The travelling chain grate is a core combustion component widely used in industrial coal-fired and biomass boilers. It continuously transports fuel into the furnace while supporting uniform combustion, reducing coking and improving thermal efficiency. Our heavy-duty chain grate adopts high-temperature resistant alloy materials, precise assembly structure and stable transmission design. It is suitable for burning coal, wood chips, straw, palm kernel shell and other solid fuels. We provide complete chain grate sets and replacement spare parts including grate bars, chains, rollers and pin shafts for WNS, SHL and other boiler models, supporting customized sizes for global boiler projects.

A chain grate is a commonly used stoker grate in industrial boilers. The main structural difference between it and a belt-type grate lies in the adoption of multiple rigid crossbeams. The grate bars are installed in the corresponding clamping grooves of the crossbeams, which are fixed on the driving

Cast Iron Economizers vs. Steel Tube Economizers: Key DifferencesEconomizers are vital for boiler energy efficiency, recovering flue gas waste heat to preheat feedwater. Cast iron and steel tube economizers differ significantly in design, performance, and use—here’s a concise breakdown.1. Basic Defi
