Meaning and Definition
A mechanical stoker system for solid fuel (especially coal) in furnaces or boilers, consisting of a continuously moving chain of metal plates or links that transports the fuel through the combustion zone.
Any linked series of components that forms a bed or moving platform for combustion or material processing; by extension, can metaphorically refer to a rigid, interlinked series of events or obligations that is difficult to escape.
Dialectal Variation
British vs American Usage
Differences
No significant lexical difference; the technical term is identical. Contextual use is primarily in industrial, power generation, and historical engineering texts in both varieties.
Connotations
In both varieties, the term carries connotations of heavy industry, older power stations, steam generation, and mechanical engineering.
Frequency
Equally rare and specialised in both BrE and AmE. Its usage has declined with the move away from coal-fired systems.

FAQ
Frequently Asked Questions
No. While both convey materials, a chain grate is specifically a series of interlinked metal plates forming a solid, heat-resistant bed for combustion within a furnace. A conveyor belt is typically a rubber or fabric belt for general transport.
Rarely and only in highly technical jargon, meaning 'to process or feed via a chain grate'. In standard English, it is almost exclusively a compound noun.
Its relevance is historical and specialised. While some older or specific industrial plants still use them, modern coal power often uses pulverised fuel or fluidized beds. The term remains important in engineering history, maintenance, and some industrial contexts.
The chain provides the motive force, allowing the entire grate surface (the bed of linked plates) to move continuously, transporting fresh fuel into the fire and ash out of the combustion zone.
