Question - State With Reasons Why The Testing And Treatment Of Boiler Water Is Essential ?
Answer -
Testing of the boiler water is important to determine that:
- The level of chlorides is within acceptable limits (below 200 ppm) to prevent hard scale and pitting
- The reserve of boiler chemicals within the boiler water is accepted (P Alk above 100 ppm, and Phosphate above 20ppm)
Treatment of the boiler water with chemicals will ensure:
- Alkalinity reserve against boiler water space corrosion
- Scale build-up is minimised
- Enough coagulant levels exist to minimise sludge build-up within the boiler
- The strength of the boiler drum is maintained.
