Problems solved by technology

[0002] Powdery combustible materials widely exist in various fields of industrial and agricultural production, such as biomass powder (wood chips, wood shavings, fruit shells, straw, etc.), powdery combustible materials produced in the process of gasification and cracking of waste rubber and plastics, waste disposal process The generated powdery combustible materials and fuel powders such as coal powder contain a lot of heat energy, and a large amount of disposal will not only cause a great waste of energy, but also cause serious pollution to the environment
[0003] There are many reasons why powdery combustible materials cannot be fully utilized, among which the more important reasons are as follows: 1. The traditional grate is composed of furnace bars, and there are gaps between the furnace bars for ventilation, so this kind of grate It cannot support powdery combustible materials, and cannot create conditions for powdery combustible materials to burn; 2. Powdery combustible materials have poor air permeability, slow and insufficient combustion, easy flameout, and low utilization efficiency
3. Powdery combustible materials are easy to feed but difficult to ash out during the combustion process. The combustion structure of the powdery combustible materials is easily damaged during the ash removal process, resulting in flameout
[0004] In order to solve the above-mentioned technical problems, the powdery combustible materials in the prior art can only be burned by injection, and its disadvantages are: 1. The requirements for the particle size and consistency of the powdery combustible materials are relatively high, resulting in the application of injection technology. Limitations; 2. The ashes after burning turn into dust, causing secondary air pollution; 3. The equipment required for injection combustion is complicated, which is not conducive to popularization and application

Embodiment 1

[0030] Embodiment one: if figure 1 , figure 2 and image 3 As shown, the powdery combustible material combustion grate is installed in the furnace or combustion chamber of the boiler or other combustion equipment, and the powdery combustible material is burned to obtain and utilize the heat energy contained in the powdery combustible material. This embodiment includes a plurality of fixed furnace plates 1 arranged in steps from high to low and parallel to each other. The fixed furnace plates 1 are elongated flat plates without holes on the surface. In this embodiment, all the fixed furnace plates 1 are arranged horizontally, fixed side plates 2 connecting the fixed furnace plate 1 are respectively installed on both sides of the fixed furnace plate 1, and a gas distribution device is installed on the upper surface of the fixed furnace plate 1. The function of the gas device is to provide enough air for the powdery combustible materials with poor air permeability; Pushing ma...

Embodiment 2

[0037] Embodiment two: if Figure 8 As shown, this embodiment is basically the same as Embodiment 1, except that the fixed furnace plate 1 is arranged obliquely and the inner end of the fixed furnace plate 1 is higher than the discharge end, and the corresponding pushing furnace plate 3 Also along with the fixed furnace plate 1 being inclined, the reciprocating motion track of the reciprocating drive device is also inclined along with the fixed furnace plate 1 .

[0038] The advantage of this embodiment is to facilitate the flow of materials and prevent the materials from being brought back by the pushing furnace plate 3 .

Abstract

The invention discloses a powder combustible material combustion fire grate which comprises at least two fixed grate plates which are in a stepped form. A gas distributing device is mounted on the upper surface of each fixed grate plate. A pushing grate plate which can reciprocate is mounted at the rear of each fixed grate plate. The powder combustible material combustion fire grate has the advantages that the fixed grate plates serve as support plates for powder combustible materials, and powder combustion balls can be built on the fixed grate plates easily; combustion-supporting gas is provided upwardly from the bottoms of the powder combustion balls by the gas distributing device, a plurality of combustion-supporting gas passages are created in each powder combustion ball, and fully combustion of the powder materials is guaranteed; and by the stepped fixed grate plate and the pushing grate plate which can reciprocate, combustion balls of the powder combustible materials from top to bottom can be built after rolling and loosening without fully damaging original combustion balls, combustion is complete and efficient, no flying dust is created, and environment protection is facilitated.
