I operate a vu-40 combustion engineering boiler. we burn bark between 40-65% of humidity. There's big clinker forming on a zone of the grate and i don't know why. First i was thinking that is the cinders reinjection in the furnace by steam nozzles, it's seem like an other thing. Can you help me? Excuse my english im a french canadian.
