Hi-Flame Alpha 3 Boiler Inner Grate

Inner riddling grate (centre grate) for the Hi-Flame Alpha 3 Boiler (AL910). The inner grate sits at the centre of the grate assembly and is the component that rocks to break up and drop ash through to the ash pan below. It is a high-wear part on multi-fuel stoves and will eventually burn out or become too worn to riddle effectively.

A functioning inner grate is essential for coal and multi-fuel burning. It allows ash to fall clear of the burning fuel, maintaining airflow through the grate and keeping combustion efficient. When the bars burn thin or the riddling action stops working, the grate needs replacing to prevent the fire from becoming starved of air from below.
