Dissolved oxygen is the main source of corrosion in boilers. The concentration of oxygen in boiler waters should be below 0.05 ppm for low pressure boilers and less than 0.01 ppm for high pressure boilers (~ 500 psi). Oxygen enters the boilers through raw make up water and also through infiltration of air into the condensate system.
