Reciprocating grates are generally divided into inclined reciprocating grates and horizontal reciprocating grates according to their structural form. Reciprocating grates are stepped and are composed of fixed grate plates and moving grate plates with the same arrangement stacked together. The moving grate reciprocates, causing the coal to move downwards evenly. The stroke is generally 70-110 mm, and a larger stroke is selected when the coal quality is poor.

  
When the coal layer moves on the moving grate, it is squeezed, rolled, and stirred. Part of the new coal is pushed onto the already burning hot coal layer below, while the moving grate plate returns, bringing part of the already burning hot coal particles back to the unburned new coal layer below, making the fuel layer have the characteristics of double-sided ignition, unlike the chain grate, there is relative movement between the coal layer and the grate, which can loosen the coal layer and increase its permeability. The mutual squeezing and friction between the coal particles also cause the ash shell wrapped around the hot coal particles to fall off, which is conducive to the burnout of coke. The reciprocating movement of the grate can also break the coke lumps with weak bonding strength, and has a certain fire-stirring effect.
