What is the impact of excessive silica in feedwater?

• A. Increased boiler efficiency
• B. Formation of scale in high-pressure boilers
• C. Enhanced water quality
• D. Improved steam production rates

Answer: (B)

Excessive silica in feedwater significantly contributes to the formation of scale in high-pressure boilers. Silica can precipitate and form deposits on boiler tubes and heating surfaces due to high temperatures and pressures found in these systems. This scaling can insulate heating surfaces, reduce heat transfer efficiency, and ultimately lead to overheating and failure of equipment. The presence of scale can necessitate increased maintenance efforts, reduced operational efficiency, and a higher risk of unplanned outages. Therefore, managing silica levels in feedwater is essential for maintaining the integrity and performance of boiler systems.
