KA are of a different stoker design than your KAA...only thing the same is that both are Keystokers.oliver power wrote: ↑Tue. Jul. 24, 2018 1:15 amMy Kaa-2 has 3 grates.... Of course, the physical size of your boiler is way too big to be a Kaa-2.
Actually, all the KA (3), KB (4), KC (5), KD (6), KE (7), KF (8), and the KG (9) (@ 528,000 BTU) are of the same design and grate (numbers) go up accordingly and are all inclined flat-bed stokers. Whereas, KAA are just flat-bed and not inclined and max out @ 85,000 BTU.
