Abstract
The present invention relates to boiler technology field, a kind of boiler grate is provided, including fire bars and water cooling tube, the water cooling tube is made up of the connection of several U-tubes, the water cooling tube both ends are respectively arranged with water inlet end and water side, and uniformly solid welding has some fire bars in the side wall of the vertical portion of the U-tube, and the projection of cylinder is both provided with any one fire bars, the height of projection, ventilation groove is provided with the projection.The beneficial effects of the invention are as follows water cooling tube is set, the heat of fire grate can be for delivery to water-cooled cooling be carried out to fire grate while in boiler water cycle, reducing thermal waste, fire grate does not allow yielding and damage, service life length；In addition, being provided with the projection that height does not wait on fire bars, there is ventilation groove on projection, can causing big briquette fuel, vacantly burning is without tightly packed, and air permeability is good, and efficiency of combustion is higher.
Description
Technical field
The present invention relates to boiler technology field, more particularly, to a kind of boiler grate.
Background technology
Boiler has the forms such as chemical energy, electric energy into boiler input energy, and pass through pot as a kind of energy conversion
The conversion of stove, outwards output have steam, high-temperature water or the organic heat carrier of certain heat energy.Fire grate is that solid combustion is banked up in boiler
To expect and be effective the part of burning, fire grate is often manufactured with cast iron, ensures necessary ventilation gaps between being flaked a fish after assembling, and
And the draft chamber that can adjust air quantity is set below in fire grate toward contact, so that air passes through gap incoming fuel layer.Common
Fire grate does not have refrigerating function typically, for a long time at high temperature after use, is easily burnt deformation, it is necessary to often change and tie up
Repair.
The content of the invention
It is an object of the invention to provide a kind of boiler grate, service life length.
The technical scheme is that：A kind of boiler grate, including fire bars and water cooling tube, the water cooling tube is by several U
Type pipe connection composition, the water cooling tube both ends are respectively arranged with water inlet end and water side, the side wall of the vertical portion of the U-tube
Upper uniform solid welding has some fire bars, is both provided with the projection of cylinder on any one fire bars, the height of projection,
Ventilation groove is provided with the projection.
Further, the material of the fire bars is cast steel, and the material of the water cooling tube is steel part.
The present invention has the advantages and positive effects of：By the water inlet end of water cooling tube and the water side header with boiler respectively
Connection, the heat of fire grate can carry out water-cooled cooling, stove for delivery to while in boiler water cycle, reducing thermal waste to fire grate
Row does not allow yielding and damage, service life length；In addition, being provided with the projection that height does not wait on fire bars, there is air duct on projection
Groove, can causing big briquette fuel, vacantly burning is without tightly packed, and air permeability is good, and efficiency of combustion is higher.
Brief description of the drawings

7th, ventilation groove
Embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
As Figure 1-Figure 2, a kind of boiler grate of the present invention, including fire bars 1 and water cooling tube 2, the water cooling tube 2 is by some
The individual connection of U-tube 3 composition, the both ends of water cooling tube 2 are respectively arranged with water inlet end 4 and water side 5, the vertical portion of the U-tube 3
Uniformly solid welding has some fire bars 1 in the side wall divided, and the projection 6 of cylinder, projection are both provided with any one fire bars 1
6 height, is provided with ventilation groove 7 on the projection 6, and the material of the fire bars 1 is cast steel, the material of the water cooling tube 2
Matter is steel part.
The course of work of this example：The water inlet end of water cooling tube 2 and water side are connected with the header of boiler respectively, fire grate
Heat can carry out water-cooled cooling for delivery to while in boiler water cycle, reducing thermal waste to fire grate, and fire grate does not allow mutability
Shape and damage, service life length；In addition, being provided with the projection 6 that height does not wait on fire bars 1, there is ventilation groove 7 on projection 6, can be with
So that vacantly burning is without tightly packed for big briquette fuel, air permeability is good, and efficiency of combustion is higher.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be considered as the practical range for limiting the present invention.All equivalent changes made according to the present patent application scope and improvement
Deng, all should still belong to the present invention patent covering scope within.
Claims (2)
1. boiler grate, it is characterised in that：Including fire bars and water cooling tube, the water cooling tube is made up of the connection of several U-tubes, institute
