Abstract

The utility model discloses a grate of a boiler burning biomass charcoal. The grate comprises a grate frame, boiler holes, and grate fins, wherein the boiler holes have a round, rectangular, square and triangular shapes; the diameter D of each round boiler hole is not smaller than 20 mm and not larger than 80 mm; and the diameter D of the inscribed circle of each rectangular, square and triangular boiler hole is not smaller than 20 mm and not larger than 80 mm. According to the technical scheme, the boiler grate has the proper pore diameter to prevent type charcoals not burned out from dropping from the grate, and has good ventilation effect, thereby saving energy and ensuring sufficient burning of the charcoal.

Description

A kind of boiler grate that burns biomass charcoal

Technical field:

The present invention relates to boiler and make the field, specifically refer to a kind of boiler grate that burns biomass charcoal.

Technical background:

The mode that molded coal boiler adds moulded coal has horizontal direction and vertical direction, and the molded coal boiler major part more than 1 ton is a horizontal direction.On the fire grate outside fire door, on moulded coal was vertically built one by one, fire grate fire door is outer with mechanical equivalent of light feeding device advanced burner hearth.The aperture of the fire grate firehole of existing molded coal boiler more than 80mm, is because the clay content 35～50% of moulded coal (as honeycomb briquette) after the burning-out, resembles a common brick generally.The clay content height is difficult for scattering, and the clay content height has significantly reduced the calorific capacity of moulded coal.(number of patent application: 200910042736.4 and 201010217927.2), caloric value is more than 1.5 times of common moulded coal to biomass charcoal.This type charcoal is done adhesive meter without clay, but uses cement, and the content of cement is 5---in 15%, after the burning-out, become white powder.If use existing moulded coal fire grate to burn biomass charcoal, the aperture is too big, and biomass charcoal will occur does not have burning-out just to fall into below the fire grate, waste about energy more than 15%.And can fire grate burn bending; The aperture of fire grate is too little, draws badly, and influences the biomass charcoal burning.

Summary of the invention:

The object of the present invention is to provide a kind of boiler grate that can burn biomass charcoal, and energy savings; The biomass charcoal sufficient combustion.

The object of the present invention is achieved like this, and the boiler grate that this burns biomass charcoal comprises fire grate frame, fire grate hole, fire grate rib, and described fire grate hole is circular, and round kiln round diameter is 15mm≤D≤80mm;

The boiler grate that this burns biomass charcoal comprises fire grate frame, fire grate hole, fire grate rib, and the fire grate hole is rectangle, square, triangle, and described rectangle, square, triangle fire grate hole inscribed circle bore dia are 20mm≤D≤80mm.

Because this burns the boiler grate of biomass charcoal, described round kiln round diameter is 15mm≤D≤80mm; Described rectangle, square, triangle fire grate hole inscribed circle bore dia are 15mm≤D≤80mm.Use the boiler grate of this burning biomass charcoal, pore size is moderate, and biomass charcoal can not occur does not have burning-out just to fall into below the fire grate energy savings; Furnace grate ventilation is good, the biomass charcoal sufficient combustion.

Down for the invention will be further described in conjunction with the accompanying drawings:

Description of drawings:

Fig. 1 mechanical equivalent of light feeding device and boiler grate syndeton schematic diagram;

Fig. 2 rectangle boiler grate structural representation;

The circular boiler grate structural representation of Fig. 3;

Fig. 4 square boiler grate structural representation;

Fig. 5 triangle boiler grate structural representation;

The specific embodiment:

With reference to the accompanying drawings 1---accompanying drawing 5, the boiler grate that this burns biomass charcoal comprises fire grate frame 7, fire grate hole 9, fire grate rib 8, and there are circle, rectangle, square, triangle in fire grate hole 9, and described round kiln round 9 diameters are 15mm≤D≤80mm; Described rectangle, square, triangle fire grate hole 9 inscribed circle diameter D are 15mm≤D≤80mm.

Rectangle fire grate 2 is to be made of metal, and inscribed circle is only tangent with the long limit of rectangle.

Circular apertures fire grate 2 is to be made of metal, and is drilled with many circular holes on the fire grate, and the orientation in hole is identical with type charcoal direction.

Tri-angle-holed fire grate 2 is to be made of metal, and is welded with various triangles by stove frame 5, and inscribed circle and three limits are tangent.

Square fire grate 2 is to be made of metal, and inscribed circle and four limits are tangent.

The pushing ram of mechanical equivalent of light feeding device 1 is near fire grate 2, and mechanical equivalent of light feeding device 1 advances fulcrum 6 to be connected with fire grate 2, stacking type charcoal 3 on the fire grate 2, and fire grate 2 is bearing on the track of boiler 4.

Claims (2)

1. a boiler grate that burns biomass charcoal comprises fire grate frame, fire grate hole, fire grate rib, and the fire grate hole is circular, it is characterized in that described round kiln round diameter is 20mm≤D≤80mm.

2. boiler grate that burns biomass charcoal, comprise fire grate frame, fire grate hole, fire grate rib, the fire grate hole is rectangle, square, triangle, it is characterized in that, described rectangle, square, triangle fire grate hole inscribed circle bore dia are 20mm≤D≤80mm.
