Feed Water Treatment to Avoid Corrosion -

2021-1-7 · Oxygen together with high temperature is highly corrosive for the carbon steel piping used in steam systems. To avoid corrosion the oxygen in the make-up water for saturated steam production should be removed by using some kind of scavenger chemicals and/or deaeration towers. Scavenger Chemicals. Some commonly used scavenger chemicals are

Determination of High Temperature Corrosion Rates

Downloadable! The use of low-emission combustion techniques in pulverized coal-fired (PC) boilers are usually associated with the formation of a reduced-gas atmosphere near evaporator walls. This increases the risk of high temperature (low oxygen) corrosion processes in coal-fired boilers. The identification of the dynamics and the locations of these processes, and minimizing negative
