Description
Technical Field
The invention relates to a collecting device of a burner for solid fuel and a combustion furnace thereof, in particular to a collecting device of a burner using granular biomass solid fuel and a combustion furnace thereof.
Background
From the viewpoint of fuel classification, solid fuel is a combustion material, especially coal, which is most widely used by modern human beings due to abundant resources and safe use. However, as the demand of mineral solid fuels represented by coal increases, resources decrease, and global new energy movement develops, the conventional renewable biomass combustion materials such as straw, wood chips, deadwood, and the like are again highly regarded. With the maturation of the forming technology of the renewable biomass materials, the problems of transportation, storage and the like of the biomass combustion materials are solved, and the use of the biomass combustion materials is popularized in a large range in a short time. The main mode of using the biomass combustion material to popularize at present is to directly use the existing coal-fired burner and the existing combustion stove. However, because of the large difference in the combustion characteristics between biomass-burning materials and mineral-burning materials (such as coal), existing burners and stoves are not suitable for the combustion of solid fuels made of renewable biomass materials.
To this end, the inventor previously proposed an invention patent with application number 200910077637.X (entitled "civil stove"). In the invention, the applicant proposes a civil stove suitable for biomass granular solid fuel according to long-term research on the combustion characteristics of biomass solid combustion materials. The invention comprises a cylindrical burner, a combustion chamber is formed inside the burner; at least a part of the outer side of the lower part of the burner is provided with a collector, the bottom end of which extends to the lower end in the combustion chamber and forms a combustion zone at the bottom end of the burner.
The invention is characterized in that the fuel adding mode is different from the traditional rural firewood range and the fuel adding mode of the coal-fired stove. The invention can realize the continuous filling of fuel under the unpowered condition, and simultaneously can ensure that the fuel can be gradually heated in the combustion process moving to the combustion layer, and a large amount of volatile matters are separated out when the fuel reaches the combustion layer and participate in the combustion of the combustion layer as combustion-supporting gas. The applicant proves through a large number of experiments that the invention patent effectively solves the problem that the existing burner and stove can not adapt to the renewable biomass solid combustion material, so that the combustion efficiency of the biomass is greatly improved. Although the fuel is not gasified in the present invention, the flame for combustion is the same as that of the gas fuel. Test data show that the combustion efficiency of the biomass combustion material can reach 98% by using the stove provided by the invention, and is far higher than the combustion efficiency of a traditional rural firewood stove by 20-30%.
However, in actual use, the fuel supply device of the burner has a problem of small capacity. According to the structure of the fuel supply device of the invention, if the capacity is increased, the volume of the supply device is increased, and the volume is increased, and the fuel is in an uneven state in the furnace, so that the application of the invention in a large-scale heating boiler is limited. Therefore, there is a need for an improved fuel supply apparatus in the invention, so that the invention is advantageous for application in large heat supply boilers.

The biomass combustion material used in the invention has the characteristics of light burning ash and no caking, and accelerates the discharge of the burning ash under the action of the disturbance device, so that subsequent fuel smoothly and uniformly enters the combustion layer to obtain more sufficient combustion effect. The biomass combustion material which is not subjected to molding processing but only subjected to crushing processing can be used, so that the processing cost of the combustion material is greatly saved.

Meanwhile, the biomass combustion material which is not subjected to forming processing can be directly used, so that the processing cost and the combustion cost of the fuel are greatly saved. The invention is more beneficial to the popularization of renewable biomass combustion materials, can completely replace mineral combustion materials such as coal and the like, and is widely applied to large and medium boilers for heat supply in cities or areas with higher environmental requirements.

The bottom end of the material collector 11 extends to the lower part of the cylindrical burner 2, and the grate 12 is arranged below the material collector 11; a combustion zone 13 is formed between the lower end of the burner 2 and the grate 12; an air inlet 17 is formed in the outer side wall of the lower part of the material collector 11 and used for supplying fresh air to the combustion area 13; the air inlets 17 may be provided in plurality and equally arranged along the circumference of the collector 11, so that the supply of fresh air is more uniform. A feeding device 16 is communicated above the material collector 11; a feed inlet 14 communicated with the combustion area 13 is arranged at the lower part of the material collector 11; the biomass solid fuel in the collector 11 enters the lower end of the combustion chamber 21 through the feed inlet 14; the material collector 11 which is arranged around the outer side of the lower end of the burner 2 can be rotatably arranged on a furnace frame 4; the grate 12 is fixedly arranged on the furnace frame 4 below the material collector 11; the disturbing means 15 is a disturbing device fixedly arranged on the grate 12, as shown in fig. 1, which in this embodiment is a disturbing rod (or a disturbing ring) extending into the collector 11; the loading head 11 is rotated relative to the grate 12 by means of a drive 5.
