YUTECH has successfully executed complete Power Plant Automations based on PLC and DCS Systems of different Platforms.
YUTECH Boiler Automation's Special Features:
- Draft Fan Speed Algorithm: YUTECH has developed an algorithm to set optimum speeds for the given Load Condition to ensure the best Combustion Condition.
- Boiler Load Balancing Algorithm of Two or more Boilers: YUTECH has also developed a Special Totally Dedicated Algorithm for Load balancing of Two or more boilers.
- Result: Optimum Combustion Saves Fuel and improve Carbon Footprint by way of reducing CO while reducing Excess Air to the Furnace thus also Saving Power for Draft fans.
- All boilers run at exactly the same desired loads and Steam Pressures of each Boiler are always within 0.05 Bar of each other.

Power Plant Automation Ensures Higher Efficiency:
- Improved Efficiency by 2-55 depending on the Plant.
- Improved Steam to Fuel Ratio due to increase in FW Temperature and increase in Boiler Efficiency (Please See Fuel Ratio Equation).
-
Optimum Combustion reduces Unburnt Fuel Losses this is evident from:
- Decrease in Oxygen and Increase in Carbon Dioxide Percentage in Fuel Gas and the same time Reduction in excess Air Percentage.
- Reduction in Fuel Gas carbon Monoxide Percentage.
- Reduction in Excess Air means optimum usage of fan Drives and thus Power saving.
- Maintained Steam Drum Level with Pressure Compensation Ensures Optimum Steam Generation while compensating.
