Abstract
The invention relates to a boiler, namely a boiler with a steam cooling system for a fire grate. The boiler comprises a boiler body, wherein a hopper is arranged in front of the boiler body; the fire grate is arranged in the boiler body; a plurality of wind chambers are arranged under the fire grate; a steam pipe is arranged under the fire grate; a plurality of steam holes are formed in the steam pipe. A lot of experiments prove that after the fire grate is provided with the steam cooling system, the situations that fire grate segments are burnt out during the operation process are greatly reduced, and the service life of the fire grate segments is prolonged to a great extent; the situations that the fire grate segments are burnt out and penetrating shafts deform during shut-down of the boiler are reduced; fuel in the hopper can be effectively prevented from being ignited by spread of fire; reliable fundamental guarantee is provided for the safe and stable operation of the boiler.
Description
technical field
The present invention relates to a kind of boiler, i.e. a kind of boiler with fire grate steam cooling system.
Background technology
In the prior art, the design and fabrication of current boiler grate, great majority more pay attention to the stability that the reasonability of structural design and fire grate run, but lack and propose to explicitly call for the protection system of fire grate.In boiler running process, stoker surface temperature is very high, and wherein primary zone portion temperature is more than 800 DEG C.Fire grate runs under this worst hot case, is easy to the situation occurring scaling loss, and the probability add fire grate maintenance, changing, namely adds the maintenance cost of boiler.In furnace shutting down process, boiler bottom wind blower fan needs Close All, and stoker surface lacks effective cooling protection measure; stoker surface temperature is sharply raised; fire grate segment can be caused under serious conditions to burn, and fire grate wears the adverse consequences such as shaft distortion, and boiler cannot normally be run.On fire grate, fuel flame easily spreads and causes the fuel combustion of hopper place, jeopardizes hopper fuel.Therefore, boiler grate cooling system just seems particularly important.
Summary of the invention
The object of the invention is for above-mentioned deficiency and provide fire grate effective cooling, improving service life, a kind of boiler with fire grate steam cooling system of hopper use safety.
Technical solution of the present invention is: a kind of boiler with fire grate steam cooling system, comprises body of heater, have hopper before body of heater, have fire grate in body of heater, has multiple air compartment below fire grate.Below fire grate, set up steam pipe, steam pipe has several steam holes.
Or one or more steam pipe is set up in the middle of each air compartment of fire grate, every root steam pipe has some steam holes.
Or steam pipe (preventing hopper fuel from being burnt) is provided with below the fire grate of hopper and fire grate contact position, have some steam holes on every root steam pipe top.
Advantage of the present invention is: 1, experimental results demonstrate, after fire grate increases steam cooling system, the fire grate segment scaling loss situation occurred in running greatly reduces, and to a great extent, extends the service life of fire grate segment.The situation that the fire grate segment occurred in furnace shutting down process burns, wears shaft distortion have also been obtained great improvement.2, effectively prevent from hopper fuel from being spread to ignite.3, be safety, the stable operation of boiler, provide reliable basic guarantee.
Below in conjunction with accompanying drawing, embodiments of the present invention are described in further detail.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present invention.
Fig. 2 is Fig. 1 top view.
Detailed description of the invention
See Fig. 1,2, parts title is as follows: body of heater 1, hopper 2, fire grate 3, air compartment 4, steam pipe 5, face arch 6, rear arch 7, stove cylinder 8.
See Fig. 1,2, a kind of boiler with fire grate steam cooling system, comprises body of heater 1, and body of heater 1 has hopper 2 above, has fire grate 3 in body of heater 1, and fire grate 3 has multiple air compartment 4 below.Near each air compartment 4 of fire grate 3, press close to fire grate 3 bottom surface and to set up in the steam pipe 5(figure at many intervals five), have some steam holes on every root steam pipe 5 top.Pressurized vapor directly can be blown to fire grate 3 surface, reach the object reducing fire grate 3 surface temperature, protection fire grate 3.And according to the different running statuses of boiler, the aperture of mounted valve on every root steam pipe 5 can be adjusted, the chilling temperature on adjustment fire grate 3 surface in real time.
Be provided with steam pipe 5 below hopper 2 and the fire grate of fire grate 3 contact position, have some steam holes on every root steam pipe 5 top.
Be applicable to chain or reciprocating-grate boiler.The quantity of steam pipe 5 comprises one or more.Steam pipe 5 mounting means is not limited to stretch into from fire grate side.Steam pipe 5 position is not limited to by air compartment.Steam pipe 5 position of opening is not limited to top.
Describe above, just the specific embodiment of the present invention, various illustrating is not construed as limiting flesh and blood of the present invention.
