The reciprocating type is composed of a set of fixed grate pieces and a group of reciprocating movable grate pieces, Boiler Grate which are divided into two types: stepped type and horizontal type. The reciprocating motion of the movable grate piece gradually pushes the coal seam to the rear for combustion, Boiler Grate so this grate has a wide adaptability to coal types.
Vibration type: There is a small inclination angle between the grate surface and the horizontal plane, Boiler Grate and the grate piece uses the motor and the eccentric to generate regular vibration. When vibrating, Boiler Grate the fuel layer continuously moves to the rear of the furnace, so that the burned ash falls into the ash pit at the end of the grate. This grate is characterized by its simple structure. Lower feeding type: a trough-shaped grate with a screw rod at the bottom of the trough, Boiler Grate which leads to the coal hopper outside the furnace. The coal is fed into the coal trough through the screw rod from the lower part of the coal hopper, from bottom to top, into the combustion high temperature zone, Boiler Grate when the ash exceeds the accumulation angle, it is discharged to both sides by gravity. This kind of grate has a simple structure, but has certain requirements on the particle size and humidity of the coal, Boiler Grate and is generally only suitable for small industrial boilers with an evaporation capacity of less than 1 ton/hour.
The reciprocating type is a small mechanized grate developed on the basis of a fixed stepped grate. It has the characteristics of simple structure, convenient manufacturing, Boiler Grate low metal consumption and good smoke and dust removal effect. It is widely used in small industrial boilers and is a kind of combustion equipment with development prospects. The structure of the reciprocating grate: inclined reciprocating grate, Boiler Grate horizontal reciprocating grate and strip reciprocating grate.
