I left some of my supply of coke outdoors for about 3 years. When I went from using coke that was stored inside (and had very little clinker) to the coke from outside, I had tuyre plugging clinkers. It runs like thick syrup and really slows my work down. Has anyone else experienced this? Also I have problems getting good first time welds with coke as opposed to coal. It seems like the coke lets too much air pass thru the fuel. I have a hair dryer with two speeds. The low speed doesn't get it hot enough and the high speed is great for heat, but then too much air. If I put coal in with the coke it is better, but I would rather do it all with coke.

Sounds like most of the water has evaporated, and it's turned back into syrup. [sorry -- couldn't help myself].
You could try adding an air gate so you can set the blower on high but dial back the flow some.

I don't think the coke "absorbed" any clinker making material. Rain didn't hurt it. In it's coal form it was in the weather for a few million years. I like coke but have had same problem welding. You have to really smoosh some of it into fines when you go to weld if you don't want to use any coal. I mix the two together regularly for all my coal forge work...

well with coke i use a different fire from coal and for forge welding it probably needs to be deeper so there isnt the air directly on the iron ..also it dosnt insulate as well as coal so got to keep that in mind depending on the type of forge you use . ive gotten used to useing it but it takes practice . i find that for forge welding i like it better than coal ... its a lot cleaner . ive got a fairly deep firepot i use it takes more air than coal tho and you might have to run your blower on high and put a bit of paper across some of the inlet to get the right amount of air ... i like hand crank blowers cause you can ajust them to just the right amount.. good luck!
