What sort of adj. were needed as in more or less draft, has the time between shakes changed at all, do you notice a difference in weight of the full ash pan, any details about the change over one should look fer
Less air going into the stove on the hand fed. I'm running it now at 1 turn open most of the time, JC gave me a probe thermometer to replace the surface mount on the stack before the baro. The stack temp. is running around 650 now. When the weather gets warmer I'll reduce the air more, down to 1/2. With the previous coal for the same burn temperature I'd need 1 1/2 to 2 1/2 turns open.
Also, the performance of the stove tended to decline after the first few days of burning, starting with an empty stove. After about a week or two it would be burning so poorly that in the morning or upon arriving home I'd end up dumping the fire and starting over. No such problem now, the fire is just as good today as it was Monday, once I got the baro set up correctly. Draft running -.045 to -.05" WC now.
I am getting more heat from each load of coal I place in the stove, it burns longer and completely. So I'm using less coal and the result is less ash.
The stoker is less fussy, but the ash doesn't have any unburnt pieces in it, as it did before. I've been able to reduce the burn rate, therefore less ash as well as less coal used.
All in all, a major improvement. I did have a slight problem in the Harman with clinker formation, but I was burning the stove too hot at first, that has become a non-issue since.
