Problem
Consider two identical boilers. Each receives 100% makeup at a TDS of 100 ppm. Each boiler is operated with 3100 ppm of TDS in boiler. One has makeup treated by a zeolite softener and the other has makeup treated by an RO softener with an output stream at 5 ppm of TDS. Each boiler makes 3000 1b/hr of steam. What is the difference in blowdown rate in 1b/hr?
