Now that I am in summer mode with our KA2 I am trying something different.
I am "dialing" down the feed rate a bit at a time. I have already backed it off 3 complete turns. Don't think I have ever done the in the past but might as well save some coal!

You are feeding less coal per stroke, but are you feeding less per day?

My EFM burns the same amount per day with any feed rate less than 10 lbs/hr of run time. The standby losses of the boiler drive most of the consumption.

Be careful,,,,

Lowering the feed rate does not mean the boiler will use less coal. If you run the feed rate to low, it can actually use more coal because the stoker will have to play "catch-up" when there is a heat call.

Good luck!
