Using optimized control technology to improve
efficiency is a solution that has been tried and
tested in power plants of the most diverse types
worldwide. One example of how this can be done
is optimization of the combustion air using the
PROFI CombustOptimizer, which can achieve a significant
improvement in efficiency, depending on the plant.
SPPA-P3000 Process Optimization Solutions optimize
the overall cycle efficiency thanks to better
utilization of the power plant unit, e.g. by
reducing throttling losses and optimizing the
combustion air, the steam temperatures or the
circulating water temperature.
Our solutions:
SPPA-P3000 Low Loss Start: Cost-optimized
startup
Performs continuous analysis, monitoring and optimization
of the overall process and key components, supplies
information about any departure from optimum condition,
calculates the resulting costs, and highlights
improvement potential
SPPA-P3000 Best Point: Quality monitoring
Performs continuous analysis, monitoring and
optimization of the overall process and key
components, supplies information about any departure
from optimum condition, calculates the resulting
costs, and highlights improvement potential.
SPPA-P3000 Sootblower Optimizer:
Cost-optimized sootblowing
Calculates the optimum time for sootblowing
for each separate sootblower group as a function
of the current condition of the associated heat
exchange surfaces.
SPPA-P3000 Combustion Optimizer:
Combustion optimization
Measures pulverized coal flow admitted to a
burner, optimizing operation of the separate
burners on this basis.
SPPA-P3000 Temperature Optimizer: Optimization
of steam temperature
Optimizes control action by the various final
control elements for the spray attemperators,
flue gas recirculation, biflux and triflux control
valves, flue gas backpass dampers and tilting
burners during startup and over the entire load
range. The subordinate temperature controls
ensure that temperatures are reliably held at
their setpoints.
SPPA-P3000 Fuel Optimizer: Fuel optimization
Minimizes fuel cost while at the same time ensuring
stable operation of the power plant unit.
SPPA-P3000 Low Throttling: Minimization
of throttling losses
Reduces the degree of throttling for turbine
valves, feedwater control valves and fan vanes
for forced- and induced-draft fans to the amount
actually needed for these to meet dynamic response
requirements
