Grate Bars


Industrial furnace grate is one of the key components used in high-temperature industrial furnaces (such as blast furnaces, gas furnaces, electric furnaces, etc.). They are usually made of heat-resistant alloys, such as nickel-chromium alloy, chromium-aluminum alloy, etc., so that they can withstand high temperatures and corrosive environments.

The main function of industrial grate bars is to carry and support fuel or other heating media so that it is evenly distributed in the furnace and maintains stable combustion. Grate bars are usually flat plates with many small holes or slots to allow ventilation and waste removal. They can be customized in size, shape and structure according to specific furnace type and process requirements.

In addition, industrial grate bars also need to have good wear resistance, corrosion resistance and high temperature resistance to ensure long-term stable operation. Using high-quality industrial grate bars can increase the efficiency of your furnace, reduce energy consumption and extend its service life.
When it comes to industrial grates, there are some specific types and features worth noting:

Mesh grate bars: This type of grate bar consists of parallel steel wires or rectangular metal strips that form a mesh structure. They are commonly used in applications such as solid waste incinerators and fluidized bed furnaces to hold and burn solid fuels of different shapes and sizes.

Chain grate bars: This type of grate bar consists of chains connected together with flat metal bars fixed to the chains. Chain grate bars are usually suitable for furnaces with moving furnace bottoms, such as petroleum refineries and cement plants. They can transport materials, fuel or slag stably and achieve continuous combustion or treatment processes.

Tiltable grate bars: This type of grate bar is designed as a tiltable structure to control the flow and distribution of materials within the furnace. By adjusting the inclination angle of the grate bars, different heating and burning effects can be achieved. Tiltable grates are commonly found in processes such as coal gasifiers and coke ovens.

Rotary grate bars: This type of grate bar consists of a set of parallel rotating axes and connected transverse metal bars, and is used in equipment such as rotary kilns and rotary kilns. By rotating the grate bars, the material can be heated and processed evenly, and a continuous material flow can be achieved in the furnace.

The above are just some of the common types and features of industrial grates, there are many more different designs and applications. Specific selection and use should be based on specific industrial furnace equipment and process requirements to ensure the expected heating, combustion or processing effects.
