Abstract
The invention discloses a boiler grate which belongs to the technical field of boilers. The boiler grate comprises a grate plate which is provided with an upper plate and side plates enclosed at the lower end of the upper plate, and a through hole which is small on the top and large at the bottom is vertically formed in the upper plate. The aperture ratio of the upper plate is 3.1%. Due to the fact that the through hole which is small on the top and large at the bottom is formed in the grate, both air supply and sand leakage can be taken into account during burning of bagasse. Therefore, the sediment can be leaked and removed in time without blocking the through hole of the grate, and the normal work of a boiler can be ensured. The boiler grate not only reasonably utilizes the natural resource of bagasse as the fuel of the boiler, but also improves the economy and reliability of the boiler.
Description
Technical field
The present invention relates to boiler technology field, especially a kind of boiler grate using bagasse as fuel wood.
Background technology
Boiler is a kind of energy conversion; There is to boiler input the fuel of heat energy, through boiler conversion, outwards export steam, high-temperature water or the organic heat carrier with certain heat energy and produce and living needs for people.Its fuel mainly coal, the flue gas dust concentration of not only discharging as fuel with coal is high, and flue gas blackness is large, causes severe contamination to environment, and along with the minimizing day by day of coal resource, causes production cost more and more higher; Wide cane planting ground is had in China, squeeze the bagasse after sugar, can as the fuel of boiler, but because bagasse itself carries silt when getting back from ground, boiler grate hole plug can be made during burning, fire grate hole plug gas does not circulate and will cause the increase of pot furnace pressure, finally cause the blast of boiler, so how to transform boiler pot row, namely the bagasse of Appropriate application natural resources is as the fuel of boiler, can improve again economy and the reliability of boiler, be people's new problems anxious to be resolved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of boiler grate, and this boiler grate can solve the fire grate hole plug of boiler grate, causes the bursting of boilers, causes the problem of personal injury and device damage.
In order to solve the problem, the technical solution adopted in the present invention is: this boiler grate, includes fire grate segment, the side plate that described fire grate segment has upper plate and mutually encloses in upper plate lower end, on described upper plate, homogeneous vertical offers up-small and down-big through hole, and the percent opening of described upper plate is 3.1%.
In the technical scheme of above-mentioned boiler grate, technical scheme can also be more specifically: described through hole is round tube hole, and the upper-end inner diameter of described through hole is 14mm, and described through hole bottom diameter is 16mm.
Further: described upper plate center offers the through hole installing fixture, the length of described upper plate is 310mm, and width is 298mm, and thickness is 20mm.
Further: described upper plate is square or rectangular.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the bagasse of the present invention's both Appropriate application natural resources is as the fuel of boiler, can improve again economy and the reliability of boiler.
2, the through hole on fire grate segment of the present invention, in the process of bagasse burning, air feed and leakage sand are taken into account, and are leaked by silt in time and remove, do not block fire grate through hole, ensure that the normal work of boiler.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is that Figure 1A-A locates sectional view.
Fig. 3 is Fig. 2 B-B place sectional view.
Fig. 4 is I place's enlarged drawing in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Embodiment one
A kind of boiler grate, include fire grate segment, the fire grate segment shown in Fig. 1, Fig. 2, Fig. 3 has upper plate 1 and mutually encloses the side plate 2 in upper plate lower end, and upper plate 1 is rectangle, and the length of upper plate 1 is 310mm, and width is 298mm, and thickness is 20mm; Upper plate 1 vertically offers up-small and down-big through hole 1-1, the percent opening of upper plate is 3.1%; Through hole 1-1 is round tube hole and is uniformly distributed on upper plate, and the upper-end inner diameter of through hole 1-1 is 14mm, and through hole 1-1 bottom diameter is 16mm; Upper plate 1 center also offers and installs the through hole 1-2 that fixture is the screw thread of bolt.
Embodiment two
Upper plate 1 is square; The length of side is 310 mm, and all the other are all identical with embodiment one.
Fire grate segment of the present invention offers up-small and down-big through hole, and in the process of bagasse burning, air feed and leakage sand are taken into account, and are leaked by silt in time and remove, do not block fire grate through hole, ensure that the normal work of boiler.Both the bagasse of Appropriate application natural resources was as the fuel of boiler, can improve again economy and the reliability of boiler.
