Abstract
The present invention mainly discloses a boiler component, i.e. a water-cooled horizontal reciprocating grate. It consists of position-fixed story grate and moving grate, in which the bottom portion of the position-fixed story grate is equipped with heat-absorbing tubes which are uniformly arranged and connected with the interior of the boiler, and the bottom portion of the moving grate is equipped with reinforcing ribs made up in the form of radiating rib. Said invented grate features long service life and high ehat efficiency.
Description
The present invention relates generally to the used fire grate of the reciprocal boiler of a kind of level, especially a kind of water-cooling type horizontal reciprocating furnace grate.
In background technology, horizontal reciprocating furnace grate comprises tilting location fire grate and moving grate.The location fire grate maintains static, and the moving grate root rotates around the fire grate axle, and can move back and forth along level, and its weak point is that fire grate segment burns out easily because of overheated, and service life is short, and maintenance load is big, often causes blowing out, influences heat supply and production.
Main purpose of the present invention provides a kind of fire grate burning that alleviates, the water-cooling type horizontal reciprocating furnace grate that increases the service life.
Major technique solution of the present invention is achieved in that water-cooling type horizontal reciprocating furnace grate comprises tilting location fire grate and moving grate.Location fire grate root is rotatable around the fire grate axle, but can not move, fire grate axle female pipe that instead supplies water.Fire grate bottom, location is placed with endothermic tube, and the position bottom transverse was equipped with the female pipe of the heat absorption that communicates with each endothermic tube on the location fire grate tilted.The fire grate axle is used the female pipe of the water supply that communicates with endothermic tube instead, and female pipe that supplies water communicates with boiler header by water inlet pipe, and female pipe that absorbs heat communicates by in outlet pipe and the boiler.Supplying water communicates in the female pipe of female pipe, endothermic tube, heat absorption and the boiler forms the boiler water cycle loop, carries out water-cooled and reaches the purpose that prevents the fire grate burning locating stoker surface thereby utilize boiler water to circulate to reach.
For preventing the moving grate burning, the reinforcement that changes the bottom of moving grate in the past is the thin and many muscle shape of fin form, is beneficial to its heat radiation.
Major advantage of the present invention and good effect are: improved fire grate service life 1..Utilize boiler water to form circulation the location fire grate is carried out water-cooled, reduce its surface temperature, alleviate and be subjected to the burning degree, improved service life.Moving grate is adopted the heat radiation type reinforcement, be beneficial to himself heat radiation, alleviate burning, improve service life.2. improved boiler thermal output.Boiler water improves water temperature through endothermic tube and returns in the boiler, has played the effect of raising boiler hot effect.3. reduce the blowing out maintenance, guarantee heat supply and production continuously.
Below in conjunction with accompanying drawing the invention process is described in further detail:
Fig. 1 is the water-cooling type horizontal reciprocating furnace grate structure diagram.
Referring to Fig. 1, water-cooling type horizontal reciprocating furnace grate is made of the location fire grate 1 and the moving grate 2 of many rows space.Location fire grate 1 can be managed 3 rotations of rising and falling around the water supply that plays the effect of fire grate axle is female.Endothermic tube 4 is fixed on fire grate 1 bottom, location, each corresponding endothermic tube 4 in fire grate 1 bottom, location, and two ends communicate with the female pipe 5 of heat absorption that supply water female pipe 3 and transverse horizontal are arranged respectively.Water inlet pipe 6 communicates with supply water female pipe 3 and boiler header respectively, outlet pipe 7 respectively with female pipe 5 of heat absorption and boiler in the female pipe of heat absorption 5 the characteristics horizontal positioned that communicate according to horizontal fire grate, adopt riffled tube or take corresponding measure, overcome the boiling of inner tube layer stream.
Moving grate 2 can be around fire grate axle 8 rotation of rising and falling, but along continuous straight runs moves back and forth simultaneously.The reinforcement 9 of moving grate 2 bottom surfaces is made the thin and many muscle shape of fin form; moving grate 2 two ends are contacted with location fire grate 1 all the time; when the heat that itself is absorbed conducts to location fire grate 1 and endothermic tube 4 effectively; again after-heat is radiate by radiating ribs, protect and avoided the fire grate scaling loss.
