Chain Grate: Reliable Travelling Chain Grate for Biomass & Coal-Fired Boilers

The travelling chain grate, also known as chain grate, serves as the key combustion equipment for solid-fuel industrial boilers. It is extensively matched with coal-fired boilers, biomass boilers, waste heat boilers and thermal fluid heaters, and is favored by boiler manufacturers, power plants, heating stations and industrial thermal enterprises worldwide.

Different from fixed grates and reciprocating grates, the chain grate works as an integrated moving combustion platform. Driven by reducer and sprocket, the whole grate assembly runs slowly and stably. Solid fuel is fed onto the front section of the chain grate, moves forward with the grate, and completes ignition, combustion and burnout sequentially in the furnace. Ash residues are discharged at the tail end automatically. This continuous feeding and combustion mode greatly simplifies boiler operation and reduces manual stoking work.

Material selection directly decides the service life of boiler chain grate. Our chain grate and grate bars are made of high heat-resistant cast alloy. The material keeps stable mechanical strength under long-time high temperature, oxidation and thermal shock. It effectively prevents grate bar deformation, cracking and burning loss, even when burning aggressive fuels such as straw, rice husk, wood chips, palm kernel shell and mixed biomass. Reasonable gap design ensures sufficient air distribution, makes fuel burn fully, lowers carbon content in slag and lifts boiler thermal efficiency.

Our full set chain grate system contains grate bars, drive chains, link plates, rollers, grate pins, side seals, tensioning devices and transmission components. We can produce chain grates matching SHL, SZL and other popular boiler models, and accept non-standard customization according to boiler capacity, furnace width, fuel type and local working conditions. Whether customers need a brand-new complete chain grate assembly or separate replacement boiler spare parts for maintenance, we can provide accurate drawing and suitable solutions.

Stable running and easy maintenance are outstanding advantages of our travelling chain grate. The modular structure allows quick replacement of damaged grate bars without dismantling the whole set. Optimized tension adjustment structure reduces chain deviation and jamming failure, lowering long-term operation and maintenance cost for end users. Strict quality inspection is carried out for each component before delivery, including dimension checking, material testing and assembly running test.
