EP0640747A1 - Boiler system pH/phosphate progra

A pH/phosphate program in a boiler water system is controlled by: (1) determining the feed rate of the phosphate to the boiler by adding to a phosphate-feed stream containing the phosphate feeding to the boiler a phosphate-feed tracer in known proportion to the phosphate, determining the concentration of the phosphate-feed tracer in the phosphate-feed stream and correlating the phosphate-feed

Coal Property - an overview | ScienceDirect Topi

Ash can be used as a heat transfer medium, either by its flow countercurrent to the products of gasification and gasifying agents in fixed-bed systems or by provisions in entrained-flow systems 2. In fixed-bed systems, ash accumulates at the base of the fuel bed and is withdrawn by a mechanical grate if unfused or through a taphole if it is a
