An Analysis of Operating Failures of Large-sized Reciprocating Boiler Grates and an Exploration of Measures for Their Elimination

With regard to the operating failures occurring in reciprocating boiler grates of a capacity ranging from 10 t/h to 65 t/h an analysis was performed from various aspects, such as material selection and structural design, etc. On this basis some measures were proposed to eliminate such failures. In addition, an exploratory study was conducted to reduce the weight of boiler parts and components.
