Title: Innovations of Hugh W. Nelson
Introduction
Hugh W. Nelson is a notable inventor based in West Hartford, CT (US), recognized for his contributions to the field of combustion engineering. With a total of seven patents to his name, he has made significant advancements in methods related to coal and liquor combustion.
Latest Patents
Among his latest patents is a "System and method for firing coal having a significant mineral content." This innovative approach involves supplying fuel to a conventional pulverized coal-fired furnace at two different levels. The raw coal is classified into a stream of relatively pure coal, which is ground to conventional fineness for burners at the lower level, and a stream of very finely divided coal with a large, heavy mineral content for burners at the higher level. Another significant patent is the "Method for drying and burning viscous aqueous liquors which contain sawdust." In this method, sawdust is mixed with partially concentrated black liquor from pulp manufacture. The sawdust, coated with the solids of the black liquor, is dried by heated air and then fed to the hearth of a chemical recovery boiler. The combustion of the char formed on the boiler hearth produces heat, which causes additional organic material to pyrolize, while the inorganic material combines to form molten smelt.
