Heavy scale chain grate grate is a mechanized layer burning equipment, which is used for chain grate boiler with evaporating amount of 20 to 130t/h. It is used for automatic coal dropping with pulverized coal hopper. It can also be used as a mechanized semi suspended burning fire bed, and can be used for a variety of heating and baking. In the special equipment. It is suitable for burning bituminous coal, lignite and peat. Specially designed, it can also be used as a combustion equipment with bagasse, firewood and rice husk as fuel.

Technical features：

The furnace chain is made up of stoves, splints (left, right and middle three), chains, studs, lining pipes and rollers. The seven sections of the stove bar are arranged on the two sides of the conical shaft platform, and are inserted into the holes of the two pieces of splint, and the front and rear bars are folded into scales, and the coal leakage is very small. The front shaft of the grate is in front, and the furnace is moved and transferred. The rear rail is fitted with a rear guide to make the grate turn.

A storehouse is arranged longitudinally along the grate, and the primary air entering the air chamber by both sides of the grate is reduced by the speed of "diffusion", and can be uniformly filled with the air chamber. The intake volume of each air chamber can be adjusted by adjusting the angle of the wind stroke plate of the wind scoop. The end of the furnace is arranged with ash setting device. At the bottom of the wind room, the fixed landing dust floor with the falling ash mouth is arranged, and the moving ash door connected to the pull rod is usually sealed with the falling ash gate, and the ash door handle is pushed and pulled regularly. The dust in the wind chamber falls from the falling ash to the chain of the lower furnace, and as the furnace chain moves on the lower guide, the ash falls into the arch of the ash bucket. The unique side seal structure between the sides of the grate and the bracket prevents the coal from leaking into both sides of the grate and prevents air leakage on the side of the grate. The slag stopper is placed on the shelving behind the driven shaft. The slag stopper is pressed on the grate by its own weight. Its main function is to shovel ash and prevent ash from falling into the grate. Secondly, it increases the burning time of the combustibles in the grate and burns out the burning time of the ash in the ash. This grate has compact structure, stable and reliable operation, convenient installation and maintenance, convenient to disassemble and disassemble grate, and do not have to loose the long pin of the furnace. And under the condition of non stop furnace, the full side air supply mode of the main combustion area has the advantages of uniform lateral air distribution, good air tightness in inner air chamber and high air retention rate. There are two ash doors in the rear part of the air chamber bottom plate, and a small amount of ash can be removed during maintenance. With less coal leakage, the grate slice is durable, the ventilation is uniform, and the combustion operation is relatively stable.

The technical parameters of double scale heavy scale chain grate can also be made according to user requirements.
