IF THE BOILER GOES COLD THE SULFITE IS NOT AS EFFECTIVE. AN OFFL-LINE BOILER SHOPULD BE HEATED UP TO KEEP IT ACTIVATED. : I have a small 150# Bryan water-tube boiler that has developed localized pitting in several tubes resulting in leaks. The boiler was regularly treated by a professional chemical consultant. He says that by leaving the water in the boiler overnight & weekends, the oxygen scavenging sulfite is depleted and loses its effectiveness. The boiler typically operated 40 hrs per week.
: The boiler has been replaced. Does sodium sulfite evaporate or leak out or otherwise disappear overnight? Is there a way that the operators can maintain the required levels of sodium sulfite in the boiler? Most of the condensate is returned in this system.
