How to Improve Efficiency First Step: low hanging fruits Improve efficiency by improving operation and maintenance – SI System 24/09/2008 ES-ST_ING_neu
How to Improve Efficiency Next Steps: ● Audit or „map“ the plant using off line ۷ modelling tool e.g. Ebsilon ● Online optimization tool PADO ۷ ● Online fault tree detection system SRft - ● Online fault prediction system SPC ۷ ● Online fault detection system SWAN - ● Online life time monitoring SR1 for better - planning of inspections and maintenance 24/09/2008 ES-ST_ING_neu
Why to use the software tools ? DCS has the information needed to do the calculation of efficiencies and heat ratesBut what are the limitations ? 1. DCS does not give the system wise efficiencies so you do not know where the losses occur 2. Data from I/O points e.g. Temperature, pressure mass flow could be wrong because of sensor errors, bad connectors etc. That makes calculationerroneous. 3. DCS does not giveadvice what to do 24/09/2008 ES-ST_ING_neu
PADO: Online Optimization Sequence 1. All relevant data from DCS which goes into calculation need to be validated i.e. all implausible values have to be replaced by plausible values 2. All calculations must be done every 5 minutes (not only once a day) since the quality of coal and combustion process is changing. Threfore the state of heating surfaces must be monitored constantly. 3. Results should be presented in user friendly manner: state of comonents indicated by green, yellow, red and losses expressed in Rp per hour 24/09/2008 ES-ST_ING_neu

Advantages of PADO ● Improving the quality of measurements by data validation ● Evaluation of boiler, turbines, condenser and other components ● Optimization of unit operation (sootblowing, setpoints) ● Calculation of what-if scenarios ● Generation of daily and monthly reports ● Enhance the efficiency of the power plant ! 24/09/2008 ES-ST_ING_neu
PADO Test Questions 1. What are the limitation of DCS systems in respect to calculation of heat rates and efficiencies with raw data ? 2. Give simple example how can we prove that the data validation is necessary for calculation of heat rates 3. Why the calculation should be carried out every 5 minutes ? 4. What are optimization modules in PADO ? 5. Which actions can be carried out to improve efficiency of the unit ? 24/09/2008 ES-ST_ING_neu
PADO Test Questions 6. Give some examples of controllable losses? 7. Are heat rate correction curves used in PADO ? 24/09/2008 ES-ST_ING_neu
