what is boiler chain grate?

A boiler chain grate is a moving, conveyor-belt-like metal floor inside an industrial furnace that feeds solid fuel, moves it through active combustion zones, and drops out the remaining ash. It is widely used for burning coal and biomass pellets in factories and power plants.

How It WorksFuel feed: Solid fuel drops from a storage hopper onto the front of the moving metal chain link belt.Combustion zones: The continuous loop carries the fuel slowly past a hot brick arch that dries and ignites it.Air control: Fans blow air up through tiny gaps in the moving metal grate bars to feed oxygen to the fire.Ash removal: Fully burned ash reaches the far end of the loop and falls off into a collection pit or conveyor.

Pros and ConsPros: Automatic feeding, steady steam production for factories, and lower equipment costs than gas or fluid-bed systems.Cons: Struggles with wet or low-quality fuels, creates higher emissions, and high heat can cause metal parts to wear out and break over time.

please let me know:Are you trying to repair or replace a chain grate part?What type of fuel (coal or biomass) are you burning?
