protective oxide films (passive films) under boiler conditions (low or zero oxygen levels). However, sulfite is not considered to be a good passivating agent because it does not passivate low pressure boilers, where sulfite is most often used. PassivationLearn More
In low to moderate pressure industrial boiler systems, an initial feedwater DEHA dosage of 300-500 ppb (active DEHA) is recommended. Adjust product feed rates until a consistent DEHA residual of 80-120 ppb has been established in the condensate.Learn More
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2Learn More
Thus the boiler liquid could be allowed to cool down with the consequent reduction in the radiation and convection losses (the standing loss). Boiler controls are now available to avoid maintaining the boiler liquid temperature at the thermostat control sLearn More
