The spreader, with its ability to burn a wide range of coals, has been one of the most widely accepted stokers for many years. In recent years it has been increasing in popularity by demonstrating a natural ability to burn cellulose fuels. The same inherent characteristics which give the spreader fuel flexibility when burning coal, are proving to be equally effective in broadening its application to include among other cellulose fuels wet wood. Wet wood as a fuel is usually considered to be those refuse fuels which are by-product in the manufacture of lumber, pulp and paper, and naval stores. They take the form of hogged wood and bark, “spent” chips, and other wood wastes which fall within the size range and moisture content suitable for spreader firing.
