The analysis includes two parts – (a) an analysis of all startup events at all coal-fired EGUs, and (b) an analysis of startup events at the best performing 12 percent of coal-fired EGUs.1 These results facilitate the identification of the start of APCD operation.Learn More

  • Operational Experience with Startup Optimization for Steam

    startup curves computed on-line are then inte-grated into the existing unit control concept, serving as correction setpoints. The prediction horizon is 60 to 90 minutes, thus covering the entire length of a boiler startup up to the point where the turbine is rolled on steam. This way the most cost-efficient overall operating mode can be computed.Learn More
