Higher coal fineness level will also promote flame stability at lower loads, increasing boiler turn down without the support of oil flames. As fineness increases, fuel balance improves. The finer the coal, the coal and air mixture characteristics are closer to a fluid than solids in suspension. The more fluid coal/air mixture makes achieving
Just want to get some things straight about at what stage in the process it's best to normalize. For the record, I'm working with Aldo's 1075. I've read that one should normalize shortly after the forging is complete in order to relieve stresses as soon as possible. But does this mean right after...
