Large scale chain grate grate is a kind of mechanized layer burning equipment, which is used for chain grate boiler with evaporation amount of 10 to 40t/h. It is used for automatic coal dropping with pulverized coal hopper. It can also be used as a wind puler or a mechanized semi suspended combustion machine. It can also be used for a variety of heating and drying. In 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.
The furnace chain is made up of stoves, splints (left, right and middle three), chains, studs, lining pipes and rollers. The five 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 is equipped with a driven shaft to turn the grate. A number of separate independent wind chambers are arranged in the longitudinal direction of the grate. The first wind from both sides of the grate or the air duct into the wind chamber reduces the speed and can be filled with the wind chamber evenly. The intake volume of each air chamber can be regulated by a wind regulating device. The grate air chamber is arranged with ash setting device. At the bottom of the wind room, a fixed landing floor with a falling ash is arranged at the bottom of the wind chamber, and the moving ash door connected to the pull rod is usually sealed by the falling ash gate, and the ash door handle is pushed and pulled regularly. The dust in the air chamber falls from the falling ash to the chain of the lower furnace. With the chain of the furnace chain to the front part, the ash can also be transported to the grate front end of the ash bucket or grill door attached. Near, it is taken out by an artificial grilled machine. A contact side seal structure is adopted between the sides of the grate and the bracket to prevent the coal blocks leaking into both sides of the grate and prevent the leakage of 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. The grate has a compact structure, stable and reliable operation, convenient installation and maintenance, convenient to disassemble and disassemble grate flake, and do not pull the long pin of the furnace. The ventilation cross section ratio of the grate surface is about 7%, the amount of coal leakage is less, the grate piece is durable, the ventilation is uniform, and the combustion operation is stable.
