Stokers With Push Feeds, Feed Adjustment

2001Sierra · Post by **2001Sierra** » Sat. Jan. 04, 2014 5:31 pm

Year 4 with Keystoker 90 controlled with a Coal-trol. Really cold weather now and I found it necessary to turn the feed adjustment clockwise one turn. My question is do others have one adjustment for fall, and spring, and another setting for winter? A guy I work with has Harman Magnum and he has to adjust his for spring and fall, mainly for maintenance mode, he is not running a Coal-trol.

Why not just leave it set the way you have it now? As long as you don't have any overheating issues in mild weather, I would just leave it at the current setting.

Once I got the feed screw set to have about 1" of ash at full burn when I first started up a couple years ago I have not changed it. I also leave the restrictor plate on the combustion fan in the same place all the time. The only thing I have changed occasionally is the timer settings. During shoulder months I have them set at 3 minutes on, 14 minutes off with distribution blower on for 8 minutes. During the colder months they are set to 4 minutes on, 12 minutes off with distribution blower on all the time.

I do check to see if feed settings need adjustment after each new load of coal I get into but I have been getting rice from the same supplier and it is very consistent.

In the Manual for coaltrol, I think you should set the feed rate screw to MAX and then adjust the MIN/MAX on the coaltrol to keep it idling and not to push hot coals off the end.

I don't have a coaltrol on my Keystoker, but I have the screw adjusted at max burn, so it's not pushing hot coals off the end. I think It's about 2 or 3 turns out, can't remember. usually dont' adjust it once I set it.

This is correct. The nominal settings for MIN/MAX from the factory for a Keystoker 90, 105 or Koker are 10 and 85 respectively. It may be possible to increase your MAX setting up to 99. Just make sure that you have about an inch of ash at the end of the grate. See "MIN/MAX Adjustment" heading in the booklet for a procedure to do this. This is found on page 12 in version V3 or V4 booklets.

Thanks WNY.
