Abstract
The invention discloses a boiler grate, the front part of a grate body of a grate furnace is arranged outside the front wall of a hearth with a combustible gas inlet generated by a primer percussion generation device, part of the front section of the grate body outside the front wall of the hearth and a square furnace tube the upper-middle part of the back sidewall of which is provided with a combustible gas outlet generated by a primer generation device and the upper part thereof is fixed on the side wall of the grate form the primer generation device, the square furnace drum is a diaphragm type walled structure and fixed on the side wall of the grate, cooling water pipe on the diaphragm type wall is connected with a small collecting box which is arranged on the diaphragm type wall, the small collecting box is connected with a boiler collecting box, part of the back section of the grate outside the hearth front wall is coal receiving section on which no feed wind direction arrives at the section and carries out coal distributing on the primer, and between the upper part of the grate, the lower edge of the back side wall of the square furnace drum and the lower edge of the front wall of the hearth, gaps used for controlling the coal-conveying height are respectively provided. The invention has the beneficial effects that: structure is simple; and combustion is from bottom layer to upper layer, which is the same as ventilation direction.
Description
Technical field
The present invention relates to a kind of boiler grate.
Background technology
The coal-fired fire grate of the mechanization of widespread usage at present causes burn incompletely; Cause waste.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of boiler grate is provided.
Technical scheme of the present invention is: a kind of boiler grate, it is characterized in that: grate furnace fire grate body front portion is located to have outside the burner hearth front wall that fire in a stove before fuel is added device generation fuel gas inlet takes place, the outer fire grate body portion front section of burner hearth front wall and be fixed in rear wall middle and upper part on the fire grate body sidewall above it and have and the block furnace tube that fire in a stove before fuel is added device produces the fuel gas outlet takes place form generation fire in a stove before fuel is added device, the block furnace tube is that membrane wall structure and fire grate body sidewall are fixed, cooling water pipe is connected with little collection case on it on the membrane wall, little collection case is connected with boiler header, section is not subjected to the coal section for having to what wind direction arrived cloth coal on this section fire in a stove before fuel is added after the outer fire grate body portion of burner hearth front wall, above the fire grate body with block furnace tube rear wall lower edge, the slit that the defeated coal height of control is arranged respectively between the burner hearth front wall lower edge.
Beneficial effect of the present invention: simple in structure; Burning is identical with direction of ventilation to the upper strata by bottom.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment: a kind of boiler grate, grate furnace fire grate body 1 front portion is located to have outside the burner hearth front wall 3 that fire in a stove before fuel is added device generation fuel gas inlet 2 takes place, burner hearth front wall 3 outer fire grate body portion front section 4 and be fixed in rear wall middle and upper part on fire grate body 1 sidewall above it and have and block furnace tube 6 that fire in a stove before fuel is added device produces fuel gas outlet 5 takes place form fire in a stove before fuel is added devices take place, block furnace tube 6 is fixed for membrane wall structure and fire grate body 1 sidewall, cooling water pipe and little collection case 7 on it on the membrane wall, 8 connect, little collection case 7,8 are connected with boiler header, section is not subjected to coal section 9 for having to what wind direction arrived cloth coal on this section fire in a stove before fuel is added after the burner hearth front wall 3 outer fire grate body portions, above the fire grate body 1 with block furnace tube 6 rear wall lower edges, the slit 10 that the defeated coal height of control is arranged respectively between burner hearth front wall 3 lower edges, 11.
