ABB supplies analytical solutions to ensure well-balanced water chemistry that is vital for optimizing the efficiency steam raising and distribution plant. Optimum positioning of analytical instruments at key points throughout the water and steam cycle and water treatment plant is critical in modern power plants to provide operators with a valuable insight into improving plant efficiency and cost effectiveness.
Key parameters that should be monitored and can be accurately measured using ABB’s analytical solutions include:
- Dissolved oxygen monitoring of steam condensate to avoid inefficient feedwater aeration, air leakage in seals, receivers and flanges, and corrosion and failure of critical equipment
- Hydrazine treatment monitoring and optimization to efficiently remove trace levels of dissolved oxygen in boiler feedwater without over or under dosing that leads to increased operational costs
- Sodium level monitoring in the water treatment plant, condenser extractor pump, polishing plant outlet and saturated and superheated steam distribution loops to minimize corrosion damage
- Silica and phosphate monitoring in the demineralization plant, boiler feedwater, boiler drums, superheater and condenser outlets to minimize scaling that leads to declining power plant efficiency
Our easy-to-use comprehensive analytical solutions deliver accurate, cost-effective results that ensure minimal plant maintenance and maximum operational efficiency.
