I certainly wasn't planning on waiting until my old supply of coal ran all,but when I called my farmer friend,he was sick,his truck had scrap metal on it & the truck needed to be inspected b4 running for coal. Oh,and then when he & his truck were ready, we got that 18-20" of snow & 3-4 days of terrible wind,which required plowing 2 times each day just to keep the drive open.I was on the phone with fifthg several times to see when it would best suit all of us to get this load of coal & Fri was THE day & it turned out to be a very nice day for the job. Lots of sunshine with just a lite breeze @48* made for a pleasant time to set up the auger,unload & then put the auger away again.My son had off from his work ,so he was able to help me with this whole process as well. I wouldn't have been able to do it by myself,so I had to work around his schedule as well.

I had thought about running to our local coal yard to pick up 1/2 ton or so,but put it off & am now glad I didn't go that route.
Changing coal brands can lead to one needing to change feed/air ratio on the stoker & I didn't want to have to fool with that.

They say that "All is well that ends well". I am happy that the whole process went smoothly yesterday & no more worries about my coal supply for quite some time for me. :D

Have you ever inquired with Gale if they can recommend someone to deliver your coal? Would be good to have plan B in the event your friend or his truck is not available next time.

I did talk to fifthg about this,he said there are tri-axles that come in & could likely haul down this way....

BUT.. Most of them are going to want to haul a full load or at least be paid like a full load. I also have a neighbor who has the big John Deere backhoe & has 3 tri-axle dumps,i want to discuss options with him too.I have been thinking about ways to make a full tri-axle load work here for me.I also need to see if the tri-axles have coal chutes or if I need to make a full width hopper of some kind.
I can fit around 14-15 ton in my empty bin,so if I had a load at 22 tons,i would need to have spare capacity for 7-8 tons. I may just try to find a gravity bin wagon big enough & built heavy enough to load up to 10-12 tons in it. I could then get a tri-axle load,unload as much into the boiler box bin as possible & then put the rest into the gravity bin wagon.I could pull the gravity bin wagon up to the auger with my F250SD & unload it into the boiler box bin as needed.

If I had set up my boiler box as I had initially planned on doing,i could put 25-30 tons in it. But,i listened to a friends suggestion which did result in less pipe footage & that is a positive thing,but also limited my coal bin to the current 14-15 ton capacity.

I tend my boiler every evening after closing my shop. YES, i know the ash tub will hold a few days of ashes,the hopper holds 500# of coal,so it will last for more than 10 days but i like to check everything daily. Tonite after adding 30 # of Gale large rice coal to the hopper,i heard a noise. I stopped & listened,grabbed a flashlite to look around & found a wet spot on the floor near the circulators. Then i spotted water dripping from the bottom of the expansion tank... traced it up to the air vent... leaking from the vent hole. SO, i guess tomorrow i will have to replace the air vent. Any recommended procedure for minimizing boiler water loss to replace the vent ??

Just shut down your circulators, and drain enough water out of the boiler until the pressure gauge reads zero. If the boiler is still hot, get yourself an old towel or something to have absorb any water that might come out when you unscrew the vent. Wear gloves and be safe!

If you want to make this an easier process next time, install a small quarter turn valve between the air scoop and the air vent. Something like this should work:

Took the leaking, made in Italy Taco auto vent out & installed a new ,made in the USA MAID-O-MIST auto vent in & refilled with water.I had planned to do it this afternoon & had unplugged the stoker mid-afternoon,BUT,customers decided to all stop for parts & kept me in the shop until 6pm which is my closing time.After eating supper,i replaced the air vent,boiler temp was under 100* so no hot stuff to touch. Old air vent out,new air vent in,stoker back to running,water temp up to normal.I did not add a shutoff valve,i just replaced the air vent which i had my son pick up .
72 weeks & counting since my wife died,the loneliness was really weighing heavily on me today,so heavy that i got sick,so i just did a simple replacement of the air vent & refilled with water. My EFM520 is back to normal operation,i still am not.
