Combustion Chamber

Term from Heating industry explained for recruiters

A Combustion Chamber is a key part of heating systems where fuel (like gas or oil) burns to create heat. Think of it as the heart of a furnace or boiler where the actual heating happens. It's designed to contain the burning process safely and efficiently. When someone mentions this in their resume, they typically have experience working with furnaces, boilers, or industrial heating systems. Other common names for similar components include "burner box" or "firebox." Understanding this term is important because it's central to how heating systems work, and professionals who work with these need to know how to maintain, repair, or replace them safely.
