I'd grab it if were me. I burn as much Pine as I can get in my owb. The Austrian around here is dying & my least favorite due to the fact that it doesn't dry well unless split. That being said if you hand split mark & cut through the "knot sections" & it will split more easily. I prefer ewp because it dries better & burns cleaner. Not sure why a boiler would need more cleaning burning Pine. I use Pine to burn down coal beds to make room for better wood in cold weather. I would happily use Pine & Silver Maple for about 1/2 the burn season if I could source enough. Save the Oak, Hard Maple & Locust for the real cold.
I know guys that burn pretty much anything in their OWB, it doesn't matter to them seasoned or not, pine or knot (pun intended). On a side note, some people break off the butt ends of the branches to use as fire starters, because that is where pine resin collects. It's the same as fatwood fire starter you can buy. But I think the pine tree should be dead for a few years before collecting the fatwood from it. I haven't done it, so someone can correct me if I'm wrong about the tree being dead.
I’ve cut a few pines. When my neighbor had three biggins blown over, I did the cleanup and removal for them. Darn sap on my chaps and gloves... it’s a pain but after it gets you a few times, you start to manage/minimize touching it. Seasons quick and burns fine, especially for starting a cold stove. I save splits for that purpose. If my coals are very low, a few pieces will get going rather quick and then the hard wood goes in. I’d do it if I were you.
Uh.... NO! If you already have a wood supply, I'd say "Pass that tree up." Your first picture says it all. Hell No. Just looking at that tree gives me grief. A wolf tree with inter-grown knots and giant limbs. It's going to be ugly inside. Twisted, demonic wood from hell. No, no and No. I have some pine in my pile, simple stuff, nice straight stuff and it is kicking my azz with an 8 pound maul. The maul is literally bouncing off it, and laughing at me. The park people were so happy to have me come cut this up. "Easy, straight wood!" I thought as I backed right up to it. This is live Ponderosa Pine, so some differences to account for on your end.
