The cross beam chain grate can be used for 20 ~ 200t/h boiler. The fuel can be bituminous coal, anthracite, lignite and peat. Specially designed, it can also be used as a combustion equipment with bagasse, firewood and rice husk as fuel.
The cross beam chain grate is a mechanized, sophisticated structure and advanced technology. The utility model can be widely used as a combustion device for large scale burning boiler cross beam chain grate chain by chain link, guide wheel, roller, washer, chain shaft and pin assembly.
The chain moves regularly on a special track. The sprocket wheel with the track on the driving shaft successively moves the side rollers on the chain to push the chain forward. The grate movement is all rolling friction. The required motion is small. The adjacent chain is joined by the two link of the same section through the T angle steel crossbeam. The T type angle steel crossbeam is embedded with grate slice with T groove, so it is called cross beam chain grate. The rigidity of the beam of T angle steel is high. The processing precision of the chain is high, so the width of the crossbeam grate can be wide according to the needs of the boiler capacity; and because the grate is embedded in the T type angle steel beam, the grate is not easy to fall off when the grate runs, so the grate is running reliably. All castings of crossbeam grates are qualified by advanced physical and chemical tests and spectroscopic tests. The chain block of the grate transmission part is produced by automation special production equipment. The method of fixed point quantitative air supply can be adopted in furnace arrangement, and the non-uniform coefficient of transverse air distribution is less than 10%. The front axle of the grate adopts thrust bearing anti deviation and anti channelling technology and the lower rail adopts anti deviation technology.
Product manufacture and acceptance comply with JB3271 standard
The technical parameters of cross beam chain grate can also be made according to user requirements.
