower floor's fire grate, makes the burning take tobacco rod as fuel more abundant, complete.
The technical scheme in the invention for solving the above technical problem is: a kind of reburner step fire grate material-pulling device, comprise the dry fire grate of the first order, combustion grate and after-combustion fire grate, be provided with scraping wings on combustion grate and after-combustion fire grate, described scraping wings is arranged on the position near the furnace wall, be fixedly connected with drive unit, promote reciprocating by drive unit.
Compared with prior art, the utility model can with the disposable lower floor's fire grate of shifting onto of fuel, make fuel completing combustion effectively.The utility model is simple and reasonable for structure, is easy to realize, implementation cost is low.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1, a kind of reburner step of the utility model fire grate material-pulling device, comprise the dry fire grate 1 of the first order, combustion grate 2 and after-combustion fire grate 3, be provided with scraping wings 4 on combustion grate 2 and after-combustion fire grate 3, described scraping wings is arranged on the position near the furnace wall, be fixedly connected with drive unit 5, promote reciprocating by drive unit.
During the utility model work, scraping wings on combustion grate 2 is fallen disposable the pushing away of aflame fuel on after-combustion fire grate 3, simultaneously, being arranged on scraping wings on after-combustion fire grate 3 fuel after with charing all pushes away and falls on chain furnace grate, owing in combustion process, fuel bed having been carried out twice promotion, be conducive to the loosening of fuel bed, increased gas permeability and the drying of fuel bed, can make fuel combustion more abundant.
