: We burn wood dust and shavings primarily made up of Red Oak at about 7% moisture. I'm looking for some help in determing proper air/ fuel mixtures. We have firebox temps. in excess of 2000F and causing fusion. The ash comes out in chuncks not a powder like it should. Under grate temps are around 300 to 350F. and the grates are covered with a hard layer of ash. The refractory side walls get a glazed look and the over fire air nozzles get covered with the melted ash.
what is your stack temp? sounds like you do not have enough excess air. we burn coal and need to have around 30% excess air to keep from hitting the fusion point of our ash
