Abstract
The utility model relates to the field of boiler technology, a boiler fire grate is provided, including fire bars and water -cooled tube, the water -cooled tube comprises a plurality of U type union coupling, the water -cooled tube both ends are provided with into water end and play water end (W. E. ) respectively, evenly weld a plurality of piece intrinsic fire barss on the vertical partial lateral wall of U type pipe, all be provided with the columniform projection on the arbitrary fire bars, highly the varying of projection, be provided with the air conduits groove on the projection. The beneficial effects of the utility model are that setting up the water -cooled tube, during the heat of grate can transmit the feed water circulation, reducing heat energy and carry out the water -cooling cooling to the grate extravagant the time, the grate is difficult to be out of shape and damage long service life, in addition, be provided with highly unequal projection on the fire bars, have the air conduits groove on the projection, can be so that the unsettled burning of bold fuel and the clearance leakage is piled up, the air permeability is good, and combustion efficiency is higher.
Description
Technical field
The utility model is related to boiler technology field, especially relates to a kind of boiler grate.
Background technology
Boiler, as a kind of energy conversion, has the forms such as chemical energy, electric energy in boiler input energy, and passes through pot
The conversion of stove, outwards output has steam, high-temperature water or the organic heat carrier of certain heat energy.Fire grate is solid combustion of banking up in boiler
Expect and be effective the part of burning, fire grate commonly uses cast iron manufacture, ensures necessary ventilation gaps between flaking a fish after assembling, and
And in fire grate, the draft chamber that can adjust air quantity is set below toward contact, so that air passes through gap incoming fuel layer.Common
Fire grate does not typically have refrigerating function, after using at high temperature for a long time, is easily burnt deformation, needs often to change and tie up
Repair.
Content of the invention
The purpose of this utility model is to provide a kind of boiler grate, long service life.
The technical solution of the utility model is: a kind of boiler grate, and including fire bars and water cooling tube, described water cooling tube is by some
Individual u-shaped pipe connects composition, and described water cooling tube two ends are respectively arranged with water inlet end and water side, the vertical portion of described u-shaped pipe
On the wall of side, uniform solid welding has some fire bars, and described any one fire bars is both provided with the projection of cylinder, the height of projection
, described projection is provided with ventilation groove.
Further, the material of described fire bars is cast steel, and the material of described water cooling tube is steel part.
The utility model has the advantages and positive effects that: by the water inlet end of water cooling tube and water side respectively with boiler
Header connects, and the heat of fire grate can carry out water-cooled fall to fire grate for delivery in boiler water cycle while reducing thermal waste
Temperature, fire grate is not allowed yielding and is damaged, long service life；Additionally, the projection that height does not wait is provided with fire bars, projection have logical
Wind groove so that the hanging burning of big briquette fuel and not tightly packed, air permeability is good, and efficiency of combustion is higher.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model.
In figure:
1st, fire bars 2, water cooling tube 3, u-shaped pipe
4th, water inlet end 5, water side 6, projection
7th, ventilation groove
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is elaborated.
As Figure 1-Figure 2, a kind of boiler grate of the utility model, including fire bars 1 and water cooling tube 2, described water cooling tube 2 by
Several u-shaped pipes 3 connect composition, and described water cooling tube 2 two ends are respectively arranged with water inlet end 4 and water side 5, described u-shaped pipe 3 perpendicular
On the side wall of straight part, uniformly solid welding has some fire bars 1, and described any one fire bars 1 is both provided with the projection 6 of cylinder,
The height of projection 6, described projection 6 is provided with ventilation groove 7, the material of described fire bars 1 is cast steel, described water cooling tube 2
Material be 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 to fire grate while reducing thermal waste, fire grate does not allow mutability for delivery in boiler water cycle
Shape and damage, long service life；Additionally, the projection 6 that height does not wait is provided with fire bars 1, projection 6 has ventilation groove 7, permissible
So that the hanging burning of big briquette fuel and not tightly packed, air permeability is good, and efficiency of combustion is higher.
Above an embodiment of the present utility model is described in detail, but described content is only of the present utility model
Preferred embodiment is it is impossible to be considered for limiting practical range of the present utility model.All made according to the utility model application range
Impartial change and improvement etc., all should still belong within patent covering scope of the present utility model.
