A grate (or fire grate) is a frame, usually of iron bars, to retain fuel for a fire. Heavy metal firebacks are sometimes used to capture and re-radiate heat, to protect the back of the fireplace, and as decoration.

This tubular fireplace grate heater has a large surface area heat exchanger in a compact design, with a fan or blower (fans and blowers are not the same) to multiply the effect of natural convection. This is a very basic tubular blower that sits under a grate and heats the air being pumped through it from the heat of the coals.
The primary functions of a fireback are to protect the wall at the back of the fireplace and radiate heat from the fire into the room. The protection was especially important where the wall was constructed of insubstantial material such as daub (a mud and straw mixture coating interwoven wooden wattles), brick or soft stone.
Some fireboxes were equipped with a so-called combustion chamber, this is a distinct component from the firebox and tubes - a large single extension of the firebox space, into the boiler barrel, and above the brick arch and separated from the grate and the fire bed, this placed additional space between the fire and the rear fire tube/flue sheet.
