I had a very nice load of Red Oak delivered two seasons ago. Moisture content freshly split is around 12%. Logic suggested that stuff would burn very hot and longer burn times than other species. Yesterday, I brought in some different woods from other piles that had been stacked for shorter times. Mostly Maple with some Ash mixed in. Moisture content up to 18%. They are shorter, but fatter pieces than the Oak, so I figured it would be good for the bottom layer of a top down fire. I was surprised to find the mixed load burned both hotter and longer than the Oak alone. Has anyone had a similar experience? I'm glad I stumbled onto this before I blew through all the Oak, but I am scratching my head as to why this is. I'm thinking it has to do with the various species burning at peak temp and off gassing at different times, but it's just a guess. Would love any insight.
