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
Hydro-wall design with water circulating completely around the combustion area - no refractory combustion chamber or separate base Designed for easy maintenance - all heating surfaces can be cleaned from the left side of the boiler Cast iron sections areLearn 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

Split Cast Iron Block Assembly. Splitting boiler block for easy transportation into boiler room (only if boiler is supplied as block) 1.Drive wedges between cast iron sections to split boiler block. Only drive wedges in at the appropriate positions (whereLearn More
Wrought iron boilers corrode far more slowly than their modern-day steel counterparts, and are less susceptible to localized pitting and stress-corrosion. That makes the longevity of older wrought-iron boilers far superior to that of welded steel boilers.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
