Ash Deposition on Heat Transfer Tubes during Combustion of Demolition Wood

摘要: Wood from old buildings, demolition wood, has a considerable energy value and can be used as fuel. However, the material contains impurities that may have harmful effects. This investigation, carried out in fluidized-bed boiler, focuses on formation of deposits heat transfer surfaces during combustion wood. To avoid inhomogeneity variations composition fuel tests, high-quality wood was two substances are suspected to contribute most deposits, chlorine zinc (from paint), were added predetermined quantities. It found constituent, promoting form potassium chloride also chloride. The or contaminated with deemed not excessively respect corrosion long concentration is low oxidizing conditions prevail.
