The small scale chain grate is an efficient and multifunctional staged combustion device.

In energy utilization and industrial production, the grate, as an important component of combustion equipment, directly affects the operational efficiency of the entire system. The small scale chain grate, as a mechanized layer combustion device, has gradually occupied a place in the market due to its unique technical characteristics and wide range of applications.

The small scale chain grate, as the name suggests, has a grate plate design that resembles scales. This design not only allows the ventilation cross-section of the grate to reach 8%, ensuring uniform ventilation and stable combustion, but also significantly reduces coal leakage, improving combustion efficiency. In addition, the grate plates are connected in a chain-like manner through sleeves or drums, making the grate more stable and reliable during operation.

Structurally, the small scale chain grate consists of an active shaft, a driven shaft, brackets, ash discharge devices, air adjustment devices, furnace chains, coal hoppers, front wind doors, and side seals. The furnace chain is made up of furnace bars, clamps, chains, double-headed bolts, liners, and rollers. The furnace bars are grouped in sets of five, inserted into the holes of the clamps, and overlap in a fish scale pattern, allowing the grate plates to self-clean ash and coal debris during operation, reducing maintenance workload.

In terms of application range and requirements, the small scale chain grate can be matched with boilers with an evaporation capacity of 2-40t/h and can also be used in various heating and drying equipment. It is suitable for burning bituminous coal, lignite, and peat, and can also be specially designed to serve as combustion equipment using raw materials such as bagasse, wood, and rice husks. This type of grate has a wide range of applications and can meet the energy needs of different fields and industries.

In addition, the small scale chain grate also has advantages such as easy installation, stable and reliable operation, and convenient maintenance. During installation, there is no need to install lower guide rails or conduct underground civil engineering; a concrete platform can be made on-site for the user. This installation method greatly simplifies the installation process and reduces installation costs. At the same time, the loading and unloading of the grate plates are also very convenient, allowing for replacement without shutting down the furnace, ensuring continuous and stable operation of the equipment.

In terms of Applications, the small scale chain grate is widely used in the heat treatment processes of industries such as steel, aluminum alloy, and ceramics. In the steel industry, it can be used in processes such as casting, ingot casting, forging, and quenching, improving product quality and energy saving; it also plays an important role in the aluminum alloy industry; in the ceramics industry, its efficient combustion performance has also been widely applied.

In summary, the small scale chain grate plays an important role in energy utilization and industrial production with its high efficiency, stability, and multifunctional characteristics. With continuous technological advancements and an expanding market, it is believed that the small scale chain grate will see broader applications and development in the future.
