Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.

[0026] The main innovation of the present invention is that a combined fire grate consisting of a fixed fire grate 601 and a rotating fire grate 602 is used in the combustion basin 201, and the structure of the grate teeth in the prior art is changed at the same time, avoiding the continuous fire grate. Severe deformation caused by the alternation of cold and heat of the grate teeth during heating operations; meanwhile, the grate teeth 6022 of the rotating grate 602 used in the present invention are simple in structure and easy to manufacture, and are convenient for casting. The working mode of the rotating grate 602 in the present invention is not only applicable to The grate teeth 6022 made of cast iron and the grate teeth 6022 made of ordinary carbon steel will not be seriously deformed and affect the use.

[0027] Such as Figure 1~4 As shown (in...

Abstract

The invention relates to the technical field of heating and combustion equipment, in particular to an automatic biomass particle heating furnace. The automatic biomass particle heating furnace comprises a fixed grate which is composed of a plurality of columns with mutually parallel axes; the columns are perpendicular to a group of opposite sides of a combustion basin and fixedly connected with the side wall of the combustion basin; grate teeth of a rotating grate are correspondingly arranged at gaps between the adjacent columns of the fixed grate; fixing parts for connecting the rotating shaft are arranged at the middle parts of the lower sides of main bodies of the grate teeth; a rotating arm is arranged at one end of the rotating shaft and positioned at the exterior of the combustion basin; and the rotating arm is connected with a grate driving device. By using a grate assembly which combines the fixed grate and the rotating grate, dynamic combustion of a fuel in the combustion basin is ensured, and the disadvantages caused by a structure of an original cross-type rotating grate are overcome; structures of the grate teeth are simple and convenient to cast and mold; and meanwhile, heated surfaces of the grate teeth do not require alternately cooling and heating, so that no serious deformation is caused even in case of continuous combustion.

Description

technical field [0001] The invention relates to the technical field of heating and combustion equipment, in particular to an automatic biomass particle heating furnace. Background technique [0002] As the country pays more and more attention to environmental protection, and vigorously promotes the development and utilization of biomass energy. Make today's biomass pellet fuel widely used in actual production and life. Biomass pellet fuel has the advantages of easy storage, convenient transportation, clean environmental protection and high combustion efficiency, and is one of the main directions for the development and utilization of biomass energy. [0003] However, there are the following problems when using biological pellets as fuel: [0004] Problem 1: The biomass pellet fuel made of pressed plant stalks has high sugar content, and slagging often occurs in the furnace during combustion. When the fuel burns, slagging in the furnace will block the ventilation gap betwe...
