I thought you took that fan off with the restrictor. What fan do you have on there.

Only 4" tall with the fan wide open.... that can't be how it is supposed to burn! What is the cfm of that combustion fan? (sorry if it is further back in the thread somewhere) I would expect the flames to be hitting the top of the fire box with the fan wide open.

I know its a different stove and all, but my stokers with the 125cfm fan 2/3 closed have the flames about 12" high hitting the top of the firebox.

i see from search that the B30 is 45cfm...

edit to add...ooops on my part, the comb fan on the stoker is only 75 cfm not 125. but even so with it 2/3 closed it is still throwing the flames to the top of the firebox.

Thats what I thought. What is your draft reading in the stack? A B30 should be more than enough air for the 70k grate but yet you do not have enough. Its lost somewhere.

The B30s are almost 55cfm actual. There is either too much static pressure from low draft, heavy fines in the coal or air is escaping somewhere.

fins on the fan scraped clean, fan seated correctly in its mount so all air is going into stoker grate area, fan rotating correct direction....etc.

About the only thing I can think of that's worth adding here is .... has the combustion fan been oiled recently? They tend to slow WAY down and get noisy if not, which of course will cut the CFM of airflow way down.

I just closed off the barometric damper. The draft should be very high right now. The stack temp is 190 degrees and I'll measure it again in a half hour.

I think I made progress on my frozen hot water pipe. After wrapping it with one of those electric heat wires and plugging it in, the hot water started coming out of the kitchen faucet by the time I walked back up the basement steps.

Nice.

I am not sure why you closed off the baro. What was it set for? Do you know what the draft actually is? Or are you going by the scale on the baro? Just curious.

I'm trying to make the draft as high as possible. I want to verify if static pressure is the culprit. I also emptied the hopper and vacuumed it out. The only coal left was the small amount covering the grate. I put a fresh bag of Buckwheat into the hopper and sifted it by hand to make sure it was a good grade. I can open the fire door about an inch and look at the fire without the door gasket falling back off. The flames don't look any higher but I'll check again once the "new" coal starts burning on the grate.

Here is a thought from experimenting with my stoker which is admittedly different, but the same theory may apply....

I run my stoker with the combustion fan and feed motor on a timer 3 minutes on and 12 minutes off and the stoker block pass is about 1/2" max. The restrictor plate is about 2/3 closed on the 75cfm fan. It throws flames from the stoker bed to the top of the firebox in this setup during the timer operation or the times the thermostat calls for heat.

I tried running the combustion fan all the time at the same speed by plugging it into an outlet and keeping all other settings the same. After a couple hours running like this, the fire was a a thinner band about 4" back from the grate edge and the flame was about half the height as before. It took about 30 minutes for the feeding of new coal to catch up and get the fire to its normal size on the grate and get the flames back to their complete height to the top of the firebox.

My belief is the combustion fan running full time was burning through the coal on the grates faster than enough new coal could be fed during the timer operation resulting in the lower fire / heat output. Maybe it could have been remedied by increasing the pass length on the stoker to more than the 1/2" setting. I didn't experiment further, i just went back to my regular timer operation of the combustion fan.

My thought is that if your stoker is running full bore but can't feed the coal fast enough to make up for the fan running wide open that could be the cause of your smaller fire and diminished heat output.

Blocking off the Baro didn't expose the problem like I hoped. For a few hours I thought that Dave may have figured it out when he mentioned static pressure from low draft. The stack temp climbed to 210 degrees and the stove did manage to climb up to around 525 degrees. The wind box was not full of fines a month ago, but I will check again tomorrow.

The problem must be either the Fasco combustion fan or the stoker mechanism. How do I test a stoker, can it be disconnected from the coal-trol?

The coal trol wont make your flames smaller. You can plug the feed motor the wall within 5 mins you will be pushing coal off the end. You can also plug the combustion blower direct if it will get rid of the possibility.

This weekend I decided that the noise from my Fasco B30 combustion fan was getting unbearable. I just so happen to work down the road from a Grainger location so I stopped in and bought a new fan. I installed the new fan yesterday hoping for a miracle and a solution for all my stove problems but within a few hours I realized it wasn't to be. The new fan is much quieter than the original fan which is two seasons old, but the new fan didn't make the stove burn any hotter or make the flame any bigger. Strangely, it did raise the exhaust stack temp by 40 degrees and the infrared thermometer now reads 240 degrees. And yet, the stove itself still won't get any hotter than 525 degrees. I'm burning buck which has absolutely no effect on my stove. The stove burns the same on rice. It's funny but my coal supplier didn't even want to sell me buck, he said my stove would get too hot.

When burning buck the stove actually "crackles" like when burning wood in a fireplace. I was fortunate to have the door open and witnessed the cause of the noise. Way back on the grate a small piece of wood burst into flames when I was about to take a picture of the fire. Interestingly, I was able to increase the feed rate to 25 which puts hot coals right to the edge of the grate at a max FR of 99. I'm attaching a before and after picture of the fire crooked as usual because I keep forgetting to turn my iPad horizontal, sorry!
